The Western Dewberries 131 



while others are disgusted with it. Much of this diversity 

 of opinion, and much of the failure to secure good results 

 is, without doubt, due to the mixed and inferior character 

 of many of the plants which have been sold. Even where 

 they succeed, they have not been grown very extensively, 

 as a rule, and any reliable estimate of an average yield 

 can hardly be formed. 



PROBABLE PROFITS 



With the question of yield so much in doubt, the ques- 

 tion of profit must also be unsettled. It may be said, 

 however, that those who succeed in obtaining a good yield 

 nearly always find them profitable, owing to their season 

 of ripening and consequent high price. 



THE WESTERN DEWBERRIES 



On the Pacific Coast, varieties of the dewberry class 

 have attained great commercial importance. The Ever- 

 green blackberry (see page 117), owing to its habit of 

 growth may be readily classed among the dewberries. But 

 the loganberry and the Mammoth, seedlings of the native 

 western dewberry (Rubus vitifolius), have become most 

 prominent. Both of these varieties were originated by 

 Judge J. H. Logan of Santa Cruz, California, from seeds 

 of the western dewberry taken from plants growing beside 

 an old variety of red raspberry and the Texas Early black- 

 berry. This blackberry is an upright species which in 

 the mild climate of California, possesses the charac- 

 teristics of an evergreen.
