The foregoing experiments Were made with Muscat grapes, and examinations of the 
commercial pack from these sources gave similar results. 
LOGANBERRIES. 
The loganberry is the result of an accidental cross of a wild blackberry and a rasp- | 
berry, made by Mr. J. H. Logan at Santa Cruz, Cal., in 1881. It is grown in a very | 
limited way in various parts of the United States, but for canning purposes only on the © 
Pacific coast. It resembles a large blackberry in size, is red in color, and hasa distince- § 
tive flavor of both the blackberry and the raspberry. Itis grown and harvested in the 
same manner asthe blackberry. Itis one of the fruits that most persons find improved | 
by cooking. It is very acid and needs a heavy sirup. Because of the limited supply | 
and the difficulty of keeping them in the ordinary can, only a few are packed. They | 
bleach badly and cause pin holes, with resultant spoilage. The best results are 
obtained with inside-laquered cans, but even these will not keep them in good condi- | 
tion for more than a few months.
