446 ANNUAL REPORTS OF DEPARTMENT OP AGRICULTURE. 



The infested area is more or less isolated, and the growth of 

 potatoes is in gardens for local use. There is no commercial growth 

 of potatoes in the district and therefore little likelihood of any com- 

 mercial or other shipments of potatoes out of the district. 



Under the leadership of Economic Zoologist J. G. Sanders the 

 Pennsylvania State authorities are taking necessary restrictive meas- 

 ures to prevent infected material from moving out of the district. 



It is rather to be feared that other shipments of European potatoes, 

 made prior to the quarantine, have carried the disease to other dis- 

 tricts, and a counttry-wide examination of gardens of industrial and 

 mining villages, which were the principal markets for cheap foreign 

 potatoes, is being made. This disease has certainly not developed in 

 any of the important potato-producing sections of this country.
