 — Owing to the fact that there are no reliable seed growers in Cyprus and that imported seeds 

 are not satisfactory due to not being acclimated, farmers and gardeners are advised to raise 

 their own seed of such crops as beans, Indian corn, lettuces, melons, peas, cucumbers, 

 spinach, and tomato. Recommendations are given for producing high grade seed. — W. Stuart.

417. CocKERELL, T. D. A. The Girasole or Jerusalem artichoke. Monthly Bull. State 

 Commission Hort. California 8:243-250. 1919. — The Girasole, Helianthus tuberosus, is a 

 native of America, is tall, erect, and has an abundance of foliage and underground tubers. 

 The latter mature in the fall, remain in the soil during winter unaffected by frost, and are 

 good for domestic use and as animal feed. The tubers do not contain starch but instead inulin, 

 which for assimilation requires hydrolysis. Artificial hydrolysis may prove practicable and 

 desirable. — E. L. Overholser.
