By Chas. F. Wheeler and Erwin F. Smith. Published by the authors at Hubbardston, Mich. Price, 50 cents.

This interesting catalogue, prepared for the Pomological Society's report, has been issued separately by the authors, at a price that will barely pay for the cost of getting it out, leaving the work of preparation - the labor of many years - to use a trite but very expressive phrase, a labor of love. These lists are of immense value to students in the States the lists cover, and to others everywhere who study geographical botany, and we have no doubt those so interested will feel grateful to these botanists for what they have done for them.
