ain. Tubers are uni- 
form in shape, oblong, with two good ends, slightly flattened; 
creamy white skin absolutely free from disease and with pure 
white flesh of excellent quality. Well adapted to northern Iati- 
tudes where rainfall is abundant and the temperature not 
excessively high. As a rule, they do not succeed as well as the 
Rural group where they are subjected to unfavorable conditions 
during the time they are forming tubers. 
The Katahdin was originated from a seed-ball by the 
U. S. Department of Agriculture at its experimental station at 
Presque Isle, Maine. It is a handsome shallow-eyed, glossy, 
white-skinned variety which matures a little later than Green 
Mountain, but earlier than the Rurals. It has very few tubers 
of unmarketable size and has all varieties beaten in uniformity 
of shape, size, and in general appearance. It does well on light, 
friable soil, but is not adapted to heavy soil subject to drought 
conditions. 
The Ontario was introduced by the Cornell Agri- 
cultural Experiment Station in 1944 after many years of ex- 
perimental work by Dr. F. M. Blodgett of the Plant Pathology 
Department. It matures as Jate as the Rural and Russet Rural 
and is resistant to scab, late blight and “Z” disease. Wide 
adaptation; tubers very smooth, white and slightly elongated. 
A very promising variety and recommended especially for the 
small grower. 
Originated by the U. S. Department of Agriculture. A 
high-yielding variety somewhat later than the Rurals. Smooth, 
white shallow-eyed tubers thicker than Chippewa and of high 
table quality. Large, vigorous foliage resistant to heat and 
drought, blight, yellow dwarf and scab. Especially desirable 
where blight occurs frequently or where spraying is omitted. 
r The Sequoia is a new selection from a cross of Green 
Mountains and Katahdins that matures Jater than the Rurals 
and Sebago. Tubers are large and oval flattened. Plants are 
very resistant to drought, heat, foliage insects and blight, and 
have usually outyielded other varieties. Adapted to a wide 
range of soil and climate. Should be planted close in row and 
not over-fertilized. Desirable for the small grower who does 
not have spraying or dusting equipment. 
oth The Smooth Rural group includes a large 
number of strong-growing, late-maturing varieties such as Sir 
Walter Raleigh, Rural New Yorker No. 2, Carman No. 3, 
Heavy-weight, and Pioneer Rural. They are practically iden- 
tical. The tubers are white, oval flattened, and regular in form. 
Collectively they are often referred to as “blue sprout” Potatoes. 
Recommended for heavier soils and where Potatoes are grown 
under least favorable conditions. Tolerant of heat and drought; 
tubers keep well in storage and are slow to sprout in the spring. 
Table quality is excellent.
