One reason why Horticulture and the kindred sciences have not, heretofore, been taught in our common schools, may lie in the fact that we have not had suitable text books to favor the object. But times are changing, - wise men are growing wiser, and are coming to the conclusion that knowledge does not admit of monopoly, but her store-house is open to all who will enter in to secure its treasures. It is, therefore, no longer thought important, that science should be locked up in technicalities, that it requires years of the best portion of one's life to understand. No, our wiser and better men now study simplicity, and bring their knowledge within the comprehension of all: we have this fact happily illustrated in a recent work on Botany, by Prof.- Gray of Cambridge, who, as authority in the science, is second to no one. Premising that all intelligent cultivators will admit that the knowledge of plants is a very important knowledge to every cultivator of the soil, and a very pleasant study for the minds of the old as well as the young, his "How plants grow" probably contains more facts pleasantly narrated on the subject, than any other work extant, and they are just such facts as will tend to make the labors of plant growers pleasant and successful.

It is just the book for the common school, or the common reader. His "Lessons in Botany" is written in the same understandable style, and is followed by the structural and systematic Botany, and this again by his Manual: - the whole making a beautiful series on a highly useful and attractive science, adapted to the capacities of all. We shall hope for its intro-duction into farmers' families and common schools as fast as the publishers can furnish copies.

Geology and its kindred science Mineralogy have very much to do with terra culture, besides furnishing rich pasturage to the mind while engaged in cultural pursuits. In our country, it is comparatively a new science, scarcely known in our colleges a half century ago. Its growth, however, from the healthful aliment that has been given it, has been rapid in extent, and beautiful in symmetry.

Elementary Geology, by Prof. Hitchcock, is a beautifully illustrated work, admirably adapted to the capacities of the young, and probably contains more geologic facts, condensed from the author's personal observation, and collected from the best observers in all countries, than any other work extant, - written in so attractiye a style, that when we take up the book we don't know how to leave it. It is well adapted to the family and school-room.

In the introduction of foreign plants, great losses have no doubt arisen in consequence of the ignorance of the cultivator of the geological formations and physical features generally, of the localities from which they are brought. We have long wished to see some work on this subject, wherein the young might gain such information, and have at last been gratified to a large extent by the appearance of Fitch's Physical Geography, - which, for a work of its size has very much to commend it as a general school-book. All students, in descriptive geography, will see the importance of connecting the physical, and for young horticulturists it contains a host of facts of a practical nature. The above works are all got up in good style, at cheap prices, and may be procured by giving an order to any bookseller; we wish they were universally known instead of the foolish literature that is introduced, one hardly knows by what processes, into most families in the country.
