were made, and experiments were pursued in the improvement of 

 blue grass by selection. Studies were also conducted on the effect of 

 growing white clover Avith blue grass and of beans with corn, in rela- 

 tion to the nitrogen content. 



In studying the relation of parasitic fungi and bacteria to their 

 host plants, work was continued to determine the toxic agents causing 

 decay. Work was also followed on the action of enzyms, the influence 

 of the presence and absence of oxidase and peroxidase, the assimila- 

 tion of carbon dioxid of diseased leaves, and the physiological action 

 of the parasitic organism on the foliage. 



A number of other lines of work were carried on in addition to the 

 Adams fund investigations. The horticulturist began an experiment 

 on the relation of nitrogenous fertilizers to pear blight, alwut 150 

 trees, some grown in sod and others in clean culture, being under ob- 

 servation. Hybridization work with cabbage was conducted in the 

 greenhouse to study the transmission of the qualities and the manner 

 of inheritance and the origination of new types. A new orchard of 

 apples and peaches, set out to furnish material for the fertilizer ex- 

 periment in orchard management, is designed primaril}^ for experi- 

 mental work. 



The veterinarian continued experiments on the comparative value 

 of different forage crops for hogs in different sections of the State, 

 studied prevalent cattle diseases, together with the control of stomach 

 worms in sheep, tested the use of the silo in wintering cattle, and 

 made observations in breeding experiments with poultry on color 

 transmission as related to Mendel's law. The dairyman worked 

 largely on city milk control in cooperation with city authorities. He 

 scored dairies and took samples for bacteriological anal3'sis from 54. 

 Some of the data secured were prepared for publication. A feeding 

 experiment was made comparing broom sedge and pea-vine hay with 

 mixed hay. 



The chemist continued the study of the sugar content of French 

 cider apples, and studied the composition of short clippings of blue- 

 grass pastures. 



In agronomy, acclimatization work with corn w^as pursued and ex- 

 periments were made with two strains of corn to determine the possi- 

 ble influence of mixing on the jneld. Work on the improvement of 

 wheat, cowpeas, soy beans, and other field crops by selection was 

 carried on and the permanent rotation and fertilizer plats were con- 

 tinued. 



The plant pathologist studied tomato rot and tomato spot, to- 

 gether with the cause of frog-eye spot on leaves of spinach. About 

 25 hybrid varieties of tomatoes were tested for disease resistance. 

 The results of a study of club root of cabbage were published in 

 Bulletin 191 of the station. The results of experiments showed that
