In most cases the length and strength of fiber of crossed plants 

 were greater than the length and strength of fiber of parent plants. 

 Plants which were strong and vigorous from the start and which grew 

 slowly from large and well-developed stalks gave fiber of the best qual- 

 ity. The proportion of lint to seed cotton was in most cases less with 

 the crossed plants than with the parents. The absolute amount of lint 

 per boll was, however, greater in the crosses than in the parent plants. 

 In most cases the size of seed was increased by crossing, a result prob 

 ably due to the fact that the female parents. Peerless and W. A. Cook, 

 are varieties with large seed. 



Properties of a well-formed cotton fiber (pp. 19-21). — The qualities 

 desired in a cotton fiber are (1) complete maturity throughout the entire 

 length, (2) uniform twist irom end to end, (3) uniform width in all parts, 

 (4) maximum length, and (5) iiurity in color. 



Tabulated data are given for each variety and for each cross regard 

 ing the length of branches; height of stalk; number of lobes per leaf; 

 number of bolls per limb; shape and measurements of boll; productive- 

 ness and time of maturity of jilant; character of the seed; length, 

 diameter, strength, and weight per boll of fiber; number of seeds i^er 

 boll; weight of seed; proportion of lint to seed cotton; and condition of 

 fiber with reference to twist and degree of maturity.
