Mr. W. D. Keyser, Marlin. 



These fields were visited on September 9 by Mr. G. H. Harris, who 

 reports as follows: Mr. Keyser had twice poisoned a 24:-acre block at 

 the rate of 2i pounds per acre. The adjoining nonpoisoned field ap- 

 peared to be equally well fruited, but no l)looms were seen in either 

 field. 



Another 20-acre field was poisoned twice with a half pound per acre 

 at each application. The adjoining field, though not poisoned, appeared 

 to be equally as good. 



In another field one part was poisoned twice with 1 pound per acre, 

 one part four times with 1^ pounds per acre, and the balance was not 

 poisoned. No diflference was found in the number of bolls or blooms 

 on the plants counted, and as man}'^ weevils were found in one part as 

 in another. 



The fact that Mr. Ke} sers crop is better this year than heretofore 

 is due to the fact that this year he has planted improved seed — King 

 and Indian Territory mainly. Other near-by fields were seen which, 

 while not poisoned, were as good or even better than Mr. Keyser's 

 poisoned fields. 



Rev. J. M. Purcell, Lockhart. 



All of the cotton used in the following experiments was planted in 

 rows 40 inches apart, with plants 2 feet apart in the drill. All fields 

 were plowed four times. All were poisoned four times b}" means of a 

 powder gun at intervals of ten days. The first application was made 

 on July 18 and the rates of application were 2, 2, 2, and 6 pounds per 

 acre. Each of the four experiments had an adequate check. In two 

 of the tests the poison was applied earl}- in the morning while the 

 plants were still wet with dew, and in the other two the poison was 

 put on after the plants had become entirely dr}'^, the theor\^ being that 

 the poison would enter the involucres of the bolls and squares. 



The first field, about 2^ acres in area, was located on a hillside and 

 the part poisoned Avas a triangular piece of one-half acre. This field 

 was planted earl}^ in March with native seed, but replanted after being 

 cut down by hail on May 16. To this field the poison was applied 

 while the plants were dry and the yield was nearly 700 pounds of seed 

 cotton, while the check produced almost nothing. 



All of the following fields were entirel}'^ cut down by the hail on 

 May 16 and were replanted with common native seed about May 30. 

 The cotton was about waist high when first poisoned. 



The second field was located on bottom land with woods and creek on 

 two sides, the land sloping upward and away from the creek to the 

 northward and at this end of the field was the check; the southern 

 end of the field was 1 acre in area and was poisoned when the plants
