60 EXPERIMENT STATION. [Jan. 



It will be seen tliat most of the varieties gave a fairly 

 satisfactory yield. Four only gave a yield of merchantable 

 tubers in excess of 200 bushels ; these, in the order of their 

 rank, were: Climax, Chenango White, Hammond's Wonder- 

 ful and Simmon's Model. Four varieties gave a yield at 

 the rate of less than 100 bushels of merchantable tubers per 

 acre ; these, in the order of their inferiority, were : Uncle 

 Gideon's Quick Lunch, Good as Gold, Short Seasons and 

 Noroton Beauty. 



The seed of all the varieties was treated with formalin, 

 and the product was free from scab. They were twice 

 sprayed with Bordeaux mixture. The varieties showing 

 blight earliest were Good as Gold, Uncle Gideon's Quick 

 Lunch and Noroton Beauty. All the vines of these varieties 

 w^ere dead on August 14, on which date Salzer's Sunlight, 

 Climax and Clark's Pride were beginning to show blight. 

 The six varieties named were the only ones apparently much 

 affected. Among these varieties, all except Climax gave a 

 small yield, those earliest blighted being among the very 

 poorest. 



XII. — Poultry Experiments. 



The poultry work of the past year has been a repetition 

 of the feeding experiments of the preceding year. These 

 experiments had indicated : first, that, provided fat is abun- 

 dant in the ration, high protein content is not essential; 

 second, that, if the fat content of the ration is low, a large 

 proportion of protein in the feeds used appears to be much 

 more essential ; and third, that a large proportion of fiber 

 in the ration used is unfavorable to a good egg product. 

 The fowls vised in the experiment this year, as last, were 

 pullets of our own raising; and in comparing different food 

 combinations, carefully matched flocks have been kept, as in 

 former years, each in a house by itself, all the houses being 

 of precisely similar dimensions and construction. 



1. The fowls in houses Xos. 1 and 2 have been fed on 

 rations characterized by high content both of ash and fat 

 and low fiber. As wheat is relatively deficient in fat, the 

 ration in which it is largely used received an addition of
