474 BOTANICAL GAZETTE [JUNE 
Two criticisms may be made upon the work asa whole. First, its bulk 
is rather unfortunate, for doubtless many who would be glad to get at the 
general results will hesitate to read so large a book. Second, it would have 
been a great convenience had it been indexed. These are minor criticisms, 
however, for the work is a most important and valuable one. It should per- 
haps be mentioned that, while this work on the Illinois River was planned 
and carried out by Dr. Kofoid, it may, after all, be considered as the direct 
outcome of work which has been carried on by the director of the laboratory, 
Dr. S. A. Forbes, for the past generation—C. DwiGHT MARSH.
