The Bradford Manuscript.-The manuscript of Gov. William Bradford's "History of the Plymouth Plantation" was formally received at the Statehouse, May 26. An address was made by Senator Hoar, who mentioned the previous attempts to recover the document by John Sinclair in 1860 and by John Lothrop Motley in 1869. Nothing came of proposed attempts in 1877 and 1881. Then came the last and successful appeal started by the Senator himself.

This manuscript disappeared during the Revolution, and was supposed to have been taken by the British soldiers who occupied the Old South Church as a riding school, or to have been carried away by Gov. Hutchinson in 1774. It was discovered in the Fulham (England) Library, still bearing the bookplate of the New England Library.

Legislative Session.-The Legislature convened Jan. 7, and was in session till June 12. The new State government was inaugurated Jan. 7. Politically the Senate stood: Republicans, 33; Democrats, 7; and the House: Republicans, 181; Democrats, 58, and 1 Prohibitionist.

There was a contest before the Legislature in reference to the election of councilor in the Fourth District. The election commissioners declared the Republican candidate, Isaac B. Allen, to have been elected; but the Democratic candidate, John H. Sullivan, alleged that more than 340 ballots that should have been counted for him were improperly rejected because the mark which should have been placed in the square after his name was by mistake placed in the square opposite a vacant line just below his name, and these ballots were cast by persons who had voted for all other Democratic candidates. His opponent contended that the Legislature had no authority to go behind the returns. The legislative Committee on Election Returns decided that it was not necessary in this case to determine this important constitutional question, because the majority were of opinion that the ballots so marked should not be counted for the petitioner. The minority were of opinion that there should have been an examination. The majority report was accepted, and Mr. Allen was sworn into office.

Among the more important acts passed was that giving a charter to the Boston Elevated Railroad Company. The company promises to give five-cent fares and free transfers over all systems owned, leased, or operated by it, and if it pays dividends it will pay a franchise tax based upon the gross earnings of all such lines.

An act was passed which was intended to stop the killing of birds for ornamental purposes. As few Massachusetts birds are used in millinery, the act seems to have failed of its intent.

The Governor was authorized to appoint a special commission to investigate the subject of the relation between street railways and the municipalities of the State. He appointed Charles Francis Adams, William W. Crapo, and Elihu B. Hayes.

Among acts passed were these:
Providing a special penalty for theft of bicycles.
Providing for inspection of dairy products.
To incorporate the Roman Catholic archbishopric

of Boston.

Relating to newspaper libel. Increasing the aid given for school purposes to towns having low valuations.

Resolution relative to exercises in the public schools commemorative of the inauguration of the President of the United States.

An appropriation of $250,000 was made for use in the extermination of tuberculosis in cattle. The mill school-tax bill was to authorize a State tax of a dollar on a thousand for the support of public schools. This the Governor vetoed on

the grounds that it would not necessarily increase the sum to be expended for their support, for it contained no provision preventing the towns and cities which will receive money under the proposed tax from reducing their own appropriations for schools by an equal amount; that it would not tend to aid the weaker and overburdened communities in maintaining schools, since a large proportion would go to cities and towns.

Political. There were five tickets in the field for the State election in November. They were: Republican For Governor, Roger Wolcott; Lieutenant Governor, Winthrop Murray Crane; Secretary of the Commonwealth, William M. Olin; Treasurer and Receiver General, Edward P. Shaw; Auditor, John W. Kimball; Attorney-General, Hosea M. Knowlton.

Democratic National: For Governor, Dr. William Everett; Lieutenant Governor, James E. Cotter; Secretary of the Commonwealth, Bernard M. Wolf; Treasurer and Receiver General, Horace P. Tobey; Auditor, Harry Douglas; Attorney-General, William W. McClench.

Democratic: For Governor, George Fred Williams; Lieutenant Governor, Christopher T. Callahan; Secretary of the Commonwealth, Charles D. Nash; Treasurer and Receiver General, Thomas A. Watson; Attorney-General. John A. O'Keefe.

