The corn crop of Delaware, A. T. Neale (Delaicarc Sta. Rpt. 1903, pp. 

 7-3-i). — This article presents some statistical studies based on census reports, 

 discusses the significance of rain in corn culture, describes the beneficial effects 

 which crimson clover may exert upon the corn crop, and gives practical details 

 in the utilization of corn fodder. 



It is believed that crimson clover on the land each winter, followed by corn 

 each summer, improves the corn-producing qualities of the lighter lands in Kent 

 and Sussex counties of the State, and that this is probably due to an increase 

 in the water-holding power of the humus derived from the clover crop. 



Hops in pi'incipal countries: Their supply, foreign trade, and consump- 

 tion, with statistics of beer brewing, E. Merritt (V. S. Dept. Agr., Bur. 

 Stat is. Bill. 50, pp. 34, dgm. 1). — This bulletin gives the production of bops in 

 the United States from 1850-1900, and the annual production and commercial 

 movement of this product from 1889-1905, together with the localization of the 

 production in this and the European countries. Figures are also given with 

 reference to the trade and consumption of hops in the United States and abroad. 

 The countries producing a surplus, and those partially or wholly dependent upon 

 foreign hops are enumerated, and the fluctuation in the price of hops is pointed 

 out and discussed. 



The data show that the United Kingdom, Germany, and the United States 

 consume the most hops, and that Austria-Hungary, Germany, and the United 

 States are the principal exporting countries. Germany imports from Austria- 

 Hungary and the United States, while France. Belgium, and the Netherlands 

 import from Germany. The United Kingdom supplies its demands from the 

 United States, the Netherlands, Belgium, and Germany. Of the 4 principal 

 hop-producing countries the largest yields per acre are obtained in the United 

 Kingdom and the United States, and the best quality of product is secured in 

 Austria-Hungary and Germany. 



The United Kingdom and France require a much larger quantity of hops to 

 the barrel of beer than Germany or other continental countries. The average 

 for the United States is below that of the United Kingdom, Australia, and 

 France, and above that of all other countries represented. The hops from coun- 

 tries Avhere special attention is given to quality bring better prices and are held 

 in higher esteem than American hops, even in our own country. The compar- 

 ative trade, production, and consumption of hops in the principal countries for 

 1900-1904, and the yields, exports, and imports of the different countries for 

 1901-1905, together with the quantities of beer brewed in the different countries 

 for 1890-1904, are given in tables. 



Germany, the United States, and the United Kingdom are the 3 principal 

 beer-producing countries of the world. Of the world's total beer production, 

 Germany is represented by 27.8 per cent, the United States by 23 per cent, the 

 United Kingdom by 22.6 per cent, Austria-Hungary by 8.5 per cent, Belgium by 

 (1.1 per cent, and France by 5.7 per cent. 



Duty of water on field peas, 1906, H. T. Nowell (^]'l/0)lli^lff Sta. Bui. 12, 

 pp. 16, figs. 13, dgm. 1). — Field peas under the flood method of irrigation showed 

 a wide variation in yield of dry forage and threshed peas, according to the 

 quantity of water applied. On G plats the highest yield of dry forage, 4.2 tons 

 per acre, was obtained with nearly 23 in. of water applied in 7 irrigations. 

 The highest yield of peas, 34.75 bu. per acre, Avas secured when about 20 in. 

 of water was applied in 4 irrigations. The yield decreased with either more 

 or less water. The relation of cost of irrigation to the value of increased 

 yield shows that a duty of water a little under 20 in. will probably give the
