530 EXPEEIMENT STATION RECORD. 



Work at the several fields of the experiment stations for the Java sugar 

 industry, 1912, J. Schuit {Meded. Frocfstat. Java-Suikerindus., 4 (1914), No. 

 20, pp. 317-412; A7-ch. Snikerindus. Nederland. Indie, 22 {1914), No. 7, pp. 21S- 

 308). — Results are here given in tabular form and discussed regarding yields 

 and soil analyses of about 100 experimental fields. 



Experiments in thinning out sugar cane rows, A. H. Rosenfeld (Inter- 

 nat. Sugar Jour., 16 {1914), No. 185, pp. 220, 221).— Data, obtained from thinned 

 and unthinned plats of sugar cane show that there was nothing gained by 

 thinning sugar cane, for it is stated that a " considerable amount of cane is 

 lost, apart altogether from the expenses of the thinning operations themselves. 

 From the very slight difference in the average weight per stalk in the two lots, 

 it will be seen that in the first year at least the thinning out has not increased 

 the size of the stalks left growing. Fifty kg. more cane per row were obtained 

 from the lot not thinned out; that is, a difference in favor of this lot of more 

 than 3 tons per hectare. This difference is slight in itself, but it certainly 

 serves to indicate that it is not advantageous to thin out the rows." 



The shipment of seed cane specimens, J. A. Hall, Jr. {La. Planter, 50 

 {1913), No. 23, p. 366, fig. 1). — This article notes a method of shipping seed 

 cane in tin cans 18 in. long by 3 in. in diameter, in which the pieces of cane 

 are packed in loose, damijened charcoal. 



A rational system of payment for cane, L. G. Camp {La. Planter, 50 {1913), 

 No. 23, pp. 363, 364, fid- i)- — This article describes and discusses methods by 

 which the producer in Cuba and other parts of the West Indies is generally 

 paid for the sugar value of his cane on the basis of the average selling price 

 of sugar during the fortnight in which the cane was delivered. In Cuba the 

 average is about G per cent in sugar on the weight of cane. 



Tobacco growing in Ireland {Dcpt. Agr. and Tech. Instr. Ireland Jour., 14 

 {1914), No. 2, pp. 320-337; abs. in Jour. Bd. Agr. [London], 21 {1914), No. 1, 

 p. 58). — Results of experiments embracing 108 acres, by 20 growers, showed the 

 cost of pipe tobacco to be 10.9d. (22 cts.) per pound and £27 Is. ($131.64) per 

 acre, and of cigarette tobacco 11.2d per pound and £40 os. 2d. per acre. 



A Ruakura experiment, P. McConnbxl {Jour. Agr. [^eio Zeal.], 7 {1913), 

 No, S, pp. 252-259, figs. 3). — In a fertilizer experiment with Swedish turnips it 

 is noted that in general phosphatic manures showed better results than any 

 other fertilizer, but in conjunction with kainit lower yields were obtained 

 than when superphosphate was used alone. " This may to some extent be ac- 

 counted for by the fact that when the seeds and manures were sown there was 

 not sufficient moisture in the soil to dissolve the injurious salts in the kainit, 

 resulting in an injury to the germination ; and it is a well-known fact that 

 potassic manures are better applied some time previous to the sowing of the 

 seed. It will also be noticed that the basic superphosphate and sulphur and the 

 basic slag and sulphur plats have given a greater yield than the basic slag and 

 kainit or basic slag and basic superphosphate plats. The addition of sulphur has, 

 however, considerably increased the cost, and it seems strange that sulphur 

 should be so dear in a country where it is so plentiful." 



On the physiology of germination in connection with internal factors in 

 wheat, H. Nilsson-Ehle {Ztschr. Pflanzonzucht., 2 {1914), No. 2, pp. 153-187, 

 pi. 1). — Based upon the assumption that the red and white color factors of the 

 wheat kernels were coupled with the germinative resistance of new wheat, the 

 author announces the following conclusions from results of several years of 

 experimenting: 



The ability of a wheat to germinate quickly or slowly after maturity (germi- 

 nation resistance to weather conditions) was found to be a variety character- 

 istic, segregating in the customary manner in hybrids. This physiological
