SOUTH CAROLINA, 195 



the plantings are beginning to make a good showing. The mailing 

 list of the station now includes about 18,000 names of farmers of the 

 State. The legislature authorized the location of two additional 

 substations and provided fimds for their maintenance. 



The work during the year on the several Adams fund projects was 

 generally progressive. The horticulturist continued the study of the 

 Rotundifolia grapes, giving special attention to self-sterility and the 

 possibility of determining bisexuality in some of the varieties. For 

 the purposes of this work over 150 seedlings were set out in the fiew 

 horticultural grounds, but much of the study was conducted with 

 older vines on the college grounds. 



Pot work on the relation between transpiration and the amount of 

 nitrates in the soil was begim in the greenhouse and supplemented 

 with field experiments. In connection with this project a study of 

 the morphology of corn as influenced by depth of planting and by 

 nitrate of soda was made. The past year was the fourth in which 

 experiments were conducted to determine the effect of pollen from 

 barren stalks on the yield of corn. It did not appear that the corn 

 decreased in yield from year to year, but it seemed that the pollen 

 from the barren stalks affected the position of the ear on the stalk. 

 In the study of the relation of soil type to length of cotton fiber, the 

 importance of seasonal influence was clearly brought out. In 1910 

 the longest, finest, and most uniform fiber came from clay soils which 

 contained some fine silt. Incidental to this investigation it was 

 found that big-boll types of cotton are best adapted to sandy soils in 

 South Carolina. 



The department of plant pathology devoted most of its time to 

 the study of cotton anthracnose, giving special attention to a study 

 of the means by which the fungus passes from crop to crop and 

 from plant to plant during the season. Spores within the seed and 

 adhering to the lint seemed to be the principal means of carrying 

 the fungus from crop to crop. It is believed that by selection of 

 clean seed in the field and by planting on clean land the disease can 

 be eliminated in a single season. A special study of the detection 

 of anthracnose in cotton seed was made, and the centrifuge method 

 was adopted for the accurate determination of the amount of an- 

 thracnose on the outside of the seed. It was found that where the 

 disease was in the seed it always appeared on the seedlings. 



The chemist devoted much time to work on the cottonseed -meal 

 poisoning project. He made ether, alcohol, and water extracts for 

 use in feeding experiments, nearly 400 pounds of cottonseed meal 

 being extracted. Differences in the phosphoric-acid content of seed 

 grown at the coast substation, representing the lowlands, and of 

 seed produced at the Clemson station, which represents the higher 

 altitudes in the State, were observed. Of the cottonseed meal, the
