strength to crush all of the weevils that might be contained. After that 

 has been done it would be immaterial whether the debris was scattered 

 about the gin yard or sent with the seed to the seed-storage house. 

 The installation of the compression rollers would, therefore, not inter- 

 fere with the trash taking exactly the same course as it does at the 

 present time. It should be noticed in this connection that the very 

 important point is in having the spiral conveyor continuous with the 

 whole battery of gins and ha\'ing only one outlet. With some of the 

 cleaner feeders there are separate screw trash conveyors for each 

 stand, situated under the front of the feeder. In such cases it would 

 be necessar}^ to carry the trash from the pipes that are generally pro- 

 vided into one continuous conveyor discharging at one end, where 

 compression rollers could be applied in the manner that has been 

 mentioned. 



With the belt-distributor system, it will be necessary to provide a 

 box for the overflow of seed cotton. If the seed cotton is scattered 

 over the floor, the weevils can escape more freely than if dropped into 

 this box. A better method, however, would be to provide, in connec- 

 tion with the separator and vacuum box, a complete cotton cleaner and 

 separator combined. Thus the seed cotton would be practically freed 

 from weevils before it is dropped upon the distributor belt. 



With the present huller gins and plain feeders, the boll weevil is 

 kept under less control than with plain gins. All live boll weevils which 

 become loosened from the seed cotton while on the feeder roller neces- 

 sarily fall down into the seed conveyor and pass out with the seed; 

 with the plain gin, on the other hand, the seed cotton is fed directly 

 into the breast or roller box of the gin, thus coming in contact with 

 the saws immediately. However, this apparent objection to the 

 huller gin could be entirely obviated by the placing of a cleaner feeder 

 above the stand. 



With the plain feeders now used the boll weevils are kept much 

 less under control than with the modern cleaning feeders. The seed 

 cotton is dropped upon an endless apron and conveyed against the 

 picker roller, which separates the locks, elevates them, and deposits 

 them directly in the gin breast. Hence all weevils not carried up and 

 deposited directly in the gin breast, or with the huller gins in the 

 outer breast, drop through the full width of this endless apron feeder 

 upon the top of the gin stands and are there scattered in all directions. 

 A practical suggestion concerning the elimination of this difficulty is 

 in the attachment of a movable bottom sheet beneath the apron 

 wherever this would not interfere with the operation of the gin. In 

 some cases there might be difficulty on account of the small space 

 between the revolving apron and the top of the stand. However, 

 wherever a false bottom could be used, all of the trash, including the
