Seed Potatoes 
During recent years, the attention of potato growers has been directed to the fact that the 
yield may be greatly increased by the use for seed purposes of immature tubers. That is, tubers 
from a crop that developed late in the season and still unripe when cut down by the frost or from 
northern districts where the shorter and cooler season does not admit of the crop ripening. The 
importance of using such seed has been demonstrated by our Experimental Stations as well as by 
private growers, the increase in yield often being from 25 per cent, to 50 per cent, over ordinary 
seed. 
We grow our seed potatoes on the "Immature" principle making our planting late in the 
season and thorough spraying and cultivation promotes a vigorous, healthy plant growth and. in this 
way produce seed stock that will give the very best results. We aim to have our stock rather 
under than over the ordinary size as such stock plants to better advantage. 
■! 
It is advisable to treat all seed before planting by immersing seed for 2 to 3 hours in a 
solution of Formaldehyde in the proportion of 1 pint to 30 gallons of water. It pays.

ROCHESTER ROSE— Fii 
BLISS TRIUMPH— Earliest of the earlies. 
A round, red variety, which matures at least 
two weeks ahead of Cobbler or Eureka. Of 
good quality and especially valuable for its 
extra earliness. 
PERFECTION— This is our choice of the long 
white type. Tubers very smooth and of the 
highest quality. A vigorous grower and re- 
markable heavy yielder. 
ROCHESTER ROSE— One of the most pro- 
ductive and surest cropping potatoes we have 
ever grown and certainly the best of the "Rose" 
type. Tubers large, uniform and symetrical 
and of first class cooking quality. A variety 
of great value for home use or local market. 
Medium early. 
Wanted 
Kindly forward as quickly as possible 1000 
24 Herbert Raspberry. The other lot reached me C 
Yours t 
s and very productive. 
GREEN MOUNTAIN— Adopted as the stan- 
dard round, white type potato by the Depart- 
ment of Agriculture. A first class variety in 
every respect, 1 lb., 15 cents; 5 lb, 40 cents; 
10 lb., 70 cents; 1 pk., 90 cents. 
UP-TO-DATE— This great potato of the 
round or kidney shaped white type is by far 
the best of its class we have ever grown, sur- 
passing them all in vigor of top growth, free- 
dom from disease,, productiveness and keeping 
and cooking qualities. As a shipper it is scarcely 
equaled by any other variety on account of its 
tough skin. Being the leading potato in the 
British Isles we consider it worthy of first place 
in Ontario as well. Start growing "Up-To-Date."
