 liouse. It is I20 feet long by 30 feet wide, and is rep- 

 resented in the figure by O, S, T, U. X, Y is the alley

 to be loaded on the wagon directly from the pens and 

 hauled to the fields.

 the alley, shutting off the pigs from the rest of the build- 

 ing, are shown by R. The pens A are ten feet wide and
