The value of Aroos- 
took-grown Seed Pota- 
toes IS unquestionable. 
The Certification De- 
partment of the State of 
Mame plans to safeguard 
the interests of the seed- 
buyers. Two field in- 
spections are made dur- 
ing the growing season 
and one at digging-time. 
While each carload is 
being graded, an inspec- 
tor visits several times. 
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 m shape, eyes 
very shallow. Very heavy yielder. 
Bliss Triumph. This season we will be able to supply 
Maine-grown Certified Bliss Triumphs. An early, 
deep red, round, very smooth variety and a fine 
quality cooker. Planted extensively in the South. 
Russet. 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. Russet outyielded other varieties 
two to one in many sections last season, planted 
side by side.

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 outytelds Cobblers wherever 
planted. You will not go wrong in planting some of 
this variety. 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. It is very late 
and quite blight-resistant. Some growers do not plan 
to spray them much, if any, but 1f sprayed they will 
continue to grow until the frost gets them, conse- 
quently a greater yield of fine-appearing tubers. 
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 believe it will find its place 
above all others. Excellent for bakers. See Price-List. 
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. The crop is ready about 10 days earlier 
than Early Rose. Vines are very stocky, vigorous, 
and not as liable to be affected with blight or suffer 
drought as most other varieties. Owing to the fact 
that the Cobbler withstood the severe drought last 
season better than other sorts, it is probable that 
there will be a larger demand than usual this season. 
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. Shippers prefer this 
variety and frequently pay a premium for it. Best 
for loose and muck soils, and especially adapted for 
northern states. Plant Improved Green Mountains 
and increase your profits.
