The value of Aroos- 
took-grown Seed Pota- 
toes is unquestionable. 
The Certification De- 
partment of the State of 
Maine 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 in 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. 
IRusset, Michigan Certified. One of the best for main- 
crop cultivation. Similar to the Raleigh m 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 Iate in fall. Russet out- 
yielded other varieties two to one In many sections 
last season, planted side by side.

TUBERTONE 

TUBERTONE is the special powder for seed treat- 
ment of potatoes on a large scale (one acre or more). 
Dust each bushel of cut seed potatoes with one-half 
pound of TUBERTONE. 
Produces larger, more uniform crops with more No. 1 
grade potatoes. 10-Ib. bag (enough for 1 acre) $5.00; 
50-Ib. lot (enough for 5 acres) $22.50. 

Here in Lancaster County, Mr. Leroy Stoltzfus of Leola got 
38 more bushels per acre on his Sebago Potatoes as a result of 
TUBERTONE treatment. Naturally, he was very pleased 
over this increase. 


Vermont Certified Green Mountains. The last few 
years we have sold a limited amount of Certified 
Vermont Green Mountains. Some growers report 
better crops from Vermont Mountains than the 
Maine. We can furnish Vermont seed as Jong as our 
supply lasts. 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 if 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.
