SEED POTATOES 
CULTURE—A sandy loam reas¬ 
onably rich in organic matter is 
considered the very best soil for 
potatoes. However, any soil that is 
light and easily worked and con¬ 
tains a good supply of plant food 
will grow potatoes successfully. It 
is not advisable to apply fresh 
,manure just before the tubers are 
planted. Fresh manure, besides 
causing a number of diseases on 
the tuber, contains too large a 
supply of nitrogen, which pro¬ 
duces too rank a growth at the 
expense of the tubers. 
Certified Seed Irish Pota¬ 
toes. When you purchase 
genuine State Certified Po¬ 
tatoes, you get stock that has 
been inspected by an author¬ 
ized state agent which as¬ 
sures you that this stock is 
free from serious diseases, 
and straight one variety. A 
state certification tag on 
each bag of Certified Pota¬ 
toes. We have Irish Cobblers, Bliss Triumph and Early Ohio in Certified Stock. Prices 
quoted on request. 
IRISH COBBLER 
EARLY OHIO. Favorite variety among 
gardeners everywhere and particularly well 
suited to light or loamy soil, but succeeds 
well anywhere. Tubers are oval, have few 
eyes, smooth white skin, slightly flushed 
with rose and of exceptional quality. 
IRISH COBBLER. This has become one 
of the general favorites in all localities for 
early as well as late planting. The partic¬ 
ular features which impress our many grow¬ 
ers are the general thriftiness of the vines, 
combined with a remarkably large yield of 
fine, most attractive, pure white-skinned 
potatoes. The tubers are of both fine appear¬ 
ance and quality. 
BLISS TRIUMPH. One of the earliest and 
largely planted by truckers and gardeners 
for early crop, being mostly shipped to 
Northern markets, and is highly recommend¬ 
ed. Potatoes round, with deeply indented 
eyes, and of pink skin. 
BURBANK. Of the late Northern sorts, 
this is more largely used than any other. It 
is of good size, oblong shape, and an excell¬ 
ent yielder. The flesh is white, and is very 
mealy, and of fine flavor. 
RURAL NEW YORKER. A valuable va¬ 
riety of large size, very smooth and a great 
cropper. In quality is unexcelled. It is the 
best late keeper and is highly recommended. 
Their large, handsome appearance makes 
them more profitable than any other sort. 
Market prices will be quoted on all seed 
potatoes upon application.
