Abstract

No teacher of agricultural chemistry can afford to do without Johnson's two books, “How Crops Grow,” and “How Crops Feed.” If he tries it, he will miss two most valuable sources of help for his lectures. The first was written in 1868, and instantly achieved a most remarkable popularity, being translated into French, German, Russian, Swedish, Italian, and Japanese, besides being revised and adapted for English readers by Church; the second appeared two years later, and was almost equally successful. Neither book is ever likely to get out of date, because each deals so fully with the fundamental experiments carried out by men who were laying the foundation of what has since become a great subject.
