In compliance with what seems to be a wide-spread desire on the part of the geologists of America, a few have united in an effort to establish an American journal devoted to geology and its allied sciences.

The organization which issues and sustains THE AMERICAN GEOLOGIST is bound to maintain a creditable journal for at least one year, and to issue twelve numbers of at least fifty-six octavo pages each. Hence any person who has any sympathy with the enterprise need not hesitate to subscribe for one year through fear that the outcome will not be sufficient to produce a volume. The contributions of a single year will, when bound in a volume, be well worth the subscription price to any geologist, whether he be practical or professional.

THE AMERICAN GEOLOGIST will be devoted to geology in its widest sense, and to the interests of American geologists. It will include, therefore, within the scope of its discussions and contributions, all the sciences that are kindred, and that contribute, by their more special investigations, to the general science of geology. It will hence serve as a medium of intelligence to the stratigrapher, the petrographer, the paleontologist, the mineralogist, the fossil botanist, the climatologist, the chemist, the physicist, the seismologist, the glacialist, the anthropologist and the astronomer in all those directions where their special investigations bear directly upon the constitution and history of the globe. Geology includes them all, and is built upon them.

as cornerstones.

The GEOLOGIST will also make a special effort to aid the teaching scientist. Here is a felt desideratum in American scientific literature. A loud cry for help is going out from the teaching profession. Information is wanted as to how, what