Socialist-Labor: For Governor, Thomas C. Brophy; Lieutenant Governor, Edward A. Buckland; Secretary of the Commonwealth, Addison W. Barr; Treasurer and Receiver General, George A. Brown; Auditor, Joseph Ballam; Attorney-General, William Harrison.

Prohibition For Governor, John Bascom ; Lieutenant Governor, Willard O. Wylie; Secretary of the Commonwealth, Edwin Sawtell; Treasurer and Receiver General, Robert C. Habberley; Auditor, Herbert M. Small; Attorney-General, Wolcott Hamlin.

The People's party held a State convention Sept. 24, but put out no State ticket, although the "middle-of-the-road" section were opposed to fusion. The power to make nominations was given to the State Executive Committee, and it was instructed to confer with the Democratic party at its State convention. In accordance with these instructions fnsion was effected, and one place on the Democratic ticket, that of Secretary of State, was given to the Populist candidate. Charles D. Nash.

At the Democratic convention, held in Worcester, Sept. 28, the Chicago platform was approved, and the proposal to substitute bank notes for national notes was condemned,

The resolutions favored legislation to encourage municipalities to establish their own systems of water supply, gas and electric lighting, heat and power distribution, street-railway service and other service of similar character; postal savings institutions: provisions to enforce the existing laws requiring returns of property for taxation; taxation of personal property at a uniform rate in all cities and towns; a tax on inheritance and successions; an income tax; abolition of irresponsible commissions; popular election of Senators; an eight-hour day for labor; more efficient inspection of factories, etc.; and amendment of the employers' liability act. They declared in favor of settlement of disputes between nations by arbitration, but were opposed to a treaty with one nation exclusively.

The National Democrats issued an address to the public in which they said:

"Our party is organized by those who believe that there ought to be a trustworthy political party pledged to establish a sounder and better system of banking and currency; to practice honesty and economy in expenditures; to use public office as a

public trust, and to eradicate the spoils system in both appointments and legislation; a party opposed, therefore, to protection, to paternalism, to fiat money, and to class legislation. It is an old party in its steadfast maintenance of the unchanging principles of justice and equal rights and in its disinterested devotion already fully proved; a new party in its clear and resolute aim to restore popular government in the United States to the purpose from which it is now diverted-the service of the American people."

At the Republican convention, in Boston, Sept. 29, the principles of the party were reaffirmed and the national administration approved. The platform said further:

"The Republicans of Massachusetts maintain their fundamental belief in the unsectarian free public school. They dare insist upon a full enforcement of the liquor law. They believe that the frequent approval of loans outside the debt limit is against wise municipal economy."

The election resulted in favor of the Republicans. The vote for Governor stood: Wolcott, Republican, 165,095; Williams, Democrat, 79,552; Everett, National Democrat, 13,879; Brophy, Socialist-Labor, 5,301; Bascom, Prohibition, 4,948.

At the city election in Boston, Dec. 22, Josiah Quincy, Democrat, was re-elected mayor by a plurality of 4,079.

At the town elections in March the most excitement was caused by the license vote. Of 85 towns reported, 13 voted "Yes," against 12 in 1896. The vote was changed in seven or eight.

MECHANICS, JUNIOR ORDER OF UNITED AMERICAN. This organization is an outgrowth of the American Mechanics' Union, established July 8, 1845, as a fraternal society, with headquarters in Philadelphia. This latter, afterward called the "Order of United American Mechanics," was the practical result of a movement begun in 1843 to restrict immigration and in several other respects to secure for native Americans privileges in keeping with the spirit of the Constitution. The restriction of immigration was given the first place in a statement of principles and leading ideas entertained by the founders of the order. Following this came advocacy of the Bible as a reading book in public schools; complete separation of Church and state; selection of native Americans as legislators, administrators, and executors of the law. The parent order published at the time of its inception six declared objects: 1. To assist one another in obtaining employment. 2. To assist one another in business, by patronizing one another in preference to foreigners. 3. To assist the unfortunate in obtaining employment suitable to their afflictions. 4. To establish a cemetery for deceased members. 5. To establish a funeral fund. 6. To establish a fund for the relief of widows and orphans of deceased members. Chief among the men who were active in establishing the parent order were Luther Chapman and Richard G. Howell.

