indicated on a number of occasions, there is a strong and insistent 
demand upon us for the development in our pupils of a realiza- 
tion of their obligations to the community; and, to an extent, of 
a proper realization of the social and economic environment in 
which they live. Furthermore, there is a strong and insistent de- 
mand that we devote more and more time to the development of 
the physical well-being of our high school students. All these 
things, namely, the.call for a course in general science, the call 
for a course in the study of the social and economic environment 
of the child, the call for the physical development of the child, 
indicate that biology will ultimately have to give way.”’—Arthur

CONFERENCE ON POTATO DISEASES ON LONG 
ISL 
An important meeting of potato pathologists was held on Long 
Island during the week of June 24-28. Potato growing is one of 
the most important and extensive industries of the Island, and 
here, as elsewhere in potato growing, eternal vigilance and strict 
attention to the advice of plant disease experts, or “plant doc- 
tors,” is the indispensable condition for a successful crop. There 
are a score or more of diseases to which potatoes are susceptible, 
and this conference was specially devoted to the so-called “ de- 
generation diseases,” mosaic disease, leaf-roll, and curly dwarf. 
The meetings of June 24-25 were at Riverhead, L. I., and nearby 
farms and gardens. 
Specialists were in attendance from the Federal Horticultural 
Board of the United States Department of Agriculture, and from 
agricultural colleges and experiment stations of various states. 
Foreign specialists include Dr. H. M. Quanjer, of Wageningen, 
Holland; Dr. A. D. Cotton, of the Royal Botanic Gardens, Kew, 
England, and Dr. George H. Pethybridge, Pathologist, Royal 
College of Science, Dublin, Ireland, and Mr. P. A. Murphy, Char- 
lottetown, P. E. I. 
The potato disease projects are under the general supervision 
of the following Advisory Board: Leaf roll disease, Mr. P. A.
