they roamed or ranged in multitudes across the new land? 

 Only the thicker settling of the country can affect the Arthro- 

 pods, but I think we are on the straight road to this result. 



It is now too late, but we are beginning to understand the 

 results of forest destruction. How greatly does it affect the 

 climate ! Or rather, the earth deprived of its covering becomes 

 dried out, so that it is unable to withstand the natural droughts. 

 So it appears to us that there is less rain. In other words, 

 we think the weather has changed. I, for one, do not believe 

 that it seriously changes the prescribed routine. The trees, 

 however, are a great preservative of the earth's crust. 'Hold- 

 ing it much more firmly together they prevent terrible wash- 

 outs at different seasons. 



All creations were placed here for some good, not to be 

 killed in a few years. The animal, vegetable and mineral 

 kingdoms balance each other. When one portion or the other 

 is destroyed in vast quantities the others are unbalanced, and 

 thus the dependent ones also perish or change their food. 



What right has man to be the judge? The results of his 

 endeavors, as seen throughout the world, are mostly mean and 

 unprincipled. Far better leave these things to nature, for 

 she alone can make and solve her own problems. 



Economic Notes on Aphids and Coccinellids. 



By ROSWELL H. JOHNSON, Cold Spring Harbor, New York. 



An experimental study of evolution in Coccinellids, such as 

 I am engaged in, necessitates a thorough survey of the vicinity 

 for aphids, in order that Coccinellids may be there collected 

 and food furnished them. There naturally results a consider- 

 able amount of data not pertinent to my subject, but yet of 

 value to economic entomology, which I wish to submit, even 

 though it be fragmentary. 



I have found aphids on the following plants in the vicinity 

 of Cold Spring Harbor, Long Island, which I have not seen 

 recorded from eastern North America : 



Acalypha virginica L. (upon the roots). 



Arctium minus Schk.
