In the early spring, before the ground is warm enough to make seeds grow, the gardener starts his plants in "hotbeds." These are long wooden boxes, or frames, without bottoms, covered with glass. They are usually placed on the south side of some building or high fence. The glass covers allow the warm sunshine to enter the "beds" freely, but they prevent the rapid escape of the heat. You see now why they are called "hotbeds." They are like small greenhouses. A little later in the spring the fields are thoroughly cultivated and the plants transplanted. Of course only the vegetables desired for the early market are started in this way. What advantage is there in having the vegetables ready for the market very early in the season? Vegetable farming is not easy work, although it is a pleasure to see things grow day by day as you care for them, and as nature supplies her sunshine and her rain. The fields must be cultivated almost constantly, to keep the soil loose, as well as to remove the weeds. Much of the weeding has to be done by hand, which is tedious work. We want our vegetables fresh every morning; and as the truck farms are at some distance from the city, the farmer must load up his wagon the night before. Of course much produce is sent to the cities on trains, but where farmers live near enough to deliver it themselves, their crops are more profitable to them. Why? [Illustration: FIG. 17.--A Market Scene.] Everything is put in readiness before dark; and while others are still in bed, the farmer mounts his wagon to start toward the sleeping city. I have often ridden ten or fifteen miles on such a load before the stars faded away. It is a novel experience. At first the night seems strangely still, but soon you are able to distinguish many voices coming from various places. The frogs croak from the ponds by the roadside; crickets and locusts send their shrill notes from grass and tree; a night owl startles you by his dismal hoot; the lamps of the fireflies gleam, then disappear only to shine out again a little farther on. At last a faint glow appears in the eastern sky, which grows brighter and brighter until the shining face of the sun is pushed above the horizon. Do you not think such a ride would be more enjoyable than a street car ride? In the cities there are market places where produce from the country is taken. In Chicago there is a very busy street where much of the buying and selling is done. Study the picture carefully. Here the buyers from hotels, restaurants, and stores, as well as the men who wish to peddle the produce from house to house, go for their daily supplies. There are also commission merchants whose stores are on this street. They sell the produce for those who ship it to the city by train.
