Sugrap-beet Varieties, Comparative Tests of. By J. E. W. 



Tracy and J. F. Eeed (U.S.A. Dep. Agr., Bur. PI. hid., Circ. 37, Sept. 

 1909). — The tabulated results of tests which have been conducted at 

 different stations in order to determine the ability of various strains 

 and varieties of sugar beet to produce a paying crop under varying local 

 conditions. The testing at each station was done under similar condi- 

 tions and in the same manner, and all plots were planted as a farm 

 crop, no care being taken to produce extra yield or. high sugar content 

 that could not be secured in a general crop. — M. L. H.

Tamarisks for Inland Planting-. By E. Curgwen [Garden, 

 Nov. 20, 1909, p. 564). — There are no grounds for the popular notion

 the ornamental character of the plant, with its feathery masses of 

 apricot-coloured flowers. Several hardy varieties are mentioned. 

 T. gallica, flowering from May to October, and the similar but finer 

 T. tetranda are specially commended. — H. R. D.
