THE POTATO 377 



is an improved type of the old Peachblow, a 

 variety grown in this country for over fifty years, 

 and is one of the oldest varieties in existence. 

 Originally it was yellow fleshed, often hollow and 

 bitter of taste. Peter Henderson, a well-known 

 New York seedsman, developed this variety, and 

 in 1883 some of his Perfect Peachblows were 

 brought to Colorado and planted in the Roaring 

 Fork Valley. The perfected variety was of white 

 flesh, never hollow nor bitter, and proved an ideal 

 potato. It was round and slightly flattened on one 

 side, with few eyes and a tough skin. It became a 

 great favorite and is still the leading variety on the 

 western slope of Colorado. 



Perfect Peachblow, — My first efforts were in 

 the direction of increasing the tonnage yield of 

 this variety. The trouble most found was that 

 the hills produced one or two potatoes of great 

 size and many small ones. The large potatoes 

 often cracked open and the crop as a whole lacked 

 imiformity. My method was first to plant the 

 size of potato I desired to produce and later to 

 select my seed from hills producing not less than 

 twelve potatoes of uniform type and size. By 

 this method I have been able to secure a crop of 

 imiform and fixed type characteristics. This plan 

 resulted in greatly increased production, but sub- 

 sequently I found it advisble to sacrifice some of 

 this increased yield to quality. I have succeeded 

 in producing a uniform type of Perfect Peachblow, 

 of fine quality, fixed type characteristic and fairly 

 uniform size.

 opportunity to see the work being done in type 

 breeding of potatoes on the Earl of Rosebery's 

 Dalmeny Farm in Scotland. Since then I have
