By Prof. Beal, Professor of Botany and Forestry in Michigan Agricultural College. Published by the author, at Lansing, Mich.

There may have been a work on grasses equal to this in value, in the Old World or somewhere, but if there ever has been, it has escaped the writer's attention. It is wholly an original work - a point that is full of meaning, when we remember the high reputation of the practical man of science who writes it. It proposes to cover the whole range of intelligence relating to grasses. We have chapters on the physiology of grasses, their chemical composition, selection, improving, cultivation, management of grass lands - and, as clover has very much to do with grass lands, this also is embraced. The doings of insects, fungi, etc., are also shown up, and it is difficult for any one to conceive of a topic in connection with grasses on which he may not be enlightened by a perusal of this volume. If all flesh is grass, surely all men will be interested in the work - and in some aspect or another this is literally true. Prof. Beal has done a great work for our country in giving them this.

This one volume will not, however, yet satisfy " all men," for the feast for the botanist is yet to come. The list of all the seven hundred known grasses of North America, botanically described and classified, is yet to appear. But this will make no difference to the completeness of Vol. I. This will be just as useful to the mass of mankind, though the second volume should never come. It is a large octavo of 457 pages - and is full of excellent illustrations, many drawn by that excellent grass-man, F. Lamson Scribner.
