weevil 
Since the last Monthly Letter wes issued, a new sveet-potato/district 
has been discovered in the Stute of Mississifpi, embracing about fifteen 
infested propertics sast of Ocean Springs, along the line of the Southern 
Railway, probably caused by the shipment of swept-potato plants from the 
infested section in Louisiana. 
It is worthy of note that the sveet potat® crop, =ccording to stat- 
istics punlished in the Decerber issue of the Monthly Crop Reporter of 
the Departuent of Agriculture, is greater in vehue by atonut $20,000,000 
than that of last yeur. The six Gulf States in which infestations of the 
sweet-potato weevil have been noted produce more than 50 per cent of the 
crop for the United States. 
W.H, Carpenter has been appointed field assistant in insect control 
and ussigened to the irrortant work of eradication o£ this rest under the 
direction of 4%,L. Cockerhan,.
