numerous, usually deeply colored. Skin much deeper pink than that of the Early | 
Rose. Sprouts short, stubby, and showing about as much color as those in section 2. 
The varieties now thought to belong to section 3 follow. 
Crine’s Lightning. New Ideal (PI. VIII). 
Extra Early Red Rose. New Scotch Rose. 
Jones Pink-Eyed Seedling. Old Early Rose (P1. VID). 
Lee’s Favorite. ~| Seneca Beauty. -

5.—-EARLY OHIO GROUP. 
This group is relatively more important than that of the Rose, 
owing to the fact that the Early Ohio variety is much more exten- 
sively grown. In the potato-growing regions of the Middle West 
the Early Ohio is still one of the leading commercial varieties. This 
is particularly true in the Red River Valley of Minnesota and North 
Dakota and in the valley of the Kansas (Kaw) River; it is equally 
true in other less well-known localities. While in many respects the 
varieties in this group are very similar to those of the Rose group, 
there are certain distinguishing characters which make their recog- 
nition comparatively easy. Plate IX, Hen 2, and Plate X show 
different views of the Early Ohio. 
Description.—Vines very similar to those of the Early Rose in habit of growth, 
character of foliage, and color of flowers; they mature a little earlier, however. Flowers 
white. Tubers round-oblong with full, rounded seed and stem ends (Pl. X). Eyes 
numerous, rather shallow, but strong, sometimes protuberant. Skin or flesh light 
pink, except in the case of the White Ohio, with deeper color around the eyes, par- 
ticularly around the bud-eye cluster. Surface of skin more or less numerously dotted 
with small corky dots (lenticels). (Pl. X, tuber 157.) These dots either do not occur 
at all or are relatively inconspicuous on the Rose varieties. Sprouts short, much 
enlarged at the base (PI. IX, fig. 2), color varying from carmine-violet to violet-lilac 
or magenta-lilac. 
Apparently most of the varietal members of this group are simply 
renamed Early Ohios; at least this statement is true of the first four 
varieties in the following list: 
Karly Ohio (PI. X). | Early Acme. 
Early Market. | Early Six Weeks. 
Prize Early Dakota (Pl. X). Late Ohio. 
Ratekin’s Red River Special. White Ohio. 
6.—HEBRON GROUP. 
The varieties in the Hebron group are chiefly distinguished | 
from those in the Rose group by the color of their tubers. Most 
of them are early-maturing varieties. The Early and Late Beauties 
of Hebron were rather extensively grown.a quarter of a century or 
more ago, but are now seldom grown commercially. Their decadence 
has been largely due to the fact that they are very susceptible to the 
late-bight. Another factor which may have had some influence in 
this direction is the shape of the tuber, which is undesirably long.
