thin husks, derived from Chevalier, Hanna, or other European types, and grown 

 principally in Montana, Idaho, Colorado, and California. 



The statement is made that only 6-rovved barleys of the Manshury related 

 varieties can be considered as first class for the preparation of chill-proof beers, 

 especially pasteurized bottle beers, and that the extipaet yield from fine grist 

 under laboratory conditions from malts made from such barleys often reaches 

 72 to 75 per cent of the dry matter. 



Owing to the great differences in American barleys the author believes that of 

 the different factors in the valuation of European barleys only the following 

 are adaptable to the American crop: Siftiugs on shaking screens of a certain 

 .'-ize mesh, albumen content, and thickness or quantity of husk. 



The influence of distance between plants on the quantity and quality of 

 fodder beets, G. Fkolich (Illiis. Lamlw. Ztci.. 21 (1907-), No. 30, pp. 213, 21Jt).— 

 Experiments were conducted in which fodder beets were grown at different 

 distances. The yields secured, together with the composition of the product, 

 were determined. The variety grown in these tests was the Friedrichswerth 

 fodder beet, and the results were most satisfactory from rows 14 in. apart, with 

 the plants 9 in. apart in the row. 



The relation of leaf production to yield of sugar was studied, and it was 

 found that a leaf production o'f 100 gm., in the case of the Friedrichswerth 

 beet, at harvest time corresponds to a sugar production of 44 gm. 



Corn-breeding work at the experiment stations, J. I. Schulte ([/. »S'. Dept. 

 Agr. Yearbook 1906, pp. 219-294). — A summary of the more important corn- 

 breeding work carried on by the experiment stations in this country. 



Cotton production, 1906 {Bur. of the Census [U. »S'.] Bui. 16, pp. 6S, maps 

 12). — This bulletin is a report on the production of cotton in 1906, with com- 

 parative statistics from 1902 to 1905, and data regarding cotton growing in 

 foreign countries. Including linters and counting round as half bales, the crop 

 of 1906 amounted to 13,305,265 bales, as compared with 10,725,002 for 1905 and 

 13,697,310 for 1904. 



In 1906 the Sea Island crop consisted of 57,5.50 bales, being the smallest i)ro- 

 duced since 1892 when 45,418 bales were secured. The cultivation of Sea Island 

 cotton in this country, according to ginners' returns, is confined at present to 

 selected poi-tions of 14 counties in Florida, 24 in Georgia, and 4 in South 

 Carolina. 



The statistics presented in tabular form include data with reference to pro- 

 duction by States and counties, the number of ginneries operated in 1906, and 

 the production, consumption, exports and imports of the United States from 

 1790 to 1906, and the quantity and value of exports of cotton seed and its 

 I)roducts from 1870 to 1906, inclusive. It is shown that about one-fourth of our 

 production of cotton-seed oil is exported, mainly to the Netherlands, France. Ger- 

 many, and Austria, and that nearly one-third of the cake and meal annually 

 niamifactured in this country is exported, principally to Denmark and Germany. 



The history of the cowpea and its introduction into America, W. F. Wight 

 (f/. .S'. Dept. Agr., Bur. Plant Indus. Bui. 102, pp. Jf3-59, pis. 3).— This bulletin 

 is a brief history of the introduction of the cowpea (Vigna nngulculata) into 

 -America, i)resented with the purpose to establish as nearly as possible the time 

 of its introduction and to ascertain the region to which it is native. No evidence 

 was found that T. umniieulata was one of the native beans of America, but 

 it appears to have been first introduced into Jamaica at some time between 

 1672 and 1687 and to have reached the southern United States later than this 

 but before 1737. Its use apparently extended gradually northward until it 

 reached the Potomac about 1790 or 1795.
