 Jour. India 14: 639-644. 1919. — An address at the Coffee Planters' Conference at Mysore, 

 India. July 1918. It is urged that the growers select high-yielding coffee trees for propagation 

 in the belief that the present practice of raising nursery stock from "plantation run" seed is 

 resulting in the deterioration of the varieties. It is suggested that facilities be provided to 

 economic botanists for developing new varieties by hybridization. Author also reports that 

 a Mr. Jackson has obtained a vigorous and disease-resistant hybrid which comes true from 

 seed. [See Bot. Absts. 4, Entry 893.] — J. H. Kemplon.
