EXPERIMENT STATION BULLETINS. 219 



in an ordinary cellar and the remainder had been left in the field without 

 digging. The ground was deeply covered with snow all winter, which 

 prevented any injury to the tubers from frost. These lots were planted 

 side by side, but there was no ditference in germination or growth, show- 

 ing that if the ground is thoroughly protected by snow, potatoes are not 

 injured when left until spring. As a general practice, it would be 

 hazardous except in the extreme north. 



The season was so wet and cold that the late varieties made a rather 

 poor showing. The potato blights were quite troublesome in some locali- 

 ties but by thorough spraying with Bordeaux mixture, the crop was very 

 free from these diseases. The tubers were very free from scab, the seed 

 having been treated with the corrosive sublimate treatment. The notes 

 will onlv include some of the best of the newer varieties and those arown 

 this season for the first time. The new varieties are as follows: 



Arcadia is one of the most promising. It yielded 251.38 bushels })er 

 acre. The vines are upright, rank growers, tubers oval to* roundish, 

 flattened in shape. The color is a delicate pinkish white, eyes shallow, 

 giving them a smooth surface. The quality is good. It matured among 

 the earliest varieties. 



Hewes yielded 290.26 bu. per acre. The vines were strong growers and 

 the tubers are of good (piality and are well bunched in the hill. It is 

 of the Ohio type in season, growth and form. 



Prince Edward, is of the Rose type and gave a yield of 155.49 bu. per 

 acre. The tubers are of good quality and resemljle the Early Rose in 

 shape and color, but the vines are not as strong growers. They matured 

 a little later than the Early Ohio. 



Rose of the North gave the third heaviest yield (451.91 bu. per acre), 

 among the early varieties. It is not a strictly early sort but ranked as a 

 second early. The tubers are elongated, little flattened; eyes shallow, 

 slightly pink in color. The vines are branching, thrifty growers and 

 mature very evenly. The quality of the tubers is excellent and they 

 appear to be good keepers. 



Among the early varieties or those ripening with Early Ohio, are 

 several promising sorts. 



Coles is a very attractive and desirable early sort. It has been grown 

 here three years and gives an average vield of 225.89 bu. per acre. In 

 1902 it yielded 300.62 bu. per acre. 



Eureka received from Burpee in 1902. averages 272.06 bu.. yielding 

 378.37 bu. in 1903. It has a clear white slightly netted skin. 



Michigan still holds its place as one of the leading early white potatoes. 

 In 1903 it yielded 372.19 bu. It has been grown here seven years and 

 gives an average yield of 212.49 bushels per acre. 



Minnehaha shows an average for five years of 229.6 bu. In 1902 it 

 produced 860.22 bu., but the tubers were rather irregular in shape.
