It is, moreover, one which is subject to a number of serious plant diseases. Some of these, notably the late-blight, can be con trolled. By spraying. Yet this remedy is not applied by all farmers, and the annual loss amounts to many millions of dollars. Other dis eases, like dry-rot and the bacterial blight, are not controlled by spray ing and require a different line'of treatment. The subject of disease resistance in plants has received increased attention of late, and it is likely that the introduction of disease-resistant varieties of potatoes by supplementing spraying and special cultural practices, will be Of great practical value in lessening the Waste caused by disease. Although but little has been done in the United States toward secur ing varieties resistant to disease, the attention of potato specialists in other countries has already been directed toward this aim. AS a preliminary step in our work, Dr. L. R. Jones, botanist of the Vermont Agricultural Experiment Station, . Was commissioned to inquire into the occurrence of potato diseases abroad and the methods employed for their control, particularly with reference to the produc tion Of disease-resistant varieties. Doctor Jones spent six months from April to September, 1904 - in this work. In the course Of Doctor J ones's European itinerary, information of more or less value was secured at the following places, successively, and this was supplemented by a considerable correspondence covering a somewhat Wider area: Marseille, Naples, Florence, Munich, Halle, Berlin and vicinity, Dresden and vicinity, Bonn and vicinity, Wagen ingen (holland), Amsterdam and vicinity, Gron-ih gen, Delft, Gembloux (belgium), Paris and vicinity, London and vicinity, Reading, Cam bridge, and Edinburgh and vicinity. The thanks of the Department are accorded to the various Officials and other botanists in the coun tries visited, whose uniform courtesies made possible the success Of the mission.
