"e;Not only do we need to know what agriculture is, but the relative importance of its parts"e;. The Principles of Agriculture is an extensively comprehensive handbook covering absolutely everything necessary for success in agriculture, written by one of the most knowledgeable practitioners of his time: Liberty Hyde Bailey. This text starts by outlining the intrinsic roles of science and business in agriculture, going on in a logical order to set forth the skeleton of the subject to be used by a teacher in agricultural education. A seminal piece on agriculture, this scarce text will appeal to those interested in the evolution of modern agriculture and constitutes a must-have for collectors of Bailey's work. American-born Liberty Hyde Bailey was a prolific horticulturist and botanist who wrote extensively on both topics. Originally published in 1897, we now proudly republish this scarce classic with an additional biography of the author.
