is used in connection with the battery of gins having one large eon- 

 denser. In this system the weevils have no opportunity to escape 

 from the lint between the gin* and the baling apparatus. There fol- 

 lows naturally the suggestion that wherever possible the inclosed lint 

 flues should be used, thus allowing no avenue of escape for the weevils, 

 which must pass through the large condenser and there drop directly 

 into the press. 



SUGGESTED IMPROVEMENTS IN DEVICES FOR HANDLING AND 



GINNING COTTON. 



From the preceding accounts it will be seen that many of the devices 

 that have been perfected for cleaning cotton, and thereby improving 

 the sample, are incidentally of great value in eliminating the boll 

 weevil, although none of those tested have been found to be perfect. 

 The following recommendations look toward the modification of these 

 devices in such a way as to increase their efficiency. As the general 

 trend in cotton ginning is toward improving the sample, and as these 

 suggested modifications also accomplish that result, they should be 

 considered carefully by all ginners. 



IN THE SEED-COTTON STORAGE HOTJSE. 



At many of the smaller gins throughout the country the ginhouse and 

 seed-cotton storage houses are combined under one roof. This is the 

 case at 5i per cent of the ginneries in Texas and at Hi per cent of 

 those in Louisiana. Many of these buildings have no partitions, the 

 seed only being kept as far from the seed cotton as possible. Although 

 it is understood that in many cases it would not be possible for small 

 ginners to provide separate houses for storing the seed cotton and the 

 cotton seed, nevertheless in some cases it could be done without spe- 

 cial inconvenience. It is very evident that where weevils are present 

 the combination of the three houses under one roof is not advisable. 



Where the seed cotton is unloaded by hand directly from the wagons 

 into the storage house nothing can be done to destroy the weevils that 

 are brought in with the seed cotton except by the installation of one 

 of the various forms of separate cleaners or droppers. During the 

 latter part of the ginning season a great deal of seed cotton is handled 

 by hand, even at large ginneries, and does not pass through any 

 machinery in the seed-cotton storage house. In such cases it will be 

 necessary to pay particular attention to methods of eliminating the 

 weevil in the ginhouse proper by means of cleaner feeders, cotton 

 cleaners, separators, etc. In all seed-cotton warehouses where elevat- 

 ing pipes are used for receiving the cotton from the wagon and dis- 

 charging it directly into the room below, or for blowing the seed 

 cotton to different compartments, the most important feature is the
