Kennebec 
A Valuable New Variety 
The discovery of Kennebec marked the climax in a 
potato hunt that has taken years and years. Like any- 
thing else, an absolutely perfect potato may never be 
created and different regions are sure to have local fa- 
vorites. But a survival of the fittest race is going on 
among the potatoes and just now the Kennebec looks like 
a winner. The introduction of this variety brings us a 
potato that will resist late blight and scientists have added 
so many other good features that the Kennebec, judged 
by tests, is the nearest yet to a super spud. It is a late 
potato in its native state and is best described as a vig- 
orous, fast growing, high yielding, late maturing variety 
of high quality and is notably resistant to late blight as 
well as other troublesome diseases. The Kennebec is a 
very recent introduction but it is already crowding some 
of the so-called leading varieties. 
Potato yields in Maine are watched closely and each 
season seems to bring a new record. None have surpassed 
the Kennebec; it has produced yields of 900 bushels per 
acre. 
Many plantings of this variety have been made in 
Southern New England and it seems that this new potato 
is well adapted to many types of soil as heavy yields 
have been reported in each case. The quality is excellent; 
it is a white variety and compares very favorably with 
the Green Mountain which has been a leading variety for 
many years. The tubers have shallow eyes and a white 
skin. The shape, slightly oblong, is a little shorter than 
the Green Mountain. 
Cobbler 
Green Mountain 
This is one of the old standard varieties and because of 
quality and yield it has been the main crop variety in 
Aroostook County, Maine, where most of our New Eng- 
land certified seed is produced. 
The Green Mountain has so many good qualities that 
for the past several years it has seemed impossible to 
produce a variety to succeed it. It is a late crop winter 
potato and an excellent. potato for baking and a very 
dependable keeper. It seems to thrive on all types of soil 
and produces a heavy crop. The skin is white and the 
potatoes cook white and mealy. Most crops produce po- 
tatoes of a very satisfactory size for home use or for the 
market. :

Pontiac 
A New Red Potato 
This is a new variety just being offered for the general 
trade. It is very similar to the Bliss Triumph in color but 
it is a much heavier yielder. It is one of the best red 
varieties ever introduced and under usual conditions will 
produce a heavy crop of marketable, smooth, red pota- 
toes of excellent quality. The shape is slightly oblong. 
This is the only red skinned potato we offer. 
irish Cobbler 
An early, white-skinned variety; very short, thick, in- 
clining to round. This potato has continued to gain in 
popularity as the variety for the early market. It is still 
the best early potato both in quality and yield. Very few 
others even equal and none surpass the Cobbler in yield 
unless it is some of the main later varieties For home 
garden planting it is a wonderful sort, giving the gardener 
a good crop of early potatoes of unsurpassed quality. It 
does have a deeper eye than most varieties and some 
obiect to this, but this defect is made up by earliness and 
quality. The vine is very strong and vigorous and is quite 
resistant to blight and other potato plant diseases. A very 
fine old variety. 
Katahdin 
Originated by the U. S. Department of Agriculture, the 
Katahdin has become the outstanding late potato for 
storage and market. It was originated in Maine and has 
been bred for disease resistance, quality and yield. Dur- 
ing the years it was under observation it was entirely 
free from mild mosaic. It has increased in yield until it 
has surpassed about all of the late producing varieties. 
The tubers are smooth, short. elliptical to roundish, and 
have few very small, shallow eyes. The crisp white flesh 
has a distinct cooking quality which appeals to the house- 
wife. 
Green 
Potato Culture 
The potatoes should be cut into pieces having 2 or 3 
eyes. Plant in furrows 3 feet apart and from 8 to 12 inches 
apart in the furrows. One peck (15 lbs.) should be suffi- 
cient to plant 75 to 100 pieces. It should take about 14 
bushels to plant one acre. Potatoes do best on new soil 
but may be grown on good garden soil and will respond 
generously to a liberal application of fertilizer. Cultivate 
by bringing the soil well up around the plant. Spray or 
dust the plants for insects and blight.
