PIBBLE'S 
CERTIFIED liiJ SELECTED 
SEED POTATOES 
Northern-grown from selected certified stock 
seed, planted on soils especially adapted to each 
variety, producing a quality that for vigor, purity, 
and productiveness is unexcelled. 
For nearly a half century the sales of Dibble’s Seed 
Potatoes have gradually increased until the annual 
sales reached and passed 100,000 bushels. We do 
not have a single salesman on the road, every order 
coming to us through the mail, and at least four- 
fifths of our business from old customers, thousands 
of whom plant Dibble’s Seed Potatoes annually. 
This is the best tribute to the quality of our Seed 
Potatoes. Merit wans. 
We grow on our own farms, and in this section, 
varieties of Potatoes adapted to our soils, and as to 
the earlies, w^e have them grown for us on contract 
in the virgin soils of regions still farther north, 
where these early types grow larger and better 
tubers than can be obtained on the old lands of the 
eastern states. 
Seed Potatoes that are northern-grown, moved 
south only from 100 to 300 miles, frequently produce 
double the crop of home-grown seed, even of the 
same variety. 
We can furnish State Certified Seed Potatoes, or 
Selected Seed Potatoes, grown from Certified seed. 
We Are Headquarters for Seed Potatoes 
We offer a jew varieties, early, intermediate, and late, that 
have been proved “Best by Test.” This list was approved by 
Dr. William Stuart, of the United States Department of Agri¬ 
culture, whom we consider the greatest authority on Potatoes. 
We have good crops of all varieties this year, both early and 
late, and can take care of your requirements, whether you need 
a bushel or a carload.
