SELECTION AND PREPARATION OF STOCK.

The tomatoes should be home-grown, of a red variety having the minimum

of yellow and purple color, be picked when ripe, and delivered to

the factory promptly without mashing. All tomatoes should pass over

an inspection table, the rotten and otherwise unfit fruit should be

discarded, and the green tomatoes should be returned to crates to

ripen. The stems should be removed when the best color is desired,

and the tomatoes should be thoroughly washed to remove dirt and mold.

Dumping a crate of tomatoes into a hopper of dirty water and playing a

gentle spray of water on part of them merely wets the skin and makes

them appear bright.
