ranging from 215.8 to 350.3 buslieis, according to treatment. The 

 av^erage yield of potatoes in New York for this year was 89 bushels 

 per acre. (See Bulletin 110, p. 389.) 



— In 1897 ten plats averaged at the rate of 322 bosliels per acre, 

 ranging from 236 to 381: according to treatment. The average in 

 the State for this jear was 62 bushels per acre. (See Bulletin 140, 

 p. 390.) 



The experiments of 1898 were similar to those of 1897, and are 

 described in Bulletin 156. The average yield of eleven plats was 

 292.3 bushels per acre, ranging from 206 to 398.6 bushels, according 

 to treatment. 



In 1899 eleven plats averaged at the rate of 195 bushels per acre, 

 ranging from 111 to 233. This crop demands a word of comment. 

 The pliysical condition of the soil now indicates that it is becominor 

 deficient in ormmic matter and it suffers from drouo-ht more than 

 formerly. The thorough preparation and tillage given the plats 

 produced strong vigorous plants in spite of the severe drought of 

 the summer, but an early frost killed the tops before sufficient kite 

 rains had falleji to enable the plants to produce the usually large 

 yield, which, however, seemed assured up to the time of this unfor- 

 tunate event.
