The Tlieory of Antagonism of Salts and Its Significance in Soil Studies was 

 presented by C. B. Lipman, who reported studies of the effect of certain combi- 

 nations of alkali salts in barley cultures and upon soil organisms. Antago- 

 nisms were quite pronounced, which suggested the possibility of chemical means 

 for alkali reclamation. 



In a paper on The Relation of Ecology to Agriculture, L. H. Pammel pre- 

 sented an argument for the importance of such studies in connection with other 

 lines of agricultural work. 



Variation in the Tongue Color of Jersey Cattle was traced by Raymond 

 Pearl, in a herdbook study of registrations made in 1893 and in 1913, twenty 

 years apart. The results indicated " a simple case of Mendelian inheritance, in 

 which pigmented tongue is the dominant character and nonpigmented the 

 recessive." 



F. W. Rane described What Massachusetts Has Accomplished for Science 

 in Her Fight Against the Gipsy and Brown-tail Moths. This related to the 

 importing and breeding of parasites and other natural enemies, the development

American Association for the Advancement of Agricultural Teaching. — This 

 association held its fourth annual meeting in Washington, November 11, 1913. 



The opening topic was Home Project Work v. Laboratory and School Garden 

 Plat Work for High School Students. C. G. Selvig of Crookston, Minn., held 

 that the purpose of agricultural high schools is to train future farmers and to 

 help farmers to become more efficient. The use of school land should, there- 

 fore, be to supply plats to landless pupils and to perform demonstrations for 

 the benefit of the school and the community. An inquiry conducted by him in- 

 dicated that the possibilities regarding the use of land at school and at home 

 are barely beginning to be realized. W. R. Hart of the Massachusetts Agri- 

 cultural College assigned a different function to the agricultural high school,

 pedagogics and practice teaching to the regular agricultural course. In his 

 opinion, " in institutions where thorough preparation of teachers of agriculture
