[Introduction to address before the eastern New York horticultural 
society] (Country gentleman, 2 Mar. 1899, 64: 17474) 
The extension of the upper austral life zone along the Hudson river, and 
the unexcelled facilities of the stream for the transportation of insects, render 
this region very interesting and a study of its fauna of great importance. 
Isolation of orchards is recommended wherever practicable. A few observa- 
tions on the San José scale are given. 
Injurious shade tree insects, with special reference to the elm leaf beetle. 
Address before the Troy scientific association, 6 Mar. 1899. (Portion 
published in the Troy times, 7 Mar. se) Also in Argus [Albany] 
12 Mar. 1899, p. 9) 
After the work of the elm borer, Saperda tridentata Oliv., and the 
elm bark louse, Gossyparia ulmi Geoff., is briefly characterized, the 
elm leaf beetle, Galerucella luteola Miill., is treated under the follow- 
ing heads: injuries, life history and habits, ineffectual measures, spraying with 
poison, importance of thorough work, approximate cost and the necessity of 
municipal action.
