Varieties of Blackberries and Dewberries 223 



about fifty seedlings. One of these, the Loganberry, was very similar 

 in every respect to the parent, but much larger and a stronger grower. 

 At the time the seed was sown Judge Logan did not think it possible 

 to cross the Aughinbaugh with the raspberry, but the characters 

 developed by this seedling led him to think it to be a hybrid between 

 them. Judge Logan states that out of thousands of plants grown 

 from seeds of this variety, not one has ever shown, so far as he is 

 aware, any of the distinct characteristics of either parent, not one 

 has gone back to the original type of either the raspberry or the 

 Aughinbaugh, though most of them are inferior to the original plant. 

 He also states that he has never succeeded in crossing the Loganberry 

 with either of its parents, nor with seedling crosses between the 

 Aughinbaugh and the Texas blackberry. 



In the characters of the plant, and in the shape and conforma- 

 tion of the fruit the variety is essentially like the Aughinbaugh, 

 propagating entirely by tips, though by artificial methods they 

 may be grown from hard-wood cuttings. The core remains with 

 the fruit, like the blackberry, its principal resemblance to the 

 raspberry being in color and flavor, although the dewberry dom- 

 inates in flavor. Judge Logan says: "As to the fact of the plant 

 being a hybrid between the blackberry and the raspberry, of course 

 there is no absolute proof. The color, with the distinct raspberry 

 flavor of the fruit, and the circumstances under which it originated, 

 I think render the fact of such a cross almost certain." The fruit 

 of the loganberry is illustrated in Plate VI. 



The other plants in this lot of seedlings Judge Logan thinks to 

 have been crosses between the Aughinbaugh and the Texas, as he 

 expected, though they resemble the Aughinbaugh in most of their 

 characteristics. 



The hybrid origin of the loganberry has always been open to 

 question, as recognized by Judge Logan himself. Recent observa- 

 tions reported in "The Journal of Heredity" for November, 1916, 

 indicate that the type is not the result of a cross as has been com- 

 monly supposed. W. O. Backhouse, Economic Botanist to the 

 Argentine Government, reports many seedlings grown by himself 

 and others which do not behave as seedlings of hybrids may be 

 expected to behave. This is in harmony with Judge Logan's ex-
