111 IDOG liural New Yorker No. G i)roduced tlie smallest yield, an average of 

 28.91 bu. per acre, and Royal lied Clawsou the largest, an average of 38.38 bu. 

 per acre. The average yield of all varieties tested was 83.25 bn. per acre, the 

 average yield of the smooth varieties 33.08 bu., and of the bearded varieties 33.59 

 bn. per acre. The averag«> weight of all varieties was 60.75 lbs. per bushel, of 

 the smooth varieties (iO.43 lbs., and of the bearded 01.37 lbs. The average yield 

 of straw per acre for each variety was 3,024 lbs. 



In 1907 Dawson (xolden Chaff ranked first with 38.23 bu. per acre and ^lar- 

 tin Amber last with 20.20 bu. The average yield for all varieties was 31.35 bu. 

 The smooth varieties gave an average yield of 32.19 bu. per acre and the 

 bearded 29.68 bn. The average weight per bushel of all varieties was 62.65 lbs. 

 The smooth varieties weighed 62.29 lbs., and the bearded 63.37 lbs. to the 

 bushel. The average yield of straw for each variety this year was 4,.342 lbs, 

 per acre. 



Judging from long year averages, which are considered best for determining 

 variety qualities, Fulcaster, China. Koyal Ked Clawson, Reliable, and Dawson 

 Golden Chaff have given the best results under conditions existing on the sta- 

 tion farm. 



The effect of shade during ripening' on the proximate constituents of the 

 wheat kernel, R. W. Thatcher and H. R. Watkins {Jour. Amer. Chem. Soc, 

 29 {1901), No. 5, ;>/\ 76'.}-767). — Analyses of wheat from shaded and unshaded 

 plats showed that neither the moisture content nor the ash content was regu- 

 larly affected. In 5 out of 6 cases the protein content of the shaded grain was 

 higher. The starch content was decreased and the oil or ether extract slightly 

 increased by shading, though this increase was very small. 



'-From this it appears that significant effects upon the percentage of protein 

 and of starch in the kernels wei'e produced by shutting off the direct rays of 

 sunlight from the plants during the last 10 or 12 days of the ripening period. 

 A careful study of the figures fails to reveal any exact relation between the 

 decreased peix-eutage of starch and the increased proportion of nitrogenous 

 bodies. Hence it appears that the increase in the percentage of crude protein 

 is not due simply to the failure of the plant to build up its normal amount of 

 starch, but to some disturbance of the physiological processes caused by the 

 absence of direct sunlight." 



Dodder in relation to farm seeds, F. H. Hillman ( U. »S'. Dcpt. Agr., Farmers' 

 Bid. 306, pp. 21, figs. 10). — This bulletin discusses the importance of dodder as 

 an impurity in seeds, describes the character of dodder plants, the various kinds 

 of dodder and the kinds of seeds infested with it, ijoints out the relation of 

 dodder to the seed trade, and gives advice for buying seed and directions for 

 cleaning the same. 



Descriptions of the following dodder seeds are given: Flax dodder {Cuscuta 

 cpilimim), clover dodder {('. (i)itlnimiiin). small-seeded alfalfa dodder (C. 

 plaiiiflont), field dodder (('. amiisis). large-seeded alfalfa dodder (C inde- 

 cora), and Chilean dodder {('. rdccmosd chUrami).

Fruits and vegetables, E. H. Fkrius {Mississippi Sta. Bui. 101, pp. .',~ll, 

 fig. 1). — The work at the McNeill substation with fruits and vegetables was 

 continued along the lines of previous years (E. S. R., 18, p. 1127). Data are 

 given in this report relative to the use of various combinations of fertilizers 

 and marketing experiments with strawberries, asparagus, cabbage, Irish pota- 

 toes, and tomatoes,
