340 LUTHER BURBANK 



The blueberry and huckleberry are generally 

 thought to be extremely difficult to raise from 

 seed. But if kept sufficiently moist in a peaty 

 soil this may be readily accomplished. 



Cranberry seedlings can be grown by washing 

 out the seeds and sowing in a protected place or 

 in damp sphagnum moss. 



The young seedlings can be transplanted like 

 other fruiting plants, but the operation is rather 

 delicate as with all other Vacciniums. The soil 

 must always be virgin soil, and with hardly a 

 trace of lime, as all Vacciniums prefer what is 

 commonly called an acid soil. 



The cranberry, like most other members of 

 the tribe, spreads by sending out runners. It 

 can be propagated by cutting the vines into 

 small pieces. The plant does not thrive in Cal- 

 ifornia except in some bogs of the northwestern, 

 part of the State. In regions to which it is 

 adapted, however, the cranberry is a crop of con- 

 siderable importance, and there appears to be an 

 unusually good opportunity for some one to con- 

 duct experiments for the development of better 

 varieties. 



Mere selection from the existing varieties 

 would probably accomplish much. And of course 

 still further progress could be expected if the 

 different varieties were hybridized. By such
