Maine Seed Potatoes 
Irish Cobbler. An early, white-skinned variety, very 
short, thick and inclined to be shaped round. This 
Potato is yearly increasing in popularity for early 
markets. We advise ordering early. 
Katahdin. Introduced by the Maine Experiment 
Station; promises’to be an outstanding variety. Ma- 
tures about midway between the Cobbler and Green 
Mountain. Round in shape, eyes very shallow. Very 
heavy yielder. 
Kennebec. This is a new variety, highly resistant to 
late blight, wild mosaic, and net necrosis. It Is a very 
vigorous, high-yielding, Iate-maturing variety. In 
tests for five years at Presque Isle, Maine, it out- 
yielded Katahdin by 97 bushels per acre. It also 
produced the highest percentage of U.S. No. 1 
Potatoes. See Price-List. 
Russet, Michigan Certified. One of the best for main- 
crop cultivation. Similar to the Raleigh in shape of 
tuber but has a russet skin and few eyes. This is a 
very hardy sort and usually produces good yields, 
even when seasons are unfavorable. Vines grow 
vigorously, have fine blight-resisting qualities, and 
usually remain green until late in fall.
