 be fire-proof, and constructed either of fire- 

 brick covered with a light coat of cement, or of 

 concrete. In the latter case the walls may be 

 hollow or solid. In building stables the hollow 

 construction assures a warm room in winter and 

 a cool one in summer, the air acting as a non- 

 conductor and forming an easy method of in- 

 stalling the King system of ventilation. All 

 floors should be provided with a damp-proof 

 course of hea\'y tar paper between the concrete 

 and the sub-base, or otherwise the cattle and 

 swine may contract rheumatism. 



Carpenters will be needed to build the forms;

 a structure. The concreting may be done by

 an experienced foreman. The finishing can be

 painted, with cement and sand grouting. Out-
