The Useful Trees of Northern Nigeria. By H. V. Lely.

(Crown-Agents for the Colonies. 10s.) This octavo volume of one-hundred and twenty-seven pages and the same number of illustrations, while not of interest to the general reader, is a thorough and careful piece of work, and of interest both to botanists, and to those engaged in the development of overseas timber and forest products.
