FIELD CROPS. 681 



Besults of variety tests of cotton in Mecklenburg County, C. B. Williams 

 (North Carolina Sta. Circ. 16 {1914), PP- -J)- — This circular describes tests on 

 two types of soil. 



The results are reported as emphasizing the importance of using the best 

 of the early maturing varieties on a rather stiff clay soil of the Piedmont por- 

 tion of the State, especially if the section is near the limit of the growth of 

 cotton. For the Cecil sandy loam with a red clay subsoil, the best of the later 

 varieties will, in many eases, produce the greatest net return per acre. 



Testing cotton seed for germination, W. C. Lassetteb {Arkansas Sta. Circ. 

 22 {1914) < PP- 2). — A practical method for testing cotton seed and com is 

 described. 



Spinning tests of upland long-staple cottons, F. Tatlob and W. A. Sheb- 

 MAN {U. S. Dept. Agr. Bui. 121 {1914), pp. 20).— This bulletin discusses soil 

 types represented, variations in grades and staple, lengths, invisible loss, card 

 waste, relation of grade to waste, comparisons at the comber, comber tests, 

 value of waste differences, accuracy of machine work, factors influencing waste, 

 tests of breaking strength, and cultural characteristics, compares early and late 

 picked cotton, and gives data on tests made at the New Bedford Textile School. 



" These tests show that careful breeders in the Carolinas are producing cotton 

 fully equal in almost every respect to average Deltas of the same length. They 

 also show that several strains now grown in commercial quantities in the 

 Southeast are less wasty than average Deltas, although not so strong. These 

 varieties are earlier, have larger bolls, and are usually more prolific than Delta 

 types. These uniform varieties are the result of intelligent breeding work. 

 The importance to the spinner of such work can hardly be overestimated. It 

 suggests the wisdom of more direct dealing between spinners and careful pro- 

 ducers, that the latter may be guarantied suitable premiums for their superior 

 products." 



A new cover crop, W. G. Cbaib {Roy. Bot. Gard. Keiv. Bui. Misc. Inform., 

 No. 2 {1914), PP- 76, 77). — A description of a leguminous plant {Dolichos hosei) 

 indigenous to Sarawak and grown experimentally at Kuala Lumpur. It is 

 noted as proving a successful cover crop and as growing from cuttings. 



Notes on a creeping bean, E. Hose {Agr. Bui. Fed. Malay States, 1 {1913), 

 No. 7, p. 276) . — The plant noted above is described and its successful cultivation 

 as a cover crop reported. 



Mireken nuts [candle nut] (Aleurites moluccana) (Agron. Colon., 1 {1914), 

 No. 10, p. 120). — The analyses here given show the fat to range from 62.48 to 

 67.12 per cent and the protein from 19.4 to 25.3 per cent. 



Oats, M. Nelson and C. V. Ruzek {Arkansas Sta. Bui. 118 {1914), pp. 625- 

 637, fig. 1). — In this bulletin are given the methods and results of several 

 years' cultural variety tests. 



For winter oats variety-test-yields reached up to 54.5 bu. per acre during 1909- 

 1913 and spring oats up to 65 bu. It was found that the winter varieties pro- 

 duce taller straw, larger yields per acre, and heavier grain per bushel than do 

 the spring varieties, but the spring varieties mature earlier and stand up better. 

 Virginia Turf, Winter Gray, Winter Turf, and Snoma are the best winter varie- 

 ties included in these tests, and Burt, Hybrid No. 45, Red Rust Proof, and 

 Daubenny the best spring varieties. The northern varieties of oats have not 

 given good results in comparison with the other varieties. 



For the northern part of the State the results indicate that the first half of 

 March is the best time for seeding spring oats, while for the central and south- 

 ern part of the State the last half of February is preferable. For the northern 

 part of the State the latter half of September gives best results of seeding 

 winter oats, but for the central and southern parts of the State the first two
