II. GRAPES OF THE SOUTHERN STATES 
The grapes of the Southern States, as previously noted, are derived 
chiefly from the species known as Vitis rotmidifolia or its varieties. 
Through the courtesy of Dr. J. S. Caldwell we were provided with samples 
of so-called Muscadine grape juice which had been prepared by Charles 
Dealing and Guy F. Yerkes, of Willard, N. C. These samples were 
designated by the following popular names of the particular varieties 
of grape: (1) Thomas, (2) Scuppemong, (3) Latham, (4) Mish. All the 
juices were cold-pressed and were clear, pale yellow or brownish yellow 
liquids. They had a sweetish, honeylike odor, quite unlike that of 
the northern grape juices. The test for methyl anthranilate, which was 
conducted with 500 cc. of the respective samples, gave in all cases a 
perfectly negative result. 
III. CALIFORNIA GRAPES 
The grapes of California may be considered as representative of the 
European species, Vitis vinifera , of which a very large number of varieties 
have been produced through cultivation. Two samples of juice from 
grapes of the 1921 crop were kindly supplied by Prof. W. V. Cruess,
