 was produced by English, wliidi wei^lied .".S llis. per Imsliel. In considering,' the 

 average yields for 4 years it is shown that the late-maturing varieties were the 

 most prolific. 



The percentage of hull and the chemical composition of the whole oat. the 

 luill, and the meat were deterunned, and the results secured apparently indi- 

 cate that seasons favorable for a variety of oats decrease the percentage of hull, 

 that some varieties give uniformly a higher iiercentage of meat, and that 

 correlation seems to exist between the weight ]>er bushel and the percentage 

 of meat to hulls. As the rudimentary kernels decrease in size the percentage 

 of hull up to a certain degree increases. It was also found that the variety 

 weighing most per bushel is not necessarily the most valuable, and that the 

 thickness of the hull seems to be somewhat hereditary. 



In 1906 the yield of barley, owing to excess of rain, was very low. Among 

 the varieties grown for -t years Russian stands first, with an average yield of 

 41.7 bu. per acre, followed by common and Mansury, with 37.9 and 37.8 bu.. 

 respectively. Great Beardless gave the lowest average yield and AIcEwan Hul- 

 less the next lowest. The G-rowed varieties led in yield in nearly every case. 

 The 2-rowed varieties have weaker straw and are more easily affected by adA'erse 

 conditions than the (j-rowed sorts. 



The highest average yield of flax for 3 years, 14.4 bu. per acre, was secure«l 

 from Select Russian. A mixture of durum wheat and oats produced 1,95U lbs. 

 of grain per acre, while the grain grown separately produced only 42 lbs. more. 

 The mixed crop produced the larger proportion of wheat. The crops grown 

 sei)arately produced 3.8 lbs. more digestible protein and 7.7 per cent more digesti- 

 ble ether-extract than the mixture, while the mixture contained 20.1 lbs. more 

 digestible carbohydrates tlian the separate crops. 



Dry farming in New Mexico, .1. J. Yernon {Xew Mexico »S7«. Bid. 61, pp. 5.'f. 

 pin. SO). — Tills bulletin defines dry farming, describes in detail the different 

 practices it includes, gives reasons why fall seeding is preferable to spring seed- 

 ing, discusses the importance and methods of storing and conserving the moist- 

 ure, gives directions for the use of seed under dry farming conditions, and 

 points out the results that may be expected. 



The methods followed, as well as the results secured, in growing oats, sor- 

 ghum, melons, squash, corn, wlieat, alfalfa, spelt, potatoes, millet, barley, and 

 beans by dry farming at Isador and in the vicinity of Las Vegas are jiresented. 



Report of chemist [Field crops], A. L. Knisely {Oregon /S7fl. Rpt. 190o, pp. 

 ■')3--j7). — Experiments in steaming silage during the process of filling the silo 

 seemed to indicate that corn fodder is the crop best adapted to steaming. De- 

 terminations of acidity showed that untreated silage varied in acidity from l.ttl 

 to 1.94 per cent and averaged 1.58 per cent, while in the case of steamed silage 

 the variation M-as from 0..30 to 0.88, with an average of 0.53 per cent. 



Experiments to determine the effect of summer fallow were carried on in pot 

 culture tests. The data rejiorted show that in the fall of 1901, during the first 

 month in which leaching occurred, the summer-fallow pots lost from 3 to 5 

 times as much nitrogen as those not summer-fallowed, and during succeeding 

 years the summer-fallowed pots invariably lost considerably more nitrogen than 

 those upon which crops were grown. 



[Report of the] department of chemisti-y, F. \V. Morse (Neio Uampahire 

 Sta. Bui. 12U. pp. 239-2^2). — Several analyses of silage crops and of oat samples 

 representing the different weights ])er bushel of market oats are reported with 

 brief conunents. 



The results with oats show that the light oats are inferior to the heavy grades, 

 in ]»rotein. fat. and nitrogen.-free extract, while the fiber is higher. It is state<l
