for the frosted wheat and 1,509 for the unfrosted wheat. The grain weight per 

 row was 1,457 and 1,375 gra., respectively. 



Germination tests of samples of winter and spring wheat, oats, and barley 

 taken one week, one month, and two months after threshing indicate that ger- 

 mination improves greatly a few weeks after threshing. 



Twenty-one of the worst weeds encountered in Montana are briefly described 

 and illustrated. 



Results of seed inspection, 1915 and 1916, J. P. Helyab et al. {New Jersey 

 Stas. Bui. S02 (1916), pp. 3-23).— Continuing work previously noted (E. S. R., 

 34, p. 832), the author states that during the past two years more attention has 

 been paid to the analysis of vegetable seeds offered for sale in bulk on the New 

 Jersey markets. Analyses of oflicial samples for 1915 incUule red clover, nlfalfn, 

 crimson clover, cowpeas, Canadian field peas, beans, lima beans, sweet corn, 

 peas, radishes, tomatoes, turnips, cucumbers, and cubbages. 



The 1916 analysis was confined entirely to vegetable seeds, except for crimson 

 clover seed investigations. A comparison of the analyses of 29 crimson clover 

 samples showed a variation in germination percentage of from 24.5 to 92.5 

 per cent. 



Weeds in the Government of Novgorod, A. Maxzew {Trudy Biuro Prlld. 

 Dot. {Bui. Appl. Bot.), 9 {1916), No. 4, pp. 137-174).— The weeds found in 

 winter rye, spring oats, barley, flax, potatoes, and cabbage in the Government 

 of Novgorod are discussed, those peculiar to each crop listed separately, and all 

 the weeds identified (81 in number) listed alphabetically and briefly described. 

 It is pointed out that only about 12 of these weeds are serious pests and that 

 as a rule the annuals are more noxious than the perennials. 



Broom rape {Jour. Bd. Agr. [Londan], 23 {1916), No. 5, pp. 478-481, fig. 1). — 

 This is a note on the parasitic weed broom rape {Orobanche minor), which was 

 unusually prevalent in English clover fields during the summer of 1916. The 

 life history of the plant is briefly outlined, together with preventive and control 

 measures. 



Bed sorrel and its control (Rumex acetosella), F. J. Pipai, {Indiana Sta. 

 Bui. 197 {1916), pp. 28, figs. 16). — Red sorrel Is described and measures for its 

 control outlined. 



An abundance of red sorrel in a field is held to indicate soil acidity, in- 

 suflicient organic matter or mineral plant food, or inadequate drainage. Pot 

 tests with several types of soils indicated that correction of such unfavorable 

 conditions will stimulate clover production and check the growth of the sorrel, 

 although lime was not found to have harmful effects on the growth of the 

 plant itself. 



Other tests indicated that eradication of the weed may be effected by one or 

 more applications in the form of a fine spray of a 20 per cent solution of sul- 

 phate of iron or of full strength orchard heating oil. For badly infested fields 

 cultivation or grazing with sheep is recommended, and it is pointed out that 

 pending eradication sorrel may be cut and utilized for feed.
