RESULTS OF COTTON EXPERIMENTS IN 1911. 5 



riant o;rowth and IVuits abuiulantly. The Lone Star also has less 

 tendency than the Triumph to shorten the lower fruiting branches. 

 Another short-staple variety called Trice was bred by Prof. S. M. 

 Bain, of the Tennessee Agricull ural Experiment Station, in coopera- 

 tion with the Bureau of Plant Industry. The Trice cotton is becoming 

 po])ular in western Tennessee and the demand is also spreading in the 

 adjacent regions of northern Mississippi, Arkansas, and Missouri. 

 This variety w^as obtained by selection from a local stock known as 

 Tennessee Green Seed. The Trice is an extra-early variety, more 

 prolific than King, with larger bolls and better lint. It is much 

 superior to the unselected stocks that are being grown in western 

 Tennessee and is preferable to King and other eastern short-staple 

 varieties that have been carried west as a means of securing protection 

 against the boll w^eevil. But the Columbia and other long-staple 

 varieties of cotton are also giving good results in western Tennessee, 

 where the conditions seem to favor the production of fiber of good 

 quality. 



ACCLIMATIZATION OF TROPICAL VARIETIES OF UPLAND COTTON. 



As a result of agricultural explorations made several years ago in 

 weevil-mfested regions of Mexico and Central America several new 

 types of Upland cotton were introduced to test the possibility of 

 their acclimatization m the United States. Some of the introduced 

 varieties behaved in a very abnormal manner when first planted in 

 the United States, becoming very much overgro^\^l and unproductive 

 and showing great diversity, but they have now returned to their 

 normal characteristics as early and prolific members of the Upland 

 series. Uniform strains are being bred from bidividual plants 

 selected as the best representatives of their types. Four of the 

 imported types, Kekchi, Durango, Acala, and Tuxtla, prove to have 

 important points of superiority over any of our United States varie- 

 ties of Upland cotton. 



In addition to certain speciahzed characters that afford some pro- 

 tection against the boll weevil, the new sorts have very abundant 

 lint of excellent quality and of good length, ranging from 1 to 1\ 

 inches. The bolls are larger than in American Upland varieties 

 that produce as long a fiber. Two of the new types, Durango and 

 Acala, seem to be specially adapted to conditions of dry farming and 

 irrigation in the Southwestern States. These types have been 

 grown in field plantmgs with excellent results. Still larger plantings 

 are to be made in the coming season to test the behavior of the varie- 

 ties under different conditions and to secure seed for more general 

 distribution. The Acala type promises to become useful for general
