1899] CURRENT LITERATURE 145 
worker and the investigator in field, garden, or greenhouse, felt the need of 
some reliable work dealing in a plain way with the principles and practice 
involved in economical plant feeding. Such a work has been supplied by 
Professor Voorhees,’ who has the happy faculty of telling what one wants to 
know, and telling it briefly. One is told what to do and given a reason for 
doing it, and due consideration is given to modifications required by special 
or unusual conditions, 
The description of fertilizing material is up to date, and the formulas 
recommended for special crops are those that have been profitable in actual 
use; not the oft-reprinted ones that can be traced back only to advertising 
matter. 
In addition to the specific information in regard to feeding plants, the 
botanist will doubtless welcome the clear, brief summary of the several 
broad systems of fertilization that have been proposed and advocated at great 
length by their authors, 
The author is too genial to be accused of being a philosopher; but here 
and there he drops a remark that sets one to thinking of the broad questions 
iit in the production of plants, and then speedily leads one to see how 
the principles discussed can be reasonably and profitably applied. 
The book will receive a hearty welcome from both investigator and farmer.
