There is also a door, N, opening to the alley on the in- 

 side. This door is hung so that when it is open it will 

 turn the pigs toward the front end of the house where 

 they are to l^e weighed. It also permits of changing pigs 

 from any one pen to any other pen, and easy access for 

 the attendant. L represents the trough, which is placed 

 on the side of the pen next to the alley and which with 

 the arrangement of a swinging panel above this trough, 

 as is shown in the illustration at the first of this chap-

 The fender in the pen is shown by K in the plan. This 

 consists of a two-inch tubular iron bar, placed on iron 

 jwsts of the same dimension, and set in concrete in the 

 floor. This bar is placed eight or nine inches above the 

 floor and about six inches from the wall, and is to pre- 

 vent the sows crushing the pigs at farrowing time. Ilie 

 sow will necessarily make her bed in this corner, as the 

 other three corners are occupied, two of which ha\e 

 doors and the other the feed trough. 



"D in the plan shows the platform scale on which the 

 pigs are weighed as desired. This scale is fitted with a 

 frame, and the door on the side next to the alley, shown 

 at O, opens so that when the pigs come down the alley, it 

 will facilitate turning them upon the scales. At the other 

 end of the scale platform is a smaller door in the frame 

 which opens through a door, P, of the building, thus al- 

 lowing the pigs to pass from the scale room directly to 

 the outside, where there may be a loading chute leading 

 to a wagon. 



"F is the feed-mixing room in which are bins for 

 feeds of various kinds represented by I. There is also a
