INSPECTION OUTSIDE THE REGULATED AREAS 
Inspections during the 1932 crop season were the most extensive on record, and, 
considering the negative results, together with the necessity for economy he- 
cause of reduced appropriations, it was decided to concentrate the inspections 
of the 1933 crop in those areas most under suspicion. As in past seasons gin-t ash 
inspection was begun in Texas in the lower Rio Grande Valley, and the inspectors 
operating the machines worked northward as the crop advanced. Machines were 
also used in Mississippi, Alabama, and South Carolina, and outside the regulated 
areas in Florida and Georgia. Some inspections were also carried on in the border 
States of Mexico, most of this being confined to the areas opposite the Rio Grande 
Valley of Texas. Except in the Juarez Valley of Mexico the results of all such 
inspections were negative. After the ginning season had ended, laboratory 
inspection of green boll and bollie samples collected in various cotton States was 
begun. This work had not been completed at the close of the fiscal year, but 
thus far the results have been negative. 
The amount of each class of material inspected and the State from which it 
came is shown in table 7.

CHANGES IN REGULATIONS 
During the fiscal year 1934 three changes were made in the pink bollworm 
quarantine regulations. The first change, effective September 19, 1933, was a 
revision of the regulations. Under this revision no essential changes were made 
in the means of control and the prevention of spread of the pink bollworm, but 
there was considerable rearrangement of the regulations in the interest of clarity 
and to facilitate administration. The regulated areas were divided into heavily 
infested and lightly infested areas. 
Effective October 24, 1933, the regulations were amended for the purpose of 
adding Gaines County, Tex., to the regulated area. 
Effective December 23, 1933, the regulations were again revised for the purpose 
of adding the newly infested sections of Florida, Georgia, New Mexico, and 
Texas to the regulated areas. The revision incorporated the amendment is-m-,1 
on October 24, 1933. At the same time the Salt River Valley of Arizona was 
released from regulation. At present the regulated areas include 3 counties in 
southern Arizona, 7 in north-cent ral Florida, parts of 3 in southern Georgia, 
9 in southern New Mexico, and 1 5 entire counties and parts of 3 additional ones in 
Western Texas. Of this area 5 counties and part of another in Texas were 
designated as heavily infested, and all the remaining area as Lightly infested. 
NEW MACHINES 
In past seasons it has not been practicable or economical to operate the gin- 
trash machines at isolated gins and at others where the output of tra-h is quite 
small. Therefore, during the summer of L933 a -mall gin-trash machine ua- 
developed which embodies the same principles of separating worms from trash 
as does the Large machine, power being supplied by turning a crank b\ hand. 
The machine weighs about 75 pounds and is so built that it can be placed in an 
enclosed light delivery truck, making it possible for one inspector to operate
