DIBBLE’S IMPROVED GREEN MOUNTAIN 
In the Improved Green Mountain we have a better 
Potato than was the old Green Mountain at its best, a 
score of years ago. The tubers are uniform in shape, 
oblong, with two good ends, slightly flattened, creamy 
white skin absolutely free from disease in any form, 
and with pure white flesh of excellent quality. They 
are particularly well adapted to northern latitudes where 
the rainfall is abundant and the temperature is not 
excessively high. As a rule, they do not succeed as well 
in localities where they are subjected to unfavorable 
conditions of growth during the time they are forming 
tubers, as do the members of the Rural group. 
PIONEER RURAL 
The Pioneer Rural was originated by 
Fred S. HoIIenback of TuIIy, N. Y., and 
is a sport of the Russet. It combines 
the yield and drought-resistance of the 
Russet with the white color and sales 
value of the well-known Carman or 
other smooth Rurals. You should try 
a few of this variety. We believe they 
will outyield any smooth Rural you 
have ever grown. 
SIR WALTER RALEIGH 
The last of the Carman creations and 
introduced by Peter Henderson & Co. 
some thirty.years ago. The Sir Walter 
Raleigh is similar to the other two but 
has, in our opinion, the most desirable 
quality of setting more tubers per hill 
and smaller in size, no large or over¬ 
grown tubers at all, but of desirable 
size and shape to command the top 
price in the best markets. 
KATAHDIN 
CARMAN No. 3 
Also originated by Mr. Carman and introduced by him 
several years later, as an improvement over the No. 2, 
which it resembles in every respect, except that it sets more 
heavily in the hill, averaging, with us, three to five tubers 
per hill and mostly merchantable. 
HEAVYWEIGHT 
A selection of the smooth Rural type with characteristics 
similar to Sir Walter Raleigh, except that tubers are in¬ 
clined more to the round form. 
1 he Katahdm was originated from a 
seed ball by the U. S. Department of 
Agriculture at its experimental station 
at Presque Isle, Maine. 
After it had proved its worth as a new 
variety, it was released to the public. 
It is a handsome shallow-eyed, glossy, 
white-skinned variety which matures a 
little later than Green Mountain, but 
earlier than the Rurals. It has very 
few tubers of unmarketable size and 
has all varieties beaten in uniformity of 
shape, size, and in 
general appearance. 
It does well on light, 
friable soil, but is 
not adapted to heavy 
soil subject to 
drought conditions.

Standard 
White Potatoes 
The first five varieties following are 
of the well-known Carman or smooth Rural family, 
the best-known type of 
market Potato now in cultivation 
RURAL NEW YORKER No. 2 
The first of the late Mr. Carman’s introductions that 
proved to be of great value. The Rural New Yorker No. 2 
is a late variety, growing vines dark green in color, upright 
in habit of growth, with purple blossoms. The tubers are 
round to oblong, unusually large in size, white in color, 
eyes near the surface, and it sets, as a rule, only two to four 
tubers per plant or hill, but usually all large ones.
