Pink Bollworm Field Work. 
The destruction and clean-up of cotton in and surrounding the districts 
ain Texas invaded by the pink bollworm is now practically completed for the crop 
| of 1917. The following summary of this work is condensed from a report prepared 
Mby Mr, F. S. Puckett for Dr. Hunter: 
| A total of 8794 acres of cotton land has been cleaned of standing and 
|) Scattered cotton at an average cost of $9.94 per acre. 
| The cotton fields cleaned represent 657 ownors or tenants or an avcrago of 
§13.38 acres to each owmmer or tenant. Most of the fields consisted of from one 
‘to one-half dozen acres and only in a few instances did the fields approach or 
€xceed one hundred acres. 
. In addition to the clean-up of these cotton fields within and surrounding 
(@ehe known infested areas, all the gins in this section, some twenty in number , 
Thave also been subjected to a thorough cleaning, with destruction of remaining 
‘and scattered seeds. 
An effort has also been made which has been substantially successful to 
collect and mill under supervision all cotton seed grown in this section, and 
the lint cotton has been shipped to foreign countries via Galveston. These 
Several steps have eliminated so far as is now possible tho chanco of over= 
wintering and reinfestation of the new crop by the pink bollworm hibernating in 
‘the cotton fields or in cotton seed or in lint cotton of the crop of AS ay |S
