| These weights vary slightly for different fruits, and in commercial packing the fill 
is not quite as strong as in these experiments. The figures, however, will furnish a 
fairly close guide as to the quantity of sugar required in canning. They also point 
to a cause of some of the difficulties in correct labeling under the new net-weight law.
