Maine Seed Potatoes 

Chippewa. One of the newest varieties introduced by 
the Maine Agricultural Experiment Station. Matures 
a trifle later than the Cobblers, but earlier than the 
Katahdins. Round in shape. Skin very smooth; 
shallow eyes. Usually outyields Cobblers wherever 
planted. See Price-List. 
SEBAGO. One of the newest varieties from the Maine 
Experimental Farm. Sebago carries a purple bloom 
and has a very rugged top and stock. Many reported 
that Sebago lived through the dry weather and was 
able to make good crops after the late rains. In many 
places it has outyielded any other variety, and we be- 
lieve it will find its place above all others. Excellent 
for bakers. See Price-List. 
Erish 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 increase your 
profits. 
Katahdin. This new Potato, introduced by the Maine 
Experiment Station, promises to be an outstanding 
variety. Matures about midway between the 
Cobbler 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. 30c; 
Ib. $1.65; 5 Ibs. $7.15.
