SEED POTATOES 
from the 
RUGGED NORTH 
Letters and records from users time and time again prove the extra¬ 
ordinary value of Certified Seed. It has been known that, in some 
instances dealers offer so-called “Certified Seed” which is only private, 
ly inspected and approved. It, therefore, behooves every grower to 
positively know the origin and method of inspection of every bushel 
of seed. It is your only protection. 
Certification standards must be rigid and properly authorized from ac¬ 
credited sources. With Holmes’ Certified Seed Potatoes this service 
is supplied under the auspices of the State Colleges. Growers must 
faithfully follow the rules or they are disqualified. 
Potato hills spaced 9 to 12 inches apart in the row gave higher yields 
of marketable sized potatoes than either wider or closer spacing, ac¬ 
cording to tests at the Ohio Agricultural Experiment Station. 
Two-ounce pieces gave higher yields than one-ounce pieces, but more 
seed potatoes are required, so this about equalizes matters as to total 
yields of an acre. Thus, the recommendation is to use the smaller 
pieces at the spacing indicated. This will require from 18 to 26 
bushels of seed per acre. 
IRISH COBBLER (Pedigreed Stock). The best early selling sort. It 
is the standard white Potato, and is increasing in popularity yearly 
among the best Potato growers. The tubers are uniformly smooth, 
round and plump; eyes strong and well developed. The flesh is white 
and of excellent quality. Write for prices.

RURAL RUSSETS. (Certified). This is the famous Michigan Russet 
Potato that has probably made more money for the farmer than any 
other variety. The tubers are round to oblong in shape, of good size, 
with pure white flesh. The skin is russet, the eyes few and shallow. 
Our Russets are grown in Michigan from pure State Inspected Certi¬ 
fied Seed, absolutely free from scab and diseases. Ohio uses 125,000 
bushels, two-thirds of which comes from Michigan. A yield of 400 
bushels per acre is not uncommon for Russets. Our stock is fine, 
medium sized tubers. Write for Price List.

nothing to compare with the Early Ohio. Round to oblong in shape, 
pink skin, white flesh of most excellent quality and extra early. Write 
for our Price List.

shape, reddish color with shallow eye. Write for our Price List.

Cobbler except that it matures 2 to 3 weeks later, and, consequently, 
yields better. It is recommended for trial. Write for prices.