The Junior Order of United American Mechanics was instituted May 17, 1853, the first meeting being held in the Concord schoolhouse, Germantown, Pa., not far from the historic battlefield. Its motto is Virtue, liberty, and patriotism." Its watchword is "Patriotism." The credit of bringing this order into existence is largely due to Gideon D. Harmer, Elliott Smith, and William M. Weckerly. The declaration of principles includes the following opinions and resolutions:

"That the constant landing upon our shores of the hordes of ignorant, vicious, and lawless criminals of the Old World should be viewed with alarm by the loyal and patriotic citizens of this country. "We affirm a warm and hearty welcome to all

not willing to bow allegiance to that flag which is powerful enough to protect them as well as us in the exercise of all civil and religious liberty.

"We affirm our devotion to the public-school system of this country. We believe in compulsory education, and that all teaching in our schools should be in the English language, to the end that future generations may be able to take their place in the ranks of our country's workers, educated in the history, customs. and manners of Americans.

"We guarantee to every man the liberty of worshiping God according to the dictates of his own conscience, and would give every assistance to protect all in the exercise of this liberty, but we object most strenuously to the interference of any Church, no matter under what name it may exist, in the temporal affairs of this country.

We believe that the Bible should be read in our public schools: not to teach sectarianism, but to inculcate its teachings. It is the recognized standard of all moral and civil law; we therefore believe that our children should be educated in its teachings, but that no dogma or creed should be taught at the same time.

"We believe that patriotism and love of country should be instilled into the hearts of children, and that, with the sacred words of mother,' 'home,' and heaven,' our children should be taught that our flag is the symbol of all that makes a home for We would place a flag upon every public school in our land, and a Bible within, and the object lesson therein set forth should be a beacon light in every storm that threatens to engulf us.

us.

"In the strictest sense we are a national political organization, but we oppose with unanimity the slightest taint of partisanship. Our Country' is our motto, and we keep this motto steadily before us."

The qualifications for membership are these: A white male person, born in the United States of North America, or under the protection of its flag. Of good moral character. A believer in the existence of a Supreme Being as the Creator and Preserver of the universe. Opposed to union of Church and state. Favorable to free education and the American public-school system. Between sixteen and fifty years of age for beneficial membership; over fifty years, honorary membership.

The weekly dues are from 10 to 15 cents, and the minimum entrance fee for charter members is $2. Sick benefits range from $2 to $5 a week. Funeral benefits are graded from $20 to $250. The following extract from an official statement recently issued gives the present condition of the organization, or rather its condition at the end of 1896. The figures for 1897 are not yet complete, as the work of the order extends over the entire country: The amount paid for sick and funeral benefits to Dec. 31, 1896, is $3,500,000. The amount received by subordinate councils is $9,000,000, and the amount paid out for all purposes is $7,500,000. The report of the national secretary to the National Council shows that the year ending Dec. 31, 1896, notwithstanding the stress of the times, was an evidence of the progressiveness of the Junior Order. It is as follows: Number of councils Dec. 31, 1896, 2,237, a gain of 106. Membership Dec. 31, 1896, 177,732 (about 200,000 at this writing), a gain for the year ending Dec. 31, 1896, of 10,899. The receipts of subordinate councils for the year ending Dec. 31, 1896, were $1,562,287.28, being a gain of $284,943.51 for year. The amount paid for benefits and relief during the year ending Dec. 31, 1896, was $550,860.29. The amount in the treasuries of subordinate councils Dec. 31, 1896, was $1,624,846.94, being a gain over the last year of $192,210.42.

the

In addition to the foregoing, the National Council has established a National Orphans' Home at Tiffin, Ohio, for the care of needy orphans of deceased members. The home has been in operation about one year, and 38 little ones have found their way to it. The property and improvements are valued at $50,000, and are clear of debt.

