328 EXPERIMENT STATION RECORD. 



between tliis mutant and other forms is said lo have j^iven some interesting 

 results. 



Experiments with Primula sinensis, II. 1*. Gregory (Jour. Genetics, 1 



(1911), No. 2, pp. 73-132, i)ls. 3, figs. 2). — A study has been made of P. sinensis, 

 particular attention being paid to lieterostylisra, leaf shape, habit, double 

 flowers, characters of the eye of the flower, and color. The principal object of 

 the investigation was to determine the inheritance of heterostylism and of color. 

 At the same time records were kept of certain other characters, the inheritance 

 of these for the most part l^eing of a simple type. 



A census catalog'ue of Irish fungi, J. Adams and G. H. Pethybridoe 



(Proc. Roy. Irish Acad., 28 {1910), No. Jf, Sect. B, pp. 120-166, map i).— This 

 catalogue includes a compilation of previous lists and of species from other 

 publications on Irish fungi up to 1910. The distribution by counties of each 

 species, an extended bibliography of Irish fungi, a list of synonyms, and an 

 Index to the genera are also given. 



FIELD CROPS. 



On the correction of results obtained in field trials, R. K. Kristensen 

 (Tidsskr. Landhr. Planteavl, 11 {1910), No. 4, pp. 627-639).— A discussion of 

 the value of the method of Holtsmark and Larsen for correcting errors in field 

 trials due to lack of uniformity in the soil (E. S. R., 18, p. 436). 



The results of electroculture in Hedewigenkoog, Clausen {Landiv. Wchnhl. 

 Sehles. Hoist., 61 {1911), No. 5, pp. 83-86).— The results of electrocultural ex- 

 periments W'ith clover, wheat, and oats are reported. The data obtained do 

 not indicate that the action of the electrical installation had anyeffect upon the 

 growth of the crops. 



Experiments with shelter for agricultural crops, 1910, O. Kristensen 

 (Ber. Rihe Amis Landbofor. Have'br. og Husmands, IDIO, pp. 20, figs. 13). — 

 These experiments, like those of the preceding year, were conducted by Ribe 

 county agricultural societies (Jutland). Six series of experiments were car- 

 ried through with shelters of different heights and position, the crops experi- 

 mented with being rye, oats, barley, rutabagas, clover, and grass. 



The experiments with spring grains gave rather indefinite results, but greatly 

 increased yields were obtained in the case of the other crops. The growth of 

 the grasses and clovers was especially benefited by shelter. The increase in 

 yields of hay obtained from the protected plats ranged from 12 to 50 per cent 

 in the different trials. 



Fertilizer experiments with garden crops and fruit trees are also reix)rted. 



The choice of crops for alkali land, T. H. Kearney ( U. 8. Dept. Agr., 

 Farmers' Bui. 4-^f6, pp. 32). — This deals with the nature and appearance of 

 alkali, its eft"ect upon plant growth, and the selection of crops adapted to alkali 

 land and to different grades of alkali. The alkali resistance of different crop 

 plants is also discussed. 



Remarks on dry farming, N. M. Ttjlaikov {VQstnilc Russ. SelsJc. Khoz, 

 1909, No. li2-4Jf; ahs. in Zhur. Opytn. Agron. {Russ. Jour. Expt. Landiv.), 11 

 {1910), No. -i, p. 596). — The author compares the results of American and Rus- 

 sian dry-farming investigations. 



[Work with field crops at the Hawaii Station], E. V. Wilcox, W. P. Kel- 

 ley, and F. G. Krauss {Hawaii Sta. Rpt. 1910, pp. 12-lJf, 43, 44, 51-64, pis. 6).— 

 In plat and ix)t experiments it was observed that "nitrate of soda api>eared to 

 produce no beneficial eft'ect, while ammonium sulphate was very active in pro- 

 moting growth and yield of grain." Further experiments are being conducted.
