446 EXPERIMENT STATION RECORD. 



The effect of sterilizing soil on the growth of root tubercles of cowpeas, M. 

 H. Beckwith ( Delaware Sta. Bpt. 1806, pp. 108, 100). — The plants were grown in pots 

 in a greenhouse on sterilized soils. They made a weak growth and produced no 

 nodules upon the roots. 



Catch crops after winter barley (Braunschweig, landw. Ztg., 65 (1897), No. 36, 

 p. 161). — A discussion of how lupines and vetches may be grown after winter barley 

 for green manuring. 



Catch crops and their culture (Farm and Home, 16 (ISO}), No. S12, p. 325). — Notes 

 on clover and rye grass, mustard and rape, rye and vetches, rye, ox cabbage, and 

 rye grasses. 



Fodder crops, J. WitlGHTSON (Ayr. Gag. [London], 46 (1897), No. 1237, pp. 272, 

 273). — Cultural notes on crimson clover, winter rye, and winter vetches. 



Principles underlying forage culture, E. Gross (FUhling's landiv. Ztg., 46 (1S07), 

 No. 18, pp. 539-553). — Notes on forage culture and tabulated results of seed tests. 



The culture of some forage plants, ThSmsgen (Ztschr. landw. Yer. Hissen, 1897, 

 No. 35, pp. 315, 316). — Notes on kidney vetch, hairy vetch, serradella, Jerusalem 

 artichoke, carrots, and lupines. 



The influence of fertilizer on the quantity and quality of forage, C. Dusserre 

 (Chron. Agr. Canton Vaud, 10 (1897), No. IS, pp. 491-403). — A report on experiments. 

 The forage from the manured held was richer in nitrogenous matter, carbohydrates, 

 and ash, and a little poorer in fats than the forage from the unmanured held. The 

 manured held produced the largest crop.

 30, figs. 4). — Reprinted from Bulletin 47 of the station (E. S. R., 8, p. 586).

 The article treats of the hop production in 1897. 



Maize growing on scrub lands, A. .1. Boyd (Queensland Agr. .Join-., 1 (189"} ), No. 

 2, pp. 92-96). — Notes on clearing the land and directions how to grow and utilize the 

 crop of maize. 



Potatoes; variety tests in 1896; potato implements, S. B. Green (Minnesota 

 Sta. Bpt. 1890, pp. 419-440, figs. l?).—k reprint <>f Bulletin 52 of the station (E. S. R.,

 No. 16, Suppl., pp. 89-96). — A discussion of the culture of sugar cane and its natural 

 requirements. The manufacture of sugar as carried on in that country is described. 



Manuring for wheat (Sachs, landtv. Ztschr., 45 1 1891 I, No. 34, pp. 481, (82). 



Results of experiments at the San Juan Substation, II. H. Grifein (New 

 Mexico Sta. /-'»/. 21, pp. 18). — This bulletin includes popular notes on the fertiliza- 

 tion of sandy soils by leguminous plants, giving the results of growing several 

 varieties of legumes at the substation : results of a successful test of potassium sul- 

 phide for the prevention of the loose smut of oats; a verification of the use of cor- 

 rosive sublimate for the prevention of potato scab ; popular and remedial notes on 

 the squash bug (Anasa tristis), the Colorado potato beetle, tomato worm, and New

 Bpt. 1896, pp. 83-111). — An experiment in the subirrigation of toma- 

 toes is noted. At the time the report was made the surface- watered 

 plants gave indications of better results than snbirrigated ones, but no