"Our various State legislative committees have secured the enactment of laws providing that the United States flag shall be displayed on all public schools; providing for compulsory education and for free text-books, and much other legislation for the protection and advancement of the publicschool system.

"The National Legislative Committee is endeavoring to secure from Congress laws to restrict immigration, to amend our naturalization laws, to prevent sectarian appropriations, to prevent the desecration of our flag, and other laws that are truly American in their operation."

The word "junior" in the title has no relation to the age of members. It was adopted to distinguish the order from the Order of United American Mechanics, and has no other significance. The word "mechanic" is not construed literally; it embraces every pursuit.

The following detailed exhibit, compiled from the last official report, gives an idea of the strength of the order in the respective States and Territories: The actual membership, as reported up to and for Dec. 31, 1896, was: Maine, 542; New Hampshire, 645; Vermont, 955; Massachusetts, 1,468; Rhode Island, 569; Connecticut, 879; New York, 5,343; New Jersey, 26,676; Pennsylvania, 78.803; Delaware, 2.081; Maryland, 16,987; District of Columbia, 1,088; Virginia, 5.271; West Virginia, 7,044; Kentucky, 998; Tennessee, 1,178; North Carolina, 974; South Carolina, 569; Georgia, 274; Texas, 660; Ohio, 13,534; Indiana, 1,041; Illinois, 501;

Michigan, 249; Wisconsin, 225; Minnesota, 482; Iowa, 280; Missouri, 1,507; Nebraska, 186; Kansas, 322; Colorado, 2,112; Montana, 211; Washington, 355: Oregon, 488; California, 2,452.

The official head of the order, known as the national councilor, is Joseph Powell, of Denver, Col. ; the secretary is Edward S. Deemer, of Philadelphia. The next meeting will be held in Louisville, Ky., June 21, 1898.

METALLURGY. Iron and Steel.-The past ten years was characterized by Mr. E. G. Spilsbury, in an address before the American Institute of Mining Engineers, as having been marked by many and varied improvements in all branches of mining and metallurgy, not so much in startling inventions as in the better adaptations of what was already in use. Among the improvements in mining are the adaptation of the steam shovel, the application of electrical power for mining, concentration, and conveyance, and improvements in wire-rope haulage and transportation. Radical and progressive changes have been made in furnace practice, by means of which increased production is obtained at lessened cost. Among the special improvements in the metallurgy of iron is the mixer of W. R. Jones, by means of which the products of one or more furnaces are tapped into a receiver and there so thoroughly agitated and mixed as to furnish an absolutely uniform metal for further treatment in the manufacture of steel. By allowing the fluid metal to remain a certain time in these mixers, or by the use of lime, the iron is thoroughly desulphurized. The silicon contents are lessened by casting the pig metal in chills, instead of into sand direct, and by Benjamin Talbot's process of pouring the metal as it is tapped from the furnace through a bath of molten oxide of iron. Improvements in the conversion of pig metal into steel have been made chiefly in the open-hearth processes and in the line of mechanical rather than of metallurgical adaptations. These have made it possible greatly to increase the size and output of open-hearth furnaces. Among these improvements are the mechanical charging machines of S. T. Wellman and the Wellman revolving furnaces. Improvements in basic hearths and linings made by Benjamin Talbot have greatly reduced the expense of parts of the process. The Bertrand-Thiel continuous open-hearth process has warm advocates in England. The Stockman process, by the use of nitrate of soda as a means of oxidizing the objectionable metalloids, does away with the necessity for all expensive blowing machinery. Mr. Edison's plant for mining, crushing, concentrating, and finally briquetting magnetic iron ore at the Ogden mine, New Jersey, is mentioned as a theoretical development and improvement of the very highest type, but its cost is very great.

