Sugar beets in Sanpete and Sevier counties, L. Foster ( Utah Sla. Bui. 63, j)p- 

 22). — Results of cooperative experiments in these counties, with cultural suggestions 

 and a discussion of factory conditions. The average sugar content of the beets grown

Forcing tomatoes, A. T. Jordan {New Jersey Stcis. Bui. IJ).!., jyp. 

 18). — Tlic iiuthor describes the methods g'enerally observed in New Jer- 

 sey in growing tomatoes under glass, and presents the detailed results 

 of his investigations of problems connected with forcing tomatoes. 



Thickness of sett hig (pp. G-S). — Tomato plants were allowed li, 2, 2^, 

 3, and 3i sq. ft. of bench surface per plant. Four crops were grown. 

 In order to admit light and permit of a better circulation of air about 

 the plants, it was found necessary to clip the leaves of plants given 1\., 

 2, and 2^ sq. ft. of space. Watering with liquid manure was practiced. 

 The best results were obtained from the plants given the greatest num- 

 ber of applications. The maximum yield per plant was from the plants 

 having 2^ sq. ft. of surface, but the maximum 3neld per square foot of
