done by some other insects, and even by shell-fish, such as the lobster and the crab. It was next changed into what is called an Au-re'lia or Chrys'alis, in which state it long continued without the least appearance of life, and for which it had pre' vi-ous-ly prepared itself a shelter and defence; ind, from that lifeless condition, it at length burst. forth in all its glory, the beautiful animal which you now so much admire. worm. There is one class of these animals, which is of the greatest service to man, I mean the silkBefore this caterpillar passes into the form of an aurelia, it weaves for itself a web, in which it may be safely entombed during its lifeless state; and it is from this very web, that we get all the silk which is used in making silk gowns, silk stockings, rib'ands, and many other of our most splendid and costly pieces of dress and furniture. Is it not strange to think, that the rich robes, which now deck the finest ladies, and the judges of our land, were once no other than the shroud, which wrapped a poor lifeless worm? you Let the changes, through which this wonderful animal passes, remind of those which ye your selves must undergo. Ye all, like the chrysalis must for a time lie shrouded in the tomb. But, from that tomb, ye also shall one day arise, and if ye "have done good," shall be transformed into a nobler being. Though ye lie down "in weakness he shall be raised in power;" though ye lie down "in dishonour, ye shall be raised in glory;" and, rising with far more ex-alt'ed fac'ul-ties, shall soar aloft to the bright re'gions of eternal day. When the last trumpet's awful voice When opening graves shall yield their charge, Those bodies, that corrupted fell, Shall incorrupted rise; And mortal forms shall spring to life, Immortal in the skies. QUESTIONS. What was the butterfly once? What was it called when it first came out of its egg ? What are the next changes which it undergoes? What is it called while it continues in an inactive and apparently lifeless state? Which class of these animals is of the greatest service to man? From what are all fine silk dresses made? What lesson should we learn from the changes which the caterpillar undergoes? COPPER AND BRASS. Copper is a metal of a red or reddish brown colour. It is ver'y malleable and duc'tile, so that a halfpenny might be rolled out, in the form of a wire, to the length of a long riband. It is lighter than silver, and of course much lighter than gold. It is one of those imperfect metals which are destroyed by fire, and are li'a-ble to rust. The rust of copper is a rank poi'son; and, for this reason, when cooking vessels are made of it, they should either be lined with tin, or the greatest care should be taken to keep them constantly clean, as fre'quent deaths have arisen from the ne-glect' of this precau'tion. All rust of copper is sometimes called ver'de-gris, but this name is generally confined to that particular species of it, which is produced by the action of the ac'id of grapes upon copper, and is used as a beautiful green paint. Besides being employed for kitchen purposes, such as pots, pans, kettles, &c. copper is also used for making cisterns, cauldrons, and other implements for brewing, dying, &c. The inferior kinds of money are made of it; such as our pence, halfpence, and farthings. It is employed to cover the bottoms of ships, in order to preserve them from rotting. And it is by means of copper plates, that the engraver is enabled to throw off as many impressions as he pleases, of the most beautiful pictures. Copper is very often mixed with other metals, not only as an alloy to render them ca'pa-ble of being wrought, but also for the purpose of producing, by means of the mixture, a substance more useful for a particular purpose, than either of the ingredients would have been separately. Thus, by mixing copper with about an eighth part of tin, a mixed metal is produced, called bronze, of which stat'ues are frequently made. When mixed with a little tin and another me-tallic substance called antimony, copper becomes gun-metal for the manufacture of cannons of a particular description; when a greater quantity of tin is added, it becomes bell-metal. Brass is a mixture of copper and another metallic substance called zinc. This mixture is more beautiful, harder, easier to melt, and less liable to rust, than copper. It does not, however, bear hammering well, and is therefore generally cast in a mould. It is much used for handles of locks, or of drawers, bell-pulls, candlesticks, lamps, mathematical instruments, clocks, pins, &c. Copper is found in many countries. There are various mines of it in our own i'sland, particularly in Wales and in Cornwall. QUESTIONS. What is the colour of copper? Whether is copper or silver lightest?

William and Ed'ward were clev'er little boys, and not at all ill-na'tured, but they were very fond of sport. and did not care whether people were hurt D o not, pro-vi'ded they got laughter. One fine summer's day, when they had said their lessons, they took a walk through the long grass in the meadows. William began to blow the dan-de-li'ons, and the feathered seeds flew in the wind like arrows; but Edward said, Let us tie the long grass over the path, that we may see people tumble upon their noses as they run along, without suspecting any thing of the matter. So they tied it in sev'er-al places, and then hid themselves to see who would pass. And pres'ent-ly a farmer's boy came trudging along, and down he tumbled, and lay sprawling on the ground; however, he had nothing to do but to rise again, and so there was no harm done this time. Then came Su'san the milk-maid, tripping along with her milk-pail upon her shoulder, and singing like a lark; when her foot struck against the place where the grass was tied, and down she came with her pail, and her milk was all spilled upon the ground. Then Edward said, Poor Susan! I think I should not like to be served so myself, let us untie the grass. No, no, said William, the milk is spilled, but there are pigs that will lick it up: let us have some more fun. I see a man hurrying along, as if he were running for a wa'ger; I am sure he will fall upon his nose. And so the man did; and William and Edward both laughed; but when the man did not rise again, they were sadly frightened, and, walking up to him, asked if he was hurt. O masters, said the man, some thoughtless boys, I |
