Special Methods of Culture 255 



Bush Alpines, which make no runners, are propagated 

 by seedage, but can be multiplied easily by division. 

 These varieties make a large stool, often with thirty to 

 sixty crowns. As each crown is formed it begins to bear ; 

 hence there is a succession of fruit. The crowns, or 

 fingers, may be separated at the end of a season, each 

 with roots attached, and used to set a new bed. The 

 common varieties are Red and White Alpine and Red and 

 White Bush Alpine. Some of the best improved varieties 

 are the Berger, Sutton, Janus, Quatre Saisone, Large Red, 

 Improved White and Belle de Meaux. There is little 

 interest in the Alpines now except among amateurs. 



FALL CROPS AND DOUBLE-CBOPPERS 



Occasionally there are seasons when some varieties of 

 the spring-bearing class bear a fall crop. This phenome- 

 non usually follows a midsummer drought, which checks 

 growth so severely as to approximate the normal winter 

 resting period ; then rains come and quicken the plants 

 into the vigorous growth and fruitfulness of a second 

 spring. Fall crops were especially common from Maine 

 to Missouri in 1903; in some places as much as half a 

 crop was gathered in October. The Cumberland Triumph 

 was noted for producing fall crops. 



In those parts of the Pacific Northwest and the moun- 

 tain states where irrigation is practiced, "double-cropper" 

 varieties are common. These are sorts that under certain 

 conditions produce two crops a year, one in the spring, 

 the other in the fall. Any variety that has many crowns 

 and runners will succeed as a double-cropper in that 

 region. Those most commonly used are : Jessie, Clyde, 

 Excelsior, Magoon and Warfield. Double-cropping is the
