SECTION V. 

 BUILDING CONSTRUCTION. 



This book is written for veterinary students and those whose calling 

 will involve the inspection of and reporting upon animal habita- 

 tions. Work of this nature demands a general knowledge of 

 building materials and their uses, the construction of dairy 

 farms and agricultural buildings, and the ability to interpret 

 the plans and other drawings of existing or proposed buildings; 

 therefore the information given in this section will help the 

 reader to acquire the knowledge necessary to make such reports, 

 prepare or criticise plans, and supervise the construction of 

 buildings. 



DRAUGHTSMANSHIP. 



THE following hints should enable one to prepare drawings with 

 that crispness and neatness which carries a feeling of conviction 

 and accuracy with them. 



The first essential is a proper drawing-desk of the correct height, 

 higher at the back than at the front, with plenty of space on which 

 to lay plans, books, instruments, colours, inks, &c. The drawing- 

 desk may be made of whitewood with dressed frame and legs, and 

 a sloping top made of grooved and tongued flooring or thick lining. 

 It should be fitted with two drawers, one for drawings and another 

 for drawing materials. The size of the office available and the 

 requirements of the user will decide the size of the desk, but one 

 about 8 feet long, 3 feet 3 inches wide on top, and 3 feet 3 inches 

 high at the front is a most convenient and useful size. A desk of 

 the foregoing width should be 3 feet 8 inches high at the back. 

 The user must face the light, a good position for his desk being 

 across a window. 



A good yellow pine drawing-board is necessary, and much pre- 

 ferable to the ordinary thin, cheap type of butternut board, which 

 invariably twists and warps. The finest drawing-board is that 

 with a grooved back and heavy back bars fixed with screws in
