 figs. 3). — At the tenth annual session of the International Dry-farming Con- 

 gress the following papers relating to field crops were presented : High Altitude 

 Crops, by T. S. Parsons ; Grasses in Relation to Dry Farming, by C. V. Piper ; 

 Dry Farming in Western Canada, by J. Bracken ; Cultivation to Conserve Soil 

 Moisture, by W. W. Burr; Effect of Soil Alkali on Dry-farm Crops, by F. S.

Notes on dry farming in the following countries were given by their respec- 

 tive representatives : Colombia, Nicaragua, Australia, South Africa, China, 

 Greece, Russia, Belgium, Sweden, Roumania, Guatemala, Iceland, and Ar- 

 gentina. 



Dry fanning in Colorado, A. Kezeb (Colorado Sta. Bui. 22^ (1911), pp. S-40, 

 figs. 12). — General principles of dry-land farming applicable to Colorado con- 

 ditions are discussed in detail, and crops deemed suitable for dry farming 

 recommended and their production described. 



Grasses under drought conditions at Hawkesbiiry Agricultural College, 

 W. D. Keble (Agr. Gaz. N. S. Wales, 27 (1916), Xo. 10, pp. 694-697, figs. 3).— 

 Brief notes are given on the behavior of certain grasses under extreme drought 

 conditions during the year 1915 and part of 1916. The precipitation for the 

 year ending December 31. 1915, was 16.725 in., the lowest in 51 years ; and 

 for the year ending May 31, 1916. only 13.195 in. The grasses noted are 

 Eragrostis curviila, Chloris gayana, Andropogon intermedius, E. leptostachya, 

 Paspalum dilatatum, Anthistiria avenacea, Pollinia fulva, and Andropogon sor- 

 ghum. 



Artificial reseeding of range lands, A. W. Sampson (Nat. Wool Groxcer, 6 

 (1916), No. 11, pp. 23-25, figs. 5). — This is a discussion of the results obtained 

 in various tests undertaken by the U. S. Forest Service in reseeding range 

 lands in restricted localities extending from Canada to Mexico. 



Fall sowing is recommended and the trampling of the seed by sheep was 

 found to be sufficient to work it into the soil. Successful seedings were 

 obtained with timothy, .smooth brome grass, perennial rye grass, Italian rye 

 grass, redtop, and Kentucky blue grass, in the order named. Of the clovers, 

 white clover gave the best returns. The moisture conditions of the land will 

 determine to a large extent the plants to be seeded, and with that in view the 

 following recommendations are made : Mixture for wet lands, redtop 5 lbs., 

 timothy 3 lbs., Italian rye grass 3 lbs., and alsike clover 2 lbs. per acre ; mixture 

 for moist lands, timothy 3 lbs., orchard grass 5 lbs., Kentucky blue grass 5 lbs., 

 and white clover 2 lbs. ; and mixture for medium moist lands, smooth brome 

 grass 6 lbs., timothy 4 lbs., slender wheat grass 5 lbs. Attempts at seeding 

 the drier lands Ijav^ Qot been successful.
