Golden apples grafted on strong, medium, and weak stocks, and also 

 of scions from best and poorest bearing trees to determine the value 

 of the selection of scions based on the fruitf ulness of the parent stock. 

 Selection work with strawberries and tomatoes was in progress and 

 some experimental work in canning vegetables was undertaken. 

 Asparagus selections were made for size of stalk and resistance to 

 rust. An experiment on hardiness and phenology of northern and 

 southern peaches of the same varieties, as well as of a number of 

 species of native forest trees, was completed, and the results were 

 about read}^ for publication. The work was carried on for 10 years, 

 and all varieties had apparently attained a common phenology. 

 Considerable demonstration w^ork was done in peach and apple or- 

 chards of the State, and marked results demonstrating the value of 

 proper orchard management were secured. 



In plant pathology, investigations were made on the grain smuts 

 with special reference to the influence of temperature of smut in- 

 fection. In addition, a leaf spot of tomatoes having appeared in a 

 certain part of the State was studied. 



The entomologist of the station studied a number of insect pests 

 including bagworms, striped cucumber beetle, hickory-twig borer, 

 San Jose scale, chinch bug, the fall army worm, and other pests. 

 The work on bagAvorms and on the distribution of San Jose scale was 

 prepared for publication. 



The veterinarian continued work on tuberculosis, giving special 

 attention to testing the von Behring method of eradication. He also 

 studied the possibility of swine infection from cattle, and especially 

 how soon the infection may be recognized in pigs. The possibility 

 of conserving hog-cholera serum in a dried fonn was also investi- 

 gated. Under State funds active work was pursued in the produc- 

 tion of hog-cholera serum, for which at certain times there was 

 a great demand. 



The dairyman studied the effect of feeding cottonseed meal to 

 dairy stock, the influence of heavy and light feeding of heifers, and 

 early and late calving on the mature animal. The nutrients required 

 for milk production were studied and tlie data for five Jerseys Avere 

 completed and published in bulletin form. The experiment was 

 broadened to include Holsteins, Ayrshires, and Shorthorns, and the 

 work includes digestion experiments which run for a year for 

 each lot. 



The station carried on in numerous localities a large amount of 

 work supiDorted by State funds. This endeavor was mainly along 

 the line of demonstration work, although some experiments on soils, 

 alfalfa, selection and breeding of various grains, and testing new 

 varieties were carried out. In the Ozark Mountain region experi- 

 ments were conducted on the improvement of pastures with a view
