IT PAYS TO PLANT CLEAN SEED 
The first step in growing potatoes profitably is the planting of 
hardy, disease-free seed from heavy yielding crops. Isbell’s North¬ 
ern Grown Seed Potatoes are famous for their earliness, hardiness, 
freedom from disease, and the big profitable crops they produce. 
The increased yield and better quality of new seed will more than 
offset the cost of the seed and return a good profit besides. 
SHIPPING SEASON. About April 1st, is the earliest date seed 
potatoes can be shipped safely and all orders are booked for ship¬ 
ment after that date. 
Extra Early Eureka 
ISBELL’S NORTHERN GROWN 
SEED POTATOES 
A fine Extra Early White Potato. Extra Early Eureka 
seldom fails to produce fine crops of extra early Potatoes. 
The plant is compact in growth, vigorous and hardy. The 
Potatoes are nearly round, white and very attractive. In 
quality they rank high, being splendid cookers. They ripen 
evenly and will not make a second growth. 
Early Six Weeks 
A fine Potato for the early market. It is extra early and 
one of the best market varieties. The Potatoes begin to 
form when the vines are only 5 to 6 inches high, and in 
7 to 8 weeks from planting are of fine marketable size. 
The tubers are of oval form, light red color, with shallow 
eyes. They cook well even before they are thoroughly ripe 
and have a fine pleasing flavor. 
Irish Cobbler 
The Irish Cobbler is creamy white, nearly round in shape. 
A little later than Ohio, but a heavier yielder. Continued 
heavy crops have earned Irish Cobbler the name of “old 
reliable.’’ Very close planting is possible because of up¬ 
right vine growth. Irish Cobbler is a favorite variety on 
Long Island and in Maine. Also is grown quite extensive¬ 
ly in Michigan. Often grown on muck for a main crop. 
Early Ohio—Red River Grown 
While this is one of the oldest early varieties it is still 
one of the most popular. The skin is light pink and flesh 
white. They are of good size and always smooth. They 
are oval or egg-shaped and very uniform. Many people 
prefer them because of their fine flavor when cooked. Vines 
are hardy, erect and the tubers are set in a compact clump. 
Red River stock is the best seed of this variety produced 
anywhere. 
Idaho Baking Russet 
Also Known as Russet Burbank. 
New 
Katahdin 
I 
Katahdin 
This new Potato was originated in Maine by the U. S 
Dept, of Agriculture. It takes its name from Mt. Katahdir 
near which it was developed. The government has spenl 
$250,000.00 during the last eight years in producing this 
new variety. 
Katahdin is a round or slightly oval white Potato, verj 
smooth, with very shallow eyes. The vines are light green 
and vigorous. So far no trace of mosaic has been found on 
plants of Katahdin. It ripens about a week earlier than 
Late Petoskey and White Rural., It has consistently out- , 
yielded Rural New Yorker and Green Mountain, and grades; ' 
out with a smaller per cent of No. 2 grade and culls. The 1 ' 
type is very uniform and in cooking and eating qualities it ' 
is unsurpassed. Katahdin does well on rich peat soils and ( 
on muck. 
Rural New Yorker or White Rural 
This has been a standard late White Potato for many 
years and is still being grown extensively. Is a vigorous 
and thrifty grower and one of the heaviest yielders. Tubers 
are slightly oval, smooth and have a very white skin. Good 
winter keeper and of fine cooking quality. 
Late Petoskey or Russet Rural 
This variety has been the standard late variety of Mich¬ 
igan but of late is losing favor somewhat because it is not 
as white in color as the market demands. When grown 
on light colored sandy soils, the skin very light in color 
and it has a fine appearance. When grown on dark loam 
or clay soils, the color is not so good. It is recognized as 
the best winter keeper and as one of the heaviest yielding 
sorts as well as a good cooking variety. 
Potato Seed (hybridized) 
It is the finest baking and cooking potato known and for 
this reason is well worth raising. Idaho Baking Russet is 
a late Potato of vigorous habit of growth. The tubers are 
long and taper toward each end. They are almost perfectly 
smooth with very shallow eyes. They have a thick russet 
skin which protects them and makes them the best of all- 
winter keepers. They have the finest flavor ever found in 
a Potato. Western growers have been shipping Idaho Bak¬ 
ing Russets to eastern markets for several years with won- 
Practically every seed produces a distinct variety. Many 
of the choicest varieties have been originated by amateurs 
from Potato Seed. They have an equal chance with the 
Potato specialist, as Nature does the work. Fame and . 
fortune wait the originator of varieties that are distinct 
and better in certain respects than those now on the mar¬ 
ket. Further, the growing of Potatoes from the true seed 
is very interesting work. Directions for planting and culti¬ 
vating on every packet. Pkt., 15c. 
derful success.

This wonderful new Potato is more than a week earlier 
than any other sort and outyields all other early varieties. 
Under favorable conditions it has yielded 400 bushels per 
acre. In appearance it is most attractive as the tubers are 
large, oval and white with shallow eyes and smooth skin. 
Cooks dry and mealy and has the finest flavor imaginable 
in a Potato. It originated from a seedling in Northern Minne¬ 
sota, a district noted for fine Potatoes. For the first two 
years after its introduction we were unable 
to supply the demand for this seed even at 
the high prices which prevailed at that 
time. We have received hundreds of letters 
from our customers in many states who 
have grown this variety and are delighted 
with it but space will not permit publish¬ 
ing them here. This year the seed is lower 
in price and within reach of every¬ 
one. Our seed was grown from the 
originator’s stock and is true and 
reliable.

M. L. Long of Ohio writes'—The 
Katahdin and White Gold Potatoes 
made a good crop and they are as good 
as you say. Find quality and hardly 
any small ones. I am well pleased.
