. Do not expose cut seed too Jong to the sun. 
Poor stands are often caused by over-exposure 
and drying. 
8. Keep insects under control. Spray often and 
well. Half spraying is not much better than 
none at all. Spray early and spray late. 
9. Dig carefully (avoid bruising); sound Potatoes 
keep better. 
10. Store in a dry place. 
Bliss Triumph. This season we will be able to supply 
Maine-growr. Certified Bliss Triumphs. An early, 
deep red, round, very smooth variety and a fine 
quality cooker. Planted extensively in the South. 
Irish Cobbler. An early, white-skinned variety, very 
short, thick and mclined 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, Jate-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 UWiSa eNom 
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. Vimes grow 
vigorously, have fine blight-resisting qualities, and 
usually remain green until late in fall. 
Semesan Bel 
Better Potato-yields with Improved Semesan Bel. Tests in 
15 states have proved that any Potato-grower can_usually 
expect better returns from his seed if he treats it with Semesan 
Bel before planting. Results in lower grading cost and more 
profit. Treat your seed as fast as you can dip it. One pound 
treats a to 75 bushels. Free pamphlet. Postpaid, 2 ozs. 50c; 
ib. $2.30. 
We will appreciate good pictures showing excep- 
tional results from our seeds and are willing to pay 
for any that we can use in our catalog.
