 National Waterways Commission, in 

 which the author has sought to assemble 

 all the well established scientific facts in 

 regard to the relation of forest to water 

 supply, will be of great value to the 

 student of these problems. The statement 

 of what is already definitely known serves 

 to show where future problems lie. Of 

 especial usefulness is the bibliography 

 covering 36 pages at the end of the paper.

 By E. J. Gilbert. Librairie E. le Francois

 This is the first volume of a proposed 

 series Les Livres du Mycologue. It is a 

 thorough discussion of the morphology 

 of the spores of mushrooms, and their 

 taxonomic significance. Its usefulness 

 would have been greatly enhanced if it 

 had been more adequately illustrated. 

 In the whole book there is but one plate 

 containing 14 line drawings. Except for 

 this defect it is an excellent piece of work.
