FIELD CROPS. 35 



Cooperative experiments of the department of agronomy, M. F. Millkk 

 ami ('. i;. IIuixiii.soN [Missouri .S7(/. Circ. M, in>. 11). — This circular is de- 

 siijnod to furnish directions to the farmers cooperuting with the state station 

 in the experiments with alfalfa, corn, oats, wheat, barley, grasses, clovers, and 

 potatoes. 



Distribution of seeds and plants, E. J. Wickson and R. E. Manskll {Call- 

 foniia l^ta. ticvd Bui. IU0!)-1(), pi). (J). — This re!)orts the number of packages of 

 seed distributed since 1!)(>2. outlines the aims and methods of the distribution, 

 and lists the seeds now available for that puri»ose. 



Development and standing of German agricultural plant breeding, P. 

 lIii.LMANN {Joliib. Dvul. Ldiidtv. Grscll., 2'/ (I'JOU), No. 1, pp. 1-9). — These 

 pages contain a review of the i)rincipal work of German plant breeders for the 

 past year and an estimate of the influence of the German agricultural society. 



The velvet bean, J. M. Scott (Florida 8ta. Bui. 102, pp. 45-56, 57, 58, figa. 

 S). — Continuing previous work on this subject (E. S. II., 13, pp. 1042, 1075), a 

 brief historical sketch of the velvet bean is followed by directions as to the time 

 and method of i)lanting, seed selection, cultivation, and harvesting, a discussion of 

 its use as seed and as a soil renovator, and a report of experimental work 

 with the crop. 



When planted from 10 to 15 in. in the drill in rows 4 ft. apart, 1 bu. of seed 

 planted 4 acres and 2,258 lbs. of beans in the pod or 22.5 bu. of shelled beans 

 were harvested per acre, while when planted in rows 8 ft. apart, alternating 

 with corn rows, the yield was 20.3 bu. of shelled beans per acre in addition to 

 the yield of corn. 



Plats fertilized with dried blood, acid phosphate, and muriate of potash, 

 separately or in various mixtui-es, usually failed to produce as high yield as the 

 unfertilized plats. The few increased yields were obtained at an economic loss. 



Paris green at the rate of from 1 to 3 lbs. per acre has been found effective 

 as a means of preventing injury from the caterpillar of Anticarsia gcmmatilts. 



Crimson clover, J. F. Duggar (Alahama Col. Sta. Bui. 147, pp. 105-129, 

 figs. 3). — The cultural recpiirements of crimson clover in Alabama and its value 

 as a nitrogen gatherer are discussed and directions given for securing a stand. 

 On reddish, sandy upland loam soil, of the Cecil series, the inoculated crop 

 produced 0,100 lbs. of hay per acre, while the uninoculated produced no har- 

 vestable crop. On Norfolk sandy loam, the yield was estimated at 1 ton of 

 hay i)er acre after inoculation, while the plants on the uninoculated plats had 

 no tubercles, were yellowish, and either died without blooming or bloomed at 

 a height of 2 to 6 in. Results of earlier tests with pure cultures (E. S. It., t), 

 p. 743; 10, p. 837) are reprinted. 



Broom corn, W. R. Perkins (Mississippi Sta. Bui. 134, PP' 5). — The charac- 

 teristics, varieties, and cultural requirements of broom corn are discussed and 

 directions given for seed selection, planting, cultivation, harvesting, strii)ping, 

 curing, baling, and storing. 



American export corn (maize) in Europe, J. D. Shan ah an, C. E. Leighty, 

 and E. G. Boerner (U. 8. Dcpt. Agr., Bur. I'lant Indus. Circ. 55, pp. 4*, flffs- 7). — 

 This circular reports the observations made during 1906, 1907, and 1908 ou 

 wheat arriving at European markets from the principal American ports. 



Data were gathered with regard to 1.5,077,987 bu. of corn, of which 12.7 per 

 cent was heating or hot on arrival. In 8 cases the entire parcel or cargo was 

 hot or heating. All of this corn was certificated as No. 2 corn. No. 2 corn sail 

 grade, or prime (sail) mixed corn. The ipiality and condition requirements of 

 tliese grades are similar. Tal)ulated data and charts are given as to the 

 condition of the various cargoes.
