104 SWINE GEOKGE E. DAY. 



Plan of Piggery. 



The plan which is given here is taken from a piggery on 

 the farm of Mr. J. E. Brethour, Burford, Ontario. Its 

 construction is comparatively cheap, and it possesses many 

 desirable features. It is capable of many modifications, and 

 a careful study of the plan will be helpful to those who 

 intend to build. Of course, the building can be made any 

 length desired. 



The building is 36 by 100 feet, outside measurement. A 

 cement wall, 8 inches thick, rises three feet above the floor. 

 On top of this wall the frame is built. The walls are built 

 of two-by-four inch studding, boarded on the outside with 

 cheap lumber, covered with building paper, and tightly clap 

 boarded on the top of the paper. On the inside the walls 

 are lined with matched lumber so as to form a dead air space 

 inside the wall. The lining also extends over the lower side 

 of the rafters, giving a dead air space to the roof as well as 

 the walls. 



From the cross section, it will be seen that the total height 

 of the wall on the north side is 11 feet, and of that on the 

 south side 8 feet. The roof has the same pitch on both 

 sides, so that there is a drop of three feet from one section 

 of the roof to the other at the center of the building. In this 

 space windows are inserted, to throw light, and a certain 

 amount of sunshine, into the row of pens along the north 

 side of the building. These windows are hinged at the bot- 

 tom and can be opened at any angle, according to the re- 

 quirements of ventilation. A ratchet device, similar to that 

 used for opening the ventilators in greenhouses, would be 

 very convenient for this purpose. 



The floor is cement. Cement is so durable and so easily 

 cleaned that it seems to be about the only satisfactory floor. 

 The part A B (see cross-section) is six inches higher than 

 C D. There is a fall of one and one-half inches from A 

 towards B, and a fall of three inches from D towards C. 

 Thus all the drainage is towards C, the lowest point, and the
