200 lbs. basic slag and 200 lbs. nitrate of soda ; on the third 25.39 tons from 

 400 lbs. calcium nitrate and 100 lbs. sui:)eri)hGsphate of lime; and on the fourth 

 30.83 tons from 200 lbs. sulphate of ammonia, 100 lbs. bone meal, and 50 lbs. 

 sulphate of potash. Analyses are given of the cane juice from 2 of the estates. 



Sugar cane in South Africa, II. J. C'noLts (Agr. Jour. Union So. Africa, o 

 {1913), Nos. 2, pp. 188-204, fli/- 1; 3, pp. J,05-Jil8; //, pp. 575-583; 5, pp. 7^6- 

 153). — The author describes melhctds of propagation, field operations, etc. 



Experiments on manuring tobacco in Hungary, K. Kebpely (Dohdny Njsdg, 

 SO {1913), No. 2, pp. 2-4; abs. in Intemat. In.sl. Agr. [Rome], Mo. Bill. Agr. 

 Intel, and Plant Diacascs, 4 {1913), No. 3, pp. 411-413).— In these experiments 

 improvement in the combustibility of the leaves was noticeable, which was 

 attributed to the use of nitrate of soda in 2 applications, after the first and 

 second hoein;^'s. Lime from sugar factories resulted in increased yields from 

 a soil that contained 0.112 per cent of lime. 



Yield and quality in wheat, A. and Gabrielle L. C. Howard and H. M. 

 Leake {Agr. Jour. India, 8 {1913), No. 2, pp. 128-138, fig. 1).— This compares 

 the advantages derived from wheat growing by hot weather cultivation, which 

 conserves the moisture after the monsoons, with those from drainage, which 

 prevents " water logging " of the soil during the monsoons. The former method 

 increased the wheat yield from 32.02 to 37.89 bu. per acre in 1910, and from 

 22.9 to 35.41 bu. in 1911, while the method of drainage increased the yield from 

 15.55 to 34.45 bu. per acre. The large yields were invariably of better quality 

 than the others. 



Wheat storage, T. Sanderson {North Dakota Sta. Spec. Bui., 2 {1913), No. 

 2(/, pp. 350-352). — Winter and spring wheats stored in bins usually showed a 

 continual loss in weight up to 4 years, due to moisture and to wearing off of 

 seed coat in handling. The losses ranged up to 2.54 i)er cent, but in some cases 

 there was a slight increase in weight. Data on 34 samples are given, in some 

 cases covering 4 years. 



The change in weight of grain in arid regions during storage, F. S. Harris 

 and G. Thomas {Utah Sta. Bui. 130 {1914), pp. 305-313, figs. i(?).— Results of 

 storing wheat and oats in sacks and weighing every month for 2 years show 

 that " contrary to popular opinion, there is a gain of from 2^ to 4i per ecnt 

 instead of a loss in the weight of grain during the fall after harvest. While 

 this holds for Cache Valley, Utah, other conditions would probably not give 

 just the same results. . . . The method of raising or harvesting grain did not 

 seem to have as much effect on the change in weight as the temperature and 

 humidity. In every case there was a gain in weight during the winter, and a 

 loss during the summer, but the grain weighed less at threshing than at any 

 time later." 



Salting Canada thistles, A. J. Blackman {Breder's Gaz., 64 {1913), No. 8, p. 

 311). — This describes a successful method of eradicating this weed by the ap- 

 plication of salt to the plant while it is moist with dew or rain. 



HORTICULTURE. 



Making special crops pay, D. Utter {New York, Springfield, Mass.. and 

 Chicago, 1913, pp. 60, pis. 16, figs. 2). — A practical treatise on the culture of 

 the more important truck crops. 



Truck crops for south Mississippi, E. B. Ferris {Mississippi Sta. Bui. 163 

 {1913), pp. 24^. — In order to show the results to be expected from growing 

 various fruits and vegetables on the cut-over lands of south Mississippi, the 

 author here summarizes the results that have been secured from experiments 

 made at the McNeill substation.
