Valuable Hints on Growing 
GOOD POTATO CROPS 
1. Test your soil. 
2. Fertilize well. 
. Use good certified seed. 
Dip your seed. This always pays. 
. Plant at least 20 bushels per acre. 
6. Use a good planter. Skips cost money. 
7. Do not expose cut seed too long 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 Iate. 
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 inclined to be shaped round. This 
Potato is yearly increasing in popularity for early 
markets. We advise ordering early. 
Improved Green Mountain. This variety has proved 
to be the surest cropper and a most profitable sort 
to grow. The skin is pure white, slightly netted, and 
the quality is among the best. Keeps excellently and 
its fine table qualities make it one of the foremost 
sorts in the large city markets. Best for loose and 
muck soils, and especially adapted for northern 
states. Plant Improved Green Mountains and in- 
crease your profits. 
Katahdin. This new Potato, introduced by the Maine 
Experiment Station, promises to be an outstanding 
variety. Matures about midway between the Cob- 
bler and Green Mountain. Round in shape, eyes 
very shallow. Very heavy yielder. 
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 60 to 75 bushels. Free pamphlet. Postpaid, 2 ozs. 50c; 
Ib. $2.00.

are now coming up. I was very much pleased with them.’’
