732 EXPERIMENT STATION RECORD. [Vol.41 



1-17-72, which stood up better than commercial Sixty Day and also excelled it 

 in yield, seems to be of much promise as compared with Iowa 103. On the 

 basis of the three-year yield test, pare lines of several varieties gave evidence 

 of promise. From the breeder's standpoint it seems that the isolation of a 

 higher yielding strain is more important thau the variety. Selections of the 

 following varieties are deemed worthy of further test: Minota (a Minnesota 

 selection), Garton 473, Garton 784. Scottish Chief, Irish Victor, Silvermine, 

 Lincoln, and Kherson. It is stated that ail the plant breeder can, hope to accom- 

 plish in three or four years is to determine the sorts which deserve further test, 

 the linal trial being for the purpose of determining the adaptability of the sorts 

 to special conditions and localities. The pairing method for the determination 

 of the probable error gave about the same result for the 1918 oat test as the 

 use of check plats systematically distributed and grown every tliird to fifth plat. 



Part II. Investigations in barley hreeding. by H. V. Harlan and H. K. Hayes 

 (pp. 45-56). This describes work conducted in cooperation with the Office of 

 Cereal Investigations, the results of which may be summarized as follows : 



Some head selections of Manchuria barleys proved to be low yielders each 

 year, while others gave high yields each year. Nearly as wide variations in 

 yield were found when comparing head selections v.'ithin a variety as were ob- 

 tained by comparing different varieties. Several smooth-awned sorts were 

 compared with standard Minnesota types, the results indicating that smooth- 

 awned bai'leys of high yielding ability can be obtained. A cross between Man- 

 churia and a low-yielding stiff-strawed sort, kno\A'a as South African, has given 

 two selections having yielding ability and stiffer straw than the Manchuria 

 parent. Results reported are said to show the necessity of testing a new pro- 

 duction in various localities of the State before recommending its general intro- 

 duction. 



Leg'uminous crops on the prairies [of Canada], T. J. Harrison and J. Mc- 

 Caig {Ayr. Gaz. Canada, 6 (1919), No. 6, pp. 552-557, figs. 5). — Brief notes are 

 presented on the adaptation and production of alfalfa and red, alsike, white 

 Dutch, and sweet clovers in Manitoba, and alfalfa and red, alsike, and sweet 

 clovers in Alberta. 



Paper-making' materials of the Philippines, J. F. Boomer {U. S. Dept. Com., 

 Com. Rpts., No. 178 (1919), pp. 632-6Ji9).— Based on data gathered by G. F. 

 Richmond, information is presented relative to fiber and other raw materials 

 suitable for the manufacture of paper pulp and of raw materials required for 

 the production of chemicals employed in paper-pulp making found in the Philip- 

 pine Islands. The paper-making materials mentioned include bamboo, abaca 

 waste, cogon (Impcrata ejcaltatn), talthib {Saccharum spontaneum), plantains 

 {Musa. paradisiaca) , bananas, maguey {Agave cantula), and miscellaneous 

 minor sources of paper stock. Raw materials for the manufacture of paper- 

 making chemicals include lime, clays, and sulphur. 



Silage crops other than corn [in Canada], J. M. Trueman, R. Summerby, H. 

 Barton, Brother Athanase, W. Toole, .1. H. Ellis, .1. Bracken, J. McCaig, 

 and P. A. Boving (Agr. Gaz. Canada, 6 (1919), No. 6, pp. 538-544)- — Information 

 is presented on the utilization of various crops other than corn for silage in dif- 

 ferent parts of Canada, including notes on alfalfa, rye, clover, soy beans, Sudan 

 grass, millet, rape, buckwheat, sunflowers, and mixtures of cereals, peas and 

 vetch. 



Alfalfa seed growing and the weather, in Utah, J. C. Alter {U. S. Mo. 

 Weather Rev., 47 (1919), No. 5, pp. 330-332, figs. -?).— The relation of tem- 

 perature and rainfall to alfalfa seed production in Utah is discussed. 



It is stated that the crop requires sufficient moisture during its early growth 

 to produce vigorous plants followed by rather dry weather during the blooming
