JMe7/ 
States Department of Agriculture at Caribou, in northern Maine, 
and of Dr. W, A. Orton, plant pathologist of the Bureau of 
Plant Industry, the writer recently had the pleasure of joining in 
a potato study trip through New England. The party consisted 
of a group of plant pathologists and others interested in potato 
culture, headed by Dr. Orton and by the acting chief of the 
Bureau, Professor Corbett. As a special guest of the United 
States Department of Agriculture, the party was accompanied by 
Geheimrat Dr. O. Appel, of the Imperial Biological Institute for 
Agriculture and Forestry, at Berlin-Dahlem, the leading authority 
on potato diseases in Europe; and also by Dr. H. T. Gttssow, the 
Dominion botanist of Canada, whose discovery of a serious potato 
disease in Canada precipitated the recent quarantine activities 
against the entry of dangerous insect and fungous pests into the 
United States. 
The itinerary of the main party, beginning with visits to the 
truck growing districts in New Jersey on July 28-29, was planned 
to extend through the larger potato growing regions ia Rhode 
Island, Maine, New York, Michigan, Wisconsin, Minnesota, Colo- 
rado, Utah, Idaho, Washington, Oregon, and California, lasting 
until about October 1. This party was to be joined at intervals 
by specialists, from State Experiment Stations and elsewhere, 
who were primarily interested in investigations of the disease, 
breeding, culture, or related phases of the potato industry. 
The writer joined the party, then including only half a dozen, 
at the State Experiment Station at Kingston, Rhode Island, on 
the morning of July 30. Here, besides inspecting under the 
guidance of Professors Damon and Pember, the varietal tests of 
potatoes, and studying the diseases present in the plots, I accom- 
panied Mr. F. V. Coville, of the Bureau of Plant Industry, in his 
inspection of blue-berry culture experiments, being carried on at 
the station farm in cooperation with the Bureau. 
On arrival at Caribou, Maine, on the morning of July 31, the 
party was augmented by a considerable number of plant patholo- 
gists, inspectors and others interested in potato culture, about ten 
of whom were connected with the government laboratory at 
Caribou, and others from the Maine and Vermont State De- 
partments of Agriculture, from the Maine Agricultural Experi-
