the American as the female parent. Some of the hybrid trees 

 have been attacked by the blight but others seem to be immune. 



The 1936 drought is one of the most serious and widespread 

 the nation has ever experienced. Not only have there been un- 

 told suffering by the local residents and terrific losses in crops, 

 but other forms of life over considerable areas are showing the 

 effects of abnormally high temperatures and deficient precipita- 

 tion. Just how serious some of these effects are remains to be 

 seen. 



As information on drought resistance of trees and shrubs is 

 sadly lacking, the present affords an unusual opportunity to 

 obtain data of outstanding value. Consequently, it is hoped that 

 those who are in a position to do so will take notes on the reac- 

 tion of various plants to the drought. 



The Forest Service is undertaking the collection of data on 

 the drought damage. In this it is seeking the aid of botanists, 

 and other interested individuals throughout the drought area. 

 Anyone with observations on species behavior should communi- 

 cate them to the Division of Silvics of the Forest Service at 

 Washington, D. C. Data are desired especially on such features 

 as the nature, extent, and character of the damage, the relative 

 resistance of trees growing on different sites, the comparative 

 ability of native and exotic trees to withstand drought and the 

 nature and extent of the damage to stands or to shade or orna- 

 mental trees, shrubs, etc. A questionnaire covering these points 

 has been drawn up to aid observers in reporting the effects of 

 the current drought. 



Boris A. Krukoff, of the New Yoi-k Botanical Garden, sailed 

 recently for Brazil, where he will continue his work on the poi- 

 sonous plants of the Amazon territory. (Science)