Of two forms of iron of marked peculiarities, described by T. H. Norton, one, part of a mass taken from a deep crevice in the hearth of a blast furnace after the furnace was blown out, where the iron had been maintained in a liquid condition for more than a year, and had then cooled and solidified very slowly, was of a light, silvery color, and exhibited a very marked crystalline structure, with rectangu lar cleavage. It was, however, the reverse of brittle, and was highly malleable. The drill made but slight impression upon it. Portions were tempered, and attempts were made to pulverize them; a slight crumbling was manifested at first, but after a few strokes of the hammer the fragments became perfectly malleable. The piece could be split easily with a chisel, especially along the lines of cleavage. On analysis the only serious impurity in the metal was found to be phosphorus. The second specimen was the result of the prolonged action of the inner

part of a nonluminous Bunsen flame on ordinary steel; the steel having served to support the mantel of a Welsbach lamp which had been in steady use for two years, and having been exposed during that period to the combined action of a high temperature and the gases of the inner cone of the flame. As a result the steel had become so brittle that the upper half crumbled as easily as chalk. The lower part, less exposed to the flame, was covered with a brittle layer, while the central core was still pure steel. About six sevenths of the carbon seemed to have disappeared from the brittle part.

Hard, brittle white-iron castings may be softened and annealed, according to George Parker Royston, either by oxidizing the carbon-the older method, used and described by Reaumur in 1722-or by changing it from the combined to the free or graphite state. In the former method, the one most generally followed, the metal is heated in oxide of iron at a bright-red heat for a considerable period, the length of which is dependent on the thickness of the bar to be annealed. It may also be placed in lime, sand, or bone ash in lieu of oxide of iron, provided the atmosphere is used as the source of oxygen. The iron must be free from manganese and sulphur, or the elimination of the carbon will be delayed. The method by decomposing the carbide into graphite and free iron is effected by more or less continued heating between 850° and 650° C. Iron castings produced by this method are quite as soft as those obtained by the Reaumur method, but on account of the graphite present no bend can be obtained. There is no limit to the size of the castings that may be made, a large piece taking quite as short a time as pieces of smaller size. In another method of softening white iron discovered by the author the castings are carefully packed in some nonoxidizing material and heated to the temperature at which the iron would solidify after fusion-or about 35° C. below the melting point of the metal. As a result of this treatment the white iron becomes changed into a steel containing 15 per cent. of combined carbon, the remainder of the carbon being distributed through the metal in the form of finely divided graphite.

From his investigations of the contraction and deformations of iron castings in cooling from the fluid to the solid state, Mr. Francis Schumann deduces the conclusions that the deformation of prisms due to unequal contraction can be overcome by providing counter-deformation in the pattern, or by the addition of auxiliary parts that can be readily removed from the casting. In complex machinery castings the design should be so modified or chosen as to result in the least differences in the rate of cooling. Sudden changes in form cause severe initial stresses, if not fractures, and should be rigidly avoided. Imperfectly proportioned flanges, ribs, or gussets added to the main body of a casting for the purpose of increasing the strength of connections, may be sources of weakness. Hollow cylindrical columns, although cast of even thickness and left in the mold till cold, may become crooked by reason of the unequal rate of cooling between the upper and lower halves, due to the currents of air passing through the column and clinging to the under side of the upper half after the core arbor is removed, which is usually done shortly after pouring and while the casting is still red hot. This deformation is avoided by stopping the ends with sand immediately after the withdrawal of the core. Greater attention to the laws of cooling and correct forms and proportions of castings will result in increased strength and economy, besides the avoidance of annoying crooked castings and mysterious breakdowns.

