of nature in the culture and growth of crops, would elevate agriculture to a conspicuous rank among the exact sciences.

I hope that parents will be willing to introduce this brief Catechism into the Common Schools of this State.

S. YOUNG.

I have read with great pleasure and profit the condensed little Agricultural Catechism of Prof. James F. W. Johnston of Scotland. Like every production of his pen, it is characterized by a sound, practical good sense, which adds double value to his scientific labors, rendering them available to the very class for whom they are more especially designed-practical farmers.

I learned with pleasure from Prof. Johnston, that Mr. John P. Norton was about to edit, with an introduction, his Agricul tural Catechism. This American edition should be in every village school in the land, as being within the comprehension of all intelligent children; and it cannot indeed be too highly recommended to the attention of all classes of teachers, as the best synopsis yet made of the valuable facts and principles which have been established in the important science of agriculture. B. SILLIMAN, Jr.

I consider J. F. W. Johnston's Catechism of Agricultural Chemistry and Geology, to be extremely well adapted to the use of schools, and that it ought to be introduced as a text-book into all our rural districts where farming is the principal employment of the population. The time has come when agriculture is to be taught as a science as well as cultivated as an art, and a little book like this sheds more light on the nature of soils, the elementary principles of plants, and the food necessary for their growth and maturity, in a small compass, than any other publication I have ever seen. The youthful mind can easily be made to comprehend the principles it teaches, and we are wanting to our own and the great interests of our country, if at this time we do not do all in our power to create a taste and diffuse a knowledge of so important a pursuit.

J. P. BEEKMAN, Late President of N. Y. S. A. Society. Kinderhook, Jan. 22, 1845.

Having examined Professor Johnston's Catechism on Agricul. tural Chemistry and Geology. I most cordially unite in the recommendation of the work. Its introduction into our Common Schools, will form a new era in the education of our children. The time has arrived in which every proper effort should be

made to give such an education to the rising generation as will prepare them rightly to appreciate, as well as successfully to follow, the pursuits of Agriculture, for which most of them are designed. It will give me great pleasure to do all in my power to disseminate this little work, which I doubt not will produce the most happy effects throughout our country.

-From the Am. Quarterly Journal of Agriculture and Science. The reputation of this work is so well established, that it is hardly necessary at this late day to recommend it. It is certainly as useful to a large class of farmers as to the pupils in schools. It is plain, simple, and contains all the elements of agricultural chemistry; and as much of chemistry as this work contains, must be in his possession, if he would read the ordinary agricultural journals of the day.

Young men may take it into the field in their pockets, for instruction, while their teams are resting in the furrow.
