the lowest weight per bushel. These were still well above the legal weight of 

 32 lbs. It Is of interest to note that the Kherson shows a progressive increase 

 in its weight per bushel for the four years that it has been grown in this 

 State. . . . 



"Of the varieties which have been tested for four years the Irish Victor, 

 Imported Scotch, Lincoln, and Prosperity have made the best showing. With 

 the exception of the Imported Scotch there appears to be but little choice be- 

 tween these varieties. The Imported Scotch has shown much less variability 

 in respect to all its characters (with the exception of straw weight) than any 

 of the other varieties. This is true both of inter- and intraseasonal variation. 

 Under the conditions of seeding and growth at Highmoor this variety can 

 be expected to produce a little over 60 bu. per acre every year. The chief 

 objections to this variety are its relatively small weight per bushel and the 

 yellow color of its grain. This latter objection is not very serious although 

 yellow oats do not meet with so much favor on the market as the white* 

 varieties." 



In discussing the results of the experiments the means, standard deviations, 

 and coefficient of variation are used in estimating the values of the different 

 varieties as affected by inter- and intraseasonal environmental conditions. 



Peanuts (Arachis hypogea), C. D. Girola {Rev. Facult. Agron. y Vet. La 

 Plata, 2. sen, 10 (1914), No. 3, pp. 9-23, fig. i).— This article gives the history, 

 geographical distribution, cultural methods, cost of production, and chemical 

 analyses of the nuts and of the oil calje. 



Some ecological evidence of the original habitat of the Irish potato (So- 

 lanum tuberosum), C. L. Fitch {Proc. Soc. Hort. Sci., 10 (1913), pp. 99, 100).— 

 As evidence that the potato plant is a native of sandy open soils and a mari- 

 time atmosphere, or misty well-drained mountain slopes free from prolonged 

 and heavy rains, the author notes his observations of the open structure of 

 the stoma of the potato leaf, permitting rapid evaporation, and the loose inco- 

 herent structure of the root cap which is adaoted only to penetration in open 

 soils. 



Observations on a bastard type of the Pearl potato, C. L. Fitch (Proc. Soc. 

 Hort. Sci., 10 (1913), pp. 100-IOj^).— In this article the typical Pearl potatoes, 

 the " running out " type, and the bastard type are described and the results of 

 cultural tests noted. 



" The general summary of these results is that the normal Pearl tuber pro- 

 duces plants that are fairly productive and healthy, both in the district where 

 it is most grown and in Minnesota, Wisconsin, and New York ; that Pearl 

 plants grown from tubers of the common run out type are most subject to dis- 

 ease, produce a poorer crop, and are more apt to bloom ; while tubers of the 

 bastard type produce plants that are vei-y weak and lacking in resistance, 

 that bear a much smaller crop, and that bloom profusely and produce abundant 

 virile pollen and large fruits with many seeds. 



" These facts are evidence that degeneracy of the potato tuber in the case 

 of the Pearl in Colorado is accompanied in like degree by weakness and lack 

 of resistance to disease." 



Results of change of seed potatoes on moorlands (Ztschr. Moorkultur u. 

 Torfverwert., 12 (1914), No. 3, pp. 107, 108). — ^The data show increased yields 

 of potatoes from seed obtained from similar soil elsewhere over home grown 

 seed of the same variety. Seed from sandy soil proved inferior to home 

 grown seed.
