Cyclopedia of farm crops : a popular survey of crops and crop-making methods in the United States and Canada cyclopediaoffarm00bailuoft Year: 1922, c1907 SWEET-POTATO SWEET-POTATO 617 ary to use as posts in the vicinity. The walls may be built of wood by setting posts two or three feel apart and spiking slabs or planks on the out- side. A rough floor is laid over the floor beams, four or five inches of soil is put on, and then the roots and the covering are applied in exactly the same way as with the manure hotbed. A cover may be conveniently constructed by placing raf- ters eight or ten feet apart and connecting them with the ridge-pole, forming a skeleton roof; over this is stretched ordinary unbleached cotton. (Fig. 841.) There is no great necessity for heavy cloth such as tents are made of, except that it will last longer. The cotton cloth should be sewed into a single sheet and a roller made by tacking together strips three-fourths-inch by one-and-three-fourths- inch, fastening the edges of the cloth between them. The gable end may be of boards or of cloth. After the potatoes are bedded the cloth tent is put in place and kept there until the plants begin to push through, which should be in about ten days to two weeks. Sometimes a few precocious sprouts will be through in less than a week. After the plants begin to bi'eak the soil, attention should be given to ventilating the bed on very hot days. A thermometer should be placed at some average point in the bed, and when the outside temperature is in the eighties, as often happens in the latter part of April or May, the cover should be rolled up, and unless the night is unusually warm it should be lowered at sunset. As warm weather and plant- ing time comes on, the cover may be rolled up and the bed kept open to the air the greater part of the time. After the roots are bedded the bed should be moistened by watering. It is a great mistake to bed the roots