The general advantages claimed to accrue from the addition of pure aluminum and ferro-aluminum to cast iron, as given in a paper by J. A. Steinmetz, are that it makes the iron more fluid, that it renders hard iron softer, that castings thus made are freed from hard spots and blowholes, that it lessens the tendency of the metal to chill, and increases the resistance of the metal to chemical action. It is also said that while good soft iron is made more fluid and benefited to some degree, yet the advantages of treating with aluminum are most evident with poor, hard white iron. It is an unquestionable fact, Mr. Steinmetz says, that the addition of aluminum very considerably affects the quality of the castings for the better. The general conclusion from tests made is that with white iron small additions of aluminum, such as would be used in ordinary foundry practice, increase slightly the fluidity; of 1 per cent. of aluminum and more decreases the fluidity. Gray iron is rendered decidedly less fluid by any addition of aluminum. Aluminum appears to reduce the shrinkage if enough is added. Perhaps one of the most striking results of the experiments is the increased time during which aluminum-treated iron will remain molten. This property of keeping fluid longer is of direct usefulness in a foundry where it is necessary to run a large number of small castings, when there is usually much trouble in keeping the ordinary metal fluid, unless it was very hot to start with. The general results prove that the molten bath of iron with aluminum will stay fluid twice as long as one without it. Another consideration is that cleaner, more solid, and softer castings are universally obtained, with a large reduction in the percentage of defective castings.

In a paper read by Prof. Gay before the American Society of Mechanical Engineers on the yield point of iron and steel, additional information is given regarding the increase of the ultimate strength and of the elastic limit of those metals. A test piece of iron, which under ordinary trial was shown to have a tensile strength of from 50,000 to 53,000 pounds per square inch, was tested just to the yield point, then allowed to rest free of stress for two weeks, and then tested again. The yield point was found to be considerably higher. The test was then repeated at times from one to three weeks apart till seven tests in all had been made, each showing a further increase in the yield point till it had been raised to 55,900 pounds per square inch, or considerably beyond the normal ultimate strength of the iron. The elongation in each test, except the last, was not carried beyond the yield point. In the last test it was continued to rupture without any increase in stress beyond the yield point, the total elongation of the piece being only 14.5 per cent., or one half of the elongation of the same iron when tested in the ordinary manner without resting. In a test of a bar of steel the elongation was carried to a point considerably beyond the yield point, rested seventeen hours, tested again when the yield point was found much higher, tested twice again with intervals of twenty-four hours, when a still higher yield point was given each time. The total strength of the bar was thus considerably increased over that of the bar tested in the usual way, but the elongation was reduced one half.

In his studies of the various aspects of the loss of strength in iron and steel by reason of use, Mr. Thomas Andrews has made exhaustive microscop ical, chemical, and physical examination of rails of known age and condition of service on main lines of railway, and has obtained much valuable information on the subject. In a lecture upon it he

showed the difference between loss of strength from mechanical abrasion and the deterioration of the ultimate crystalline structure of the metal under the fatigue of stress consequent on the presence of internal micro-flaws. He also demonstrated the effect of low temperature in reducing the impact resistance of rails, the influences of corrosion, the manner in which vibratory stress induces microscopic internal growing flaws in rails, and the influence of various kinds of ballast on the permanent way.

Speaking on "Some Present Possibilities in the Analysis of Iron Steel," Mr. C. B. Dudley observes that few substances have received more study and few present chemical problems more difficult of solution than pig iron; and including the work that has been done upon the substances associated with it in manufacture and the substances derived from it, it is safe to say that the chemical work that has been done in connection with it has been greater than with any other substance in Nature. The complexity of pig iron is very great, and consequently the analytical problems presented are far from being easy of solution. Eighteen distinct substances besides iron are enumerated as having been found in analyses of it, 12 substances as alloyed with some form of iron or steel, and the 3 gases, oxygen, hydrogen, and nitrogen, as occurring in these metals and believed to have important influences on their physical properties. Having reviewed the present condition of the methods of analysis for five of these many substances-carbon, phosphorus, silicon, sulphur, and manganese-the author finds all the methods more or less imperfect and needing more work. "What," he asks, "will be our condition as chemists if, as seems probable, nickel, chromium, aluminum, tungsten, and the gases oxygen, hydrogen, and nitrogen, either free or combined, within the next few years come into prominence as constituents of iron and steel and are made elements in important commercial contracts? Still further, thus far our methods are concerned almost entirely with the total contents of the various constituents we are determining. We know very little about the compounds of the various constituents occurring in iron and steel, with the metal or with each other. Is the phosphorus present as phosphide or phosphate, or both? How besides as sulphide does the sulphur occur? Do the various carbides which are revealed by the microscope, and which are believed to be so closely dependent on the heat treatment which steel receives, and which are so intimately related to the value of the metal, differ from each other in carbon contents, or only in crystalline form? Who will be the first to isolate any of these carbides? Who will first give us a practicable, accurate, and sufficiently rapid method for determining oxides in steel? Who will first completely investigate the relation between the chemistry and the chilling properties of cast iron? And who will first give us a study on the form in which nitrogen occurs in this metal and a simple and accurate method for its determination? The advantages to be derived from the formation of an international laboratory for investigating the methods of analyzing iron and steel were pointed out by Dr. H. Wedding in a paper read before the International Congress for the Unification of Methods of Testing. It was represented that the relations of buyers and sellers in the iron and steel trades would be put on a much safer basis if standard methods were appointed so that any chemist of ordinary skill could be trusted to carry them out. This could best be done at an international central laboratory, where the work done in various countries could be collected and reduced to a common standard. A competent director for such a labora

