line, giant beggar weed, sugar beets, carrots, ruta bagas, mangel wur- 

 zels, turnips, and Jerusalem artichokes. The millets, Panicurn crus- 

 galli, I', mileaeea, P. italica, Goldeu Winter and New Siberian, yielded 

 about 1G, 10, 7, 9, and 5 tons of hay per acre, respectively. It was 

 found that soybeans responded readily to fertilizers supplying potash, 

 phosphoric acid, nitrogen, and lime. Of 5 varieties of cowpeas, South- 

 ern Yellow Eye produced the best yield — over 18 tons of green material 

 per acre. The average yield of Russian vetch ( Vicia villosa) was over 

 13 tons of green fodder per acre. The results with crimson clover have 

 been reported in a former bulletin (B. S. R., 8, p. 586). Thousand - 

 headed kale, sown in spring and cut in August, yielded about 24 tons of 

 green fodder per acre. The yields of the root crops are given in a table. 



Forage crops, E. B. Voorhees and C. B. Lane (New Jersey Stas. 

 Bui. 130, pp. 1-16, pis. 2). — The results of experiments with forage 

 crops conducted for 3 years are reported, and the methods used in 

 seeding and the cost and composition of the fertilizers applied are dis- 

 cussed in a popular manner. The following forage crops, arranged in 

 the order of their use during the season, were grown at the station: 

 Rye, crimson clover, red clover, mixed grasses, oats and peas, corn, 

 cowpeas and soy beans, Japanese millet, and barley and peas. The 

 laud on which these crops were grown received a geueral application 

 of 8 tons of barnyard manure per acre annually. In addition to this 

 application the crimson clover, corn, cowpeas, and soy beans received 

 a dressing of 200 lbs. per acre of an even mixture of ground bone, acid 

 phosphate, and muriate of potash; the millets, oats and peas, and bar- 

 ley and peas, an application of 200 lbs. per acre of a mixture of 50 lbs. 

 nitrate of soda, 100 lbs. of acid phosphate, 100 lbs. of ground bone, and 

 50 lbs. muriate of potash. The cost of the fertilizers for these crops 

 was $2.50 per acre. The rye received a dressing of 100 lbs. acid phos- 

 phate and 50 lbs. muriate of potash per acre, applied immediately 

 before seeding. The cost of this application was #1.50 per acre. 



The digestible food and its cost of production in the various crops as 

 determined in these experiments is given in the following table, the 

 object of the analysis being to determine the average composition of 

 each crop at the stage best fitted for feeding:
