72 AGRICULTURAL EXPERIMENT STATION. [Jan. 



represented, September 21st, a dense green mass from two 

 and a half to three feet high, with runners frequently from 

 five to six feet long. Most of them were, at that period, in 

 full blossom, and some matured subsequently a few pods. 



The Clay and Whippoorwill seemed, on the whole, with 

 us, the leading varieties ; all varieties suffered severely from 

 the first frost, October 8th. They were relished as fodder 

 by cows, in the green as well as the dried state. 



Experiments in this direction will be continued. A vari- 

 ety maturing three weeks earlier has been promised by a 

 friend in North Carolina for the coming season. 



Three analyses of Cow Peas, raised on another occasion, 

 will be found in the Second Annual Report, pages 91-93. 



Aside from the previously described observations, some 

 interesting facts have been obtained during the past season 

 with regard to the cultivation of Vetches ( Vicia sativa) , 

 Serradella ( Ornithopus sativus, Brot. ) , Saintfoin or Es- 

 parsette {Onobrychis sativa), Blue and Yellow Lupine, 

 Evergreen Millet (Denver, Colorado), Summer Rape and 

 Winter Rape (Brassica napus).

Experiments with Potatoes. 



Var. : Beauty of Hebrox. 



The arrangement of the field, the mode of manuring, and 

 the variety of potatoes raised have been the same as in the 

 preceding season. (See Second Annual Report, pp. 87-89.) 

 The three plats set aside for the experiment, each one-fifth 

 of an acre in size, were prepared for the experiment, and 

 planted April 27th. Pint No. 1 received, as fertilizer, thirty 

 pounds of muriate of potash and one hundred and thirty 

 pounds of steamed fine-ground bones ; Plat No. 2 received 

 no fertilizer; Plat No. 3 was fertilized with fifty-eight 

 povuids of potassa-magnesia sulphate and one hundred 

 and twenty pounds of fine-ground bones. The rows were 

 three feet and three inches apart, and the seed potatoes 

 dropped from eighteen to twenty-four inches in the rows. 

 One-half of each plat was planted with medium-sized whole 

 potatoes ; one-half with half a potato in the spot.
