CHEMICAL COMPOSITION OF AMERICAN GRAPES, 3 
samples was made and analyzed. Analyses of 34 individual samples 
were also made. 
The samples taken in North Carolina were selected in the vine- 
yards by J. H. Jeffries, supermtendent of the Pender Experiment 
Farm, which is owned and operated by the North Carolina State Board 
of Agriculture. Mr. Jeffries kindly undertook this work and sent the 
samples to Raleigh, where they were analyzed. Dr. B. W. Kilgore, 
chief chemist for the State Board of Agriculture at Raleigh, fur- 
nished laboratory room, apparatus, etc., and gave every assistance 
possible. 
CHEMICAL COMPOSITION OF GRAPES EXAMINED. 
The data represented in Tables 1 and 2 are arranged by localities, 
and the average, Maximum, and minimum results are given when 
- more than one sample was taken for each locality; a total average of 
all the analyses of each variety is given with maximum and minimum 
results as to solids, sugar, and acid on all the samples of any given 
variety examined. The specific gravity determined by a pycnometer 
at 15.6° C. is given individually for all single samples and the aver- 
age is given where two or more samples are recorded for any locality. 
The determinations as to composition are given in grams in 100 cc 
of expressed juice.
