CANNED SALVO. IV TIIE WIRITTOUSE READY FOR DISTRIBUTION
Some of the most important advances man has made in his food supply have been the result of war. Napoleon's bounty brought about the
development of the art of canning foods (see page 1). Before his day not even the scientist in his laboratory could "put up a can of food;
today there is not a rural housewife so uscientific as not to be able to do so. The commercial canneries of the United States alone no produce

It is only a generation since the tomato was first accepted by civilization, and yet today millions of people reward it as an almost indispensable part of the kitchen vegetable supply. New Jersey is our leading tomato and asparagus producing State; New York leads in cabbage, onions, and sweet corn; Florida holds first place in the production of green beans, cucumbers, egg plant and lettuce; California produces more cantaloupes and muskmelons than any other State, and Texas makes its bid for vegetable-producing fame by leading the procession as a producer of watermelons.