tory had been found in Baron Jüptner von Jonstorff.

In a communication to the German Journal "Stahl und Eisen" concerning the microscopic examination of steel, Prof. Ledebur gives the results of experiments made by him upon the effects of service on steel rails. They show that old rails, as well as those that have been used for only a short time, have a surface layer of harder steel than the rest of the body. This layer, distinctly recognizable under a microscope, averages about 1 inch in thickness, and when it is removed by filing the rail is brought to normal strength again. The effect of the continued use of a rail appears, therefore, to be to develop a thin layer of very hard nature at the wearing surface, which can be removed by reheating. Should the surface, however, show cracks the rail can not be restored to its original strength.

The Ellis-May steel process consists essentially of making the castings in a vacuum, thus precluding, it is claimed, the possibility of occluded air or gases in the metal. The system comprehends a closed casting chamber connected with other vacuum chambers by pipes and valves; these are exhausted by powerful vacuum pumps. When the metal is ready to be run into the mold the valves are opened, the air in the casting chamber is instantly drawn off, and. the casting taking place in vacuo, a flawless, homogeneous piece is claimed to be the result. It is represented, also, that the process entails a considerable saving in metal, since there is no waste in large castings like that which exists with the ordinary process. Some steel makers say, however, that the process is accompanied with considerable difficulty and the operation of the machinery is costly.

"Nickel steel," says Mr. William Beardmore, "has won its spurs, and proved itself worthy of the confidence placed in it by those to whom its remarkable qualities are best known." The results obtained by the author in the manufacture of this alloy for a large variety of purposes have been, he says, eminently satisfactory. It fulfills all the purposes of a metal that can be worked without any special care on the part of the artisan; which in shipbuilding will enable us to reduce the scantlings, take from the weight of the boilers, and add to the strength and reliability of the propeller shafts; and "which will give the same results to-day or tomorrow in China or Peru." It can be bent and punched as successfully as ordinary carbon steel. It has a higher elasticity by 31 per cent. than ordinary carbon steel, and the tensile strength is 31 per cent. greater, while ductility is not adversely affected. It suffers less from corrosion by sea water than ordinary mild steel or wrought iron; whence its fitness for use in propellers is evident. As a material for tires and axles it has many claims on our attention. It is well adapted as a material for shafting, and equally for railway axles, by the fact that a crack appearing in it will not develop as in carbon steel. As a material for castings much can be said in its favor. There are many other interesting points connected with nickel steel," but the facts already cited show that "it fulfills in a most satisfactory manner the conditions required of a material for shipbuilding and engineering purposes.

Experiments by E. D. Campbell and S. C. Babcock have brought out the fact that phosphorus, like carbon, is capable of existing in steel in at least two forms, and that the influence of phosphorus upon the physical properties of the steel in which it is contained is as much dependent upon the form of combination in which it exists as upon the quantity. This peculiarity of phosphorus, with the varying influence upon the brittleness of the steel ac
