CERTIFIED 
and 
SELECTED 
SEED POTATOES 
Northern-grown from selected certified stock seed, 
planted on soils especially adapted to each variety, pro¬ 
ducing 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 wins. 
We grow on our own farms, and in this section, varieties of 
Potatoes adapted to our soils, and as to the earlies, we 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 A re 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 Agriculture, 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.
