being 350 lbs. per acre. Wide spacing between rows, namely, 42 in., produced 

 larger yields of seed than 6-in. spacing. 



A table reports analyses of Sudan grass and other forage crops generally 

 grown In Oklahoma. The uses and value of the Sudan grass crop for soiling 

 and silage, pasture, catch croj), rotation crop, and forage are briefly noted. 



The commercial production of sug-ar-beet seed in Utah, F. S. Harris ( Utah 

 Hta. Bui. 136 {1!>15}, pp. //7-.58, fiy-H. (!). — In describing the meth(Kls for the 

 production of sugar-beet seed in Utah the topics covered include getting the 

 " mother seed," siloing, planting, caring for the crop, harvesting and threshing, 

 cleaning, yield, and cost. Data from crops grown in 1912, 191.3, and 1914 show 

 that beets from home-grown seed were higher in sugar content than the beets 

 from imported seed, although the yield from the imported seed was somewhat 

 higher. The average weight of see<l producetl by mother beets for the years 

 1905 to 1913, inclusive, ranged from 263.7 to 722.6 gm. per beet. 



In testing different methods of preserving mother beets during the winter in 

 the rows where they grew it was foinid that covering with manure 6 in. deep 

 was much more satisfactory than covering with 8 in. of straw or with 8 in. of 

 straw and 4 in. of soil, or covering by running a plow along the row. In the 

 latter case none of the beets survived the winter, while from the manure- 

 covered row 197 beets lived and i)roduced 26 lbs. of seed. 



The average seed production at the station for 1912, 1913, and 1914 is given 

 as 1,190, 1,354, and 1,571 lbs. per acre, respectively, and the estimated cost of 

 production as .$95 per acre. 



Sweet potato growing in the cotton belt, H. C. Thompson ( [;'. 8. Dept. Agr., 

 Office Sec. Spec. [Circ], 1915, Mar. 9, pp. 8). — Brief notes on cultural methods 

 and uses are given. 



Types and varieties of Maryland tobacco, W. W. Garner and D. E. Brown 

 (Maryhuid Stu. liul. 188 (191',}. pp. J.i5-152, figs. 4).— This bulletin describes 

 the characteristics of Maryland types of tobacco, together with some commercial 

 qualities, including the varieties Maryland Broadleaf, Maryland Xarrowleaf. 

 Maryland-Connecticut Broadleaf, Maryland-Burley Broadleaf, and Maryland 

 Mammoth. Instructions for producing and saving the seed under bag and for 

 the selection of seed plants are given. 



Data show the results of variety tests and the proportion of leaf to stalk in 

 different varieties, conducted in cooperation between the station and this De- 

 partment. " The results of these tests indicate that the Maryland-Connecticut 

 and the Maryland-Burley are desirable types for growing on tlie lighter soils, 

 which produce tobacco of fine quality, while the Mammoth gives promise of 

 proving at least equal to the best varieties on these light soils and decidedly 

 superior to all otlier varieties on the heavier, more fertile tobacco soils on which 

 other varieties produce tobacco of comparatively poor quality." The Maryland- 

 Burley Broadleaf and Maryland Mammoth jiroduced a considerably lower pro- 

 portion of stalk than the other three varieties. 



The quality of grass and rape seed found in Maryland markets in 1913, 

 C. P. Smith (Maryland Sta. Bui. 189 {1915), pp. i5-3-i 80). —This bulletin com- 

 pletes the published results (E. S. R.. 31. p. 438) of 1913 inspection work 

 amongst the Maryland field seed vendors and also presents the text of the 

 Maryland seed law of 1914. The seeds covered by the work in this bulletin 

 are timothy, blue grass, German millet, orchard grass, redtop, and Dwarf 

 Essex rape.
