■was noted in Farmers' Bulletin 189 of this Department, it will be seen 

 that the general advantage of the early maturing varieties over the 

 late maturing ones is again demonstrated. During that season the 

 Herndon variety turned out to be the most prolific. This variety was 

 not tested during the season of 1904, for the reason that it was impos- 

 sible to procure seed. It was a local variety known in only one county 

 in Mississippi, and seems to have died out on account of the general 

 desire of planters for varieties which have large bolls. 



In reality the superiority of the early maturing varieties would 1)e 

 more in evidence than the following grouping would indicate. In 

 arranging the planting of varieties in the field the earlier ones were 

 placed nearest the timber. It was designed to have the varieties 

 graded from the vicinity of the timber according to their relative 

 earliness. Consequently the King variety was nearest the timber, and 

 the Russell most removed. As is usual in such cases, the weevils 

 appeared in the cotton near the timber first. For two wrecks before 

 an}^ of the pests had appeared in the middle of the field they were 

 causing consideraljle damage in the plats nearest the timber. 



It is not possi))le to give varieties of cotton a complete test during a 

 single season. The only correct basis for an estimation of the value 

 of different varieties in weevil-infested regions is a repetition ' of 

 experiments during several seasons. As has repeatedly' been found to 

 be the case in the tests of varieties of cotton which have been con- 

 ducted by southern experiment stations, the changing climatic condi- 

 tions alter the relative standing of the varieties ver}^ materially. In 

 some cases a variety found during one season to be at the head of the 

 list in production may, during the following season, fall far below. 

 Work that has been conducted elsewhere in Texas indicates some prob- 

 able modifications of general conclusions that might be drawn from 

 this test. For instance, the liowden variety would probaljly rank con- 

 siderably higher than was the case in these experiments. Neverthe- 

 less, it is believed that the test conducted by the Bureau of Entomology 

 in Robertson County will furnish the basis for a general idea of the 

 value of some of the principal known varieties. 



The lint from the varieties was given commercial grading as speci- 

 fied in the accompanying table, b}' a special committee of members of 

 the Galveston cotton exchange, appointed at the suggestion of the 

 writer by the president of the exchange. 



The name "Georgia Truitt"' applies to the seed of the well-known 

 Truitt variety from Georgia. The name "Texas Truitt" is used to 

 differentiate the cotton grown from Truitt seed which had been planted 

 in Texas for one year. The same distinction applies to the names 

 "King'"' and "Texas King."
