factors were not quite parallel. The authors believe that a determiuation of 

 the extract content is more reliable as a means of judging the malting quality 

 of barley than the protein determiuation. An increase in protein was further 

 associated with a high percentage of hull. It was also found that the malt 

 extract produced from the dry matter of the grain decreased as the protein 

 content increased. This fact was observed in practice as well as in laboratory 

 experiments. In the process of malting the loss of protein was greater in 

 high protein than in low protein barley. 



A test of the producing power of some Texas seed corn, U. L. Bennett 

 (Texas Sta. Bid. 92, pp. 8). — The purpose of the experiment was to determine 

 the variation in productiveness of corn grown by different persons, and of ears 

 grown by the same person. Ears from a large number of farmers were tested, 

 using an ear to a row 500 feet long. A low rainfall during winter and spring 

 reduced the yield from all the ears. The highest yielding ear pi-oduced 26i 

 bu. per acre, or 12 bu. more than the average yield for all the ears. 



Notes on the growing and selecting of seed corn and selecting and storing 

 seed ears are given.

 Assoc. Proc., 2 {1906), pp. S9-93). — This article describes fully each successive 

 step of the corn breeding methods employed by leading corn breeders of 

 Illinois. 



Value of corn pollen from suckers v. from main stalks, C. P. Hartley 

 (Amer. Breeders' Assoc. Proc, 2 (1906), pp. lJfl-14-i)- — The results of the 

 experiment reported in this paper indicate that the various ears produced by 

 a stalk are of equal value for seed, that the pollen from the tassel of a sucker 

 is of equal value with the pollen of the stalk that produces the sucker, and that 

 the tendency to form suckers is hereditary and can be controlled by breeding.

Cotton in Algeria, F. Godard (BuL Off. Goiivt. Gen. Algerie, 1007, >^iip- 7. 

 pp. 63-85). — Cultural experiments carried on in the region of Philipi)eville 

 in 190G have shown that cotton can be profitably produced on nonirrigated 

 lands in certain parts of Algeria. The 2 Egyptian varieties. Mit-Afifi and Yano- 

 vitch, particularly the first, appear well adapted to the coastal plains of the 

 country and also to certain soils in the region of Pliilipi>eville. Georgia long 

 staple iiroved the least resistant to drought, and its culture is therefore recom- 

 mended oidy on the rich plains near the sea. Mississippi proved to be early 

 and liardy and is believed to be better adapted to the higher altitudes than the 

 other varieties mentioned.
