548 EXPERIMENT STATION RECORD. 



conditions of culture in Tunis arc so different from those in France that the perform- 

 ance records of a variety in the two countries can not be compared. 



Corn growing- in Virginia, A. M. Soule ( Va. Ikpt. Ayr. and Immig., Farmers' 

 Bui. 4, pp. 31, figs. 20). — Corn growing in Virginia is discussed, the total yield of the 

 state compared with that of several other States, and the possibilities of improving 

 the industry pointed out, Directions are given for the selection of corn and the 

 growing of seed. The causes of poor yields and the influence of planting upon the 

 yield are considered. Notes are given on a number of record crops grown within 

 the State, and the cost of producing corn on an S-acre tract of land under Virginia 

 conditions is estimated. 



The production of good seed corn, ('. P. Hartley ( U. S. Dept. Agr., Farmers'' 

 Bui. 229, pp. 23, figs. 10). — This bulletin comments briefly on the general demand 

 for well-bred seed corn and the need and importance of improved strains for different 

 localities; describes more fully the important characters the stalk, ear, and kernel 

 should possess, and outlines completely a method of corn breeding including the 

 choice of a strain or variety, the selection of parent ears; the location, arrangement, 

 and management of the breeding plat, and the selection of seed. 



Directions for the care of seed corn and testing its germination are also given. 

 Notes by H. J. Webber on the selection and care of seed corn when taken from the 

 field instead of the breeding plat are appended. 



Pedigreed seed corn, C. G. Williams {Ohio Sta. Circ. 42, pp. 11, dgm. 1). — A 

 paper discussing the value of corn breeding, describing the arrangement of the breed- 

 ing plat with directions for its management, and outlining a system by which pedi- 

 greed and certified seed corn may be produced. 



Score card for dent corn ( Ohio Sta. Circ. 43, pp. 3). — A score card for dent corn 

 is given, with an explanation of the different points as they are applied in corn 

 judging. 



Cultivation of cotton on the Odessa Experiment Field, Rotmistrov (Zeml. 

 Ghaz., 1905, No. 9, pp. 364, 365). — Experiments were made with American upland 

 and Turkestan cotton. The American variety gave somewhat better results than the 

 Turkestan. — p. fireman. 



Fertilizer experiments with hops near Saaz, A. Mahner {Dent. Landw. Presse, 

 32 [190.5), Von. 52, pp. 45. '-454. figs. 5; 53, pp. 405, 406) .—The results of these exper- 

 iments showed that the use of barnyard manure alone had no influence upon the 

 development of the hop plant with reference to its structure, and that the commer- 

 cial fertilizers were not injurious to the quality of the hops, as is contended by many 

 producers. 



A study of the lupulin content pointed out the importance of using a complete 

 application of commercial fertilizers. Kainit when applied in the fall or winter was 

 preferable to 40 per cent potash salt, while for spring applications the potash salt is 

 recommended. Although barnyard manure was injurious to the proper development 

 of the strobile and reduced the lupulin content, the author is of opinion that its use 

 in hop culture is necessary for the maintenance of soil fertility, and that it is largely 

 a question of when to apply it. The importance of barnyard manure in connection 

 with hop culture is discussed, and a method of conducting fertilizer experiments in 

 hop yards is described. 



The peanut and its culture, YV. X. Roper I Petersburg, Va.: American Nut Jour- 

 nal, 1905, pp. 75, figs. 12). — A brief treatise on the peanut industry of this country, 

 giving directions for the culture of the crop and its preparation for market. 



The injurious effect of crude potash salts on the potato, H. Suchtixg 

 {Landw. Vers. Stat., 61 {1905), No. 5-6, pp. 397-449). — A series of pot experiments 

 to determine the effects on the potato of magnesium, sodium and chlorin contained 

 in crude potash salts is reported.
