the cheapest pig trough, is made by taking a log about 

 fifteen inches in diameter, and, with an axe and adze, 

 hewing out the inside. For out-door feeding, they are 

 the most convenient troughs we are acquainted with, as 

 they are not easily upset. 



When used for pigs confined to pens, the log should be 

 hewn out in two divisions, one for food, and the other for 

 water, as shown in fig. 46. A twelve-foot log will give 

 about six feet of trough for food, and two and a half to 

 three feet for water. 



A better and equally simple pig trough is made ffom 

 two-inch pine or hemlock planks. The planks should be 

 from nine to fifteen inches wide, according to the size of

 nailed firmly together at right angles, with twenty- 

 penny nails, put nine inches apart. There should be 

 either two troughs for each pen, or the one trougli should 

 be divided into two compartments, one for water, and the 

 other for food. The ends of the plank must be sawed off 

 square and true, and a piece of plank nailed at each end, 

 sufficiently tight to hold water. Such a trough is much 

 more likely to leak at the ends than at the bottom, and 

 great care should be taken to saw them off square, and 

 nail them on tight. When both planks are the same 

 width, the plank that is to be against the side of the pen, 

 and farthest from the pigs should, in nailing, be placed on 

 the other. This will make that side of the trough two 

 inches higher than the one next the pigs, and they will
