38 BULLETIN 196, U. S. DEPARTMENT OF AGRICULTURE. 
Experimental lots of fruit were canned, using 400, 450, 500, 540, 560, and 600 grams | 
in water. The weight of the fruit on the cut-out for the corresponding lots was 405, 
445, 510, 530, 550, and 580 grams, there being very little change. The fill from using 
only 400 and 450 grams was clearly short weight; the use of 500 grams gave a slightly 
slack fill; and with 600 grams the can was somewhat too full. To use 540 and 560 
grams required tapping of some cans, in order to get the fruit in, but, on the whole, 
they were easily filled. On the cut-out they lacked only a little more than one-half 
inch of being full after draining. 
Experiments were made in canning cherries with sirups varying from i0° to 60° 
The cherries were divided into three lots: Small, or those passing through a No. 26_ 
sieve; large, those remaining above a No. 30 sieve; and a medium size which were 
pitted. For comparative purposes, the average of the examinations of the commer- | 
cially canned article has been added to the table. The four grades which were 
available were extra (30° sirup), extra standard (20° sirup), standard (10° sirup), and 
seconds (water). 
The waste consists of stems and pits. The loss in canning cherries with pits varies 
from about 15 to 18 per cent, and, when pitted, from 25 to 35 per cent. The loss 
with small cherries is much greater than with large ones, as the pits do not vary as 
much asthe pulp. The cherry stems and pits are dried and used for flavoring in cough | 
sirups, etc. 
Effect of canning cherries in sirups of different degrees. (Royal Anne; weight of fruit | 
used, 500 grams in No. 23 can.)
