troduction from Samuel Cooper, Delovau, New ^'ork. Il is very 

 similar in plant and fruit to the wcIMxiiown Supei'l), hut the 

 herries are larj^^'r in size, of hetter (lualily, and the plants are 

 more produetive. The variety is adapted to conditions under 

 which the older vai'iety thrives. Under most conditions Peer- 

 less is a better strawberry than Superb and should replace it 

 in most strawberry repfions. 



767. Progressive. — Of the score or more everbearing straw- 

 berries introduced in recent years, Progressive is the most widely 

 known. Its outstanding characters are hardiness, freedom from 

 disease, and handsome well-flavored fruits. The plants pro- 

 duce in the spring as well as the fall. The variety is adapted 

 only to northern climates. Progressive originated with Harlow 

 Rockhill, Conrad, Iowa, in 1908.

 smooth; season of bloom early; fruit-stems variable in length, thick, much 

 branched; calyx flat, reflexed, attractive green and often with pink tinge.

 small, blunt -wedge to blunt -conic, glossy, medium to dark red, colors evenly;

 quality; seeds prominent, raised. 



768. Prolific (Fig. 301). — This variety originated on the 

 grounds of the New York Agricultural Experiment Station and 



w^as distributed in 1908. Because of the vigor 

 and productiveness of its plants, and the at- 

 tractiveness of its large, handsome, well-fla- 

 vored berries, the varietj^ gives promise of 

 taking high rank as a commercial sort. Un- 

 fortunately, the plants are somewhat suscep- 

 tible to leaf-spot. 



Perfect. Plants very numerous, vigorous, unusually 

 productive, yielding on the Station grounds as high 

 as 14,502 quarts to the acre; foliage somewhat sus- 

 ceptible to leaf -blight in unfavorable seasons; leaf-
