Varieties of Blackberries and Dewberries 225 



Luther. Sent out by R. D. Luther, Fredonia, N. Y. Said to be 

 vigorous, hardy and promising. 



Mammoth. This is one of the seedlings grown by Judge J. H. Logan, 

 and thought by him to be a cross between the western dewberry, 

 Rubus vitifolius, and the Texas blackberry. It appears to be similar 

 to the loganberry in type and habit of growth, propagating by tips 

 like other dewberries. Apparently it is similar to the loganberry 

 except in color. The berries are black, very large, often reaching 

 two inches or more in length and very sour. It is not hardy hi the 

 eastern states but is grown extensively in the Pacific Northwest. 

 The canes are peculiar, being covered with small, short spines. They 

 start very early in the season, growing thick and stout until about 

 five feet high, then begin to trail, growing 25 to 30 feet in the season, 

 rooting at the tips in autumn. The leaves are partially evergreen 

 in California. 



Mammoth (D). Two varieties of the eastern dewberry appear to 

 have been sold under this name. Cornell Univ. Exp. Sta. Bull. 

 34 : 306. 



Mammoth (Thompson's Early Mammoth) (H). Said to be like 

 Wilson in size and general habit of growth, but a few days earlier. 



Manatee (D). Introduced by Reasoner Brothers, Oneco, Fla., in 

 1889, as a selected strain of Rubus trivialis. Productive in that state, 

 ripening its fruit in April, and being a good shipper. Also said to 

 succeed in California. 



Mason Mountain. Introduced by R. O. Thompson, of Nebraska, 

 about 1865. Fruit large, resembling Lawton. 



Maxwell. Introduced by A. C. Maxwell, Chanute, Kansas. 

 Described as large, sweet, rich and melting. Lacks vigor, hardiness 

 and productiveness in some localities. 



Mayes (Mayes Hybrid, Austin's Improved) (D). Found growing 

 wild in Texas, on the farm of John Mayes, some time about 1880. 

 Mr. Mayes began cultivating the variety, and found it to improve 

 under cultivation. Later it was sent out by J. W. Austin, of Pilot 

 Point, Texas, as Austin's Improved. The plant is trailing in habit 

 when young, but is said to become stronger and somewhat upright 

 with age. It propagates by tips or root-cuttings. The fruit is very 

 large, of fine appearance, and the plants are prolific.
