THE PIG. 483 



ply steam to such a mass, is to run it through a coil inside, 

 placed on the bottom. The coil is in two parts, running 

 backward and forward from the center each way, three 

 turns of the coil, terminating in a goose-neck at each end 

 of the car, which goose-neck comes above the water and de- 

 scends within four inches of the bottom. This effectually 

 prevents the pipe from filling with water or mush ; and the 

 steam, in passing around this coil, keeps it very hot, and, 

 discharging near the bottom, keeps all the heat in. To as- 

 sist in keeping the heat in, a folding cover may be used, 

 which is spread out in a moment, and removed as soon. 

 When mixed, it is allowed to cook for an hour and a half. 

 It requires no stirring, as in boiling over a fire. These cars 

 are lined with No. 22 sheet-iron, riveted and soldered, which 

 prevents any break or swelling of the wood-work of the car. 

 This lining is rubbed over occasionally with tallow, which 

 prevents rusting, and the mush from sticking to it, or, bet- 

 ter still, if the lining of the car is made of galvanized iron, 

 which will not rust for a long time. 



In the center of the feeding floor should be placed a pair 

 of eight-ton platform scales, for the purpose of weighing 

 any pen of hogs at will. A movable railing placed across 

 the floor at each end of the scales, with a small gate in one 

 to let the hogs in, and the hogs from any pen may be driven 

 upon the scales in two minutes, without disturbing the 

 rest. 



This is a general sketch of the swine-house proper. The 

 corn-cribs and the engine-house will be at one end, and may 

 be made as roomy and convenient as the feeder chooses. 

 The breeding-pens may be added to the end opposite the 

 corn-cribs and engine-house ; but this same feeding floor 

 should run through all, so that the car can reach every pen. 

 It is intended that there shall be no freezing in this house ; 

 and, with the use of the engine, water is easily pumped into 

 an elevated reservoir, from which it may be run to any part
