The largest number of samples have a content of ash ranging from 
0.80 to 1.10 per cent, and nearly 88 per cent of the samples range 
from 0.77 to 1.20 per cent. The lowest ash content found in this 
examination, 0.76 per cent, was obtained in a sample from Ohio and 
i. one from Canada. In some of the experimental work, however, 
ash contents as low as 0.72 per cent were found. These total ash 
figures may be considered abnormal, as they were found in sirup the 
lead number, malic acid value, and insoluble ash content of which 
were far above the minimum figures.

The same percentage (88.4) of samples in both kinds of sirup have 
ash contents up to 1.20 per cent, although 36 per cent of the sugar 
samples and 26 percent of the sap sirups have an ash content between 
0.77 and 0.89 per cent. The appearance of the ash was not regular, a 
few samples being very green, while many were white or light gray. 
The appearance of the ash depends upon the method of burning.
