By James Mills, President, and Thomas Shaw, Professor of Agriculture in the Ontario Agricultural College. Pp. 250. Illustrated. Toronto: The J. E. Bryant Co. This is an admirable book. It is designed for use in the "third and fourth classes" of the Ontario public schools. It contains more of the gist of agriculture and less of irrelevant and abstruse matter than any book of twice the size which we have seen. It is particularly admirable in its definitions and methods. It is pruned of wordiness. Its sub-heads and correlative statements are logical in arrangement and direct in application. Succinct reasons and advantages of certain practices are given throughout the book, of which the following "points of merit in plowing" may be taken as a random example:

"1. A straight furrow of uniform depth and width.

"2. A clean cut as to the furrow, both on the side next the unplowed land and on the floor or bottom ; and hence, correspondingly clean cuts on the exposed edge and top of the inverted slice.

"3. The complete burial of the grass and stubble turned over.

"4. A ridge even and uniform, with a finish showing an open furrow with a clean, narrow bottom. The last furrow-slice should be about equal in width and height with the others".

The book deals with general farm science and practice, farm crops, feeding and breeding of animals, dairy-ing, silos, etc. Its method is eminently adapted to schools, and it must prove very useful in them if seriously introduced. And to everyone on a farm it presents the best series of definitions and the objects sought by common operations of any book we have ever seen. The mechanical execution is unusually good.
