118 BOARD OF AGRICULTURE. [Pub. Doc. 



midnight is not nearly so great as in a stable running east 

 and west. With a large number of windows on the east and 

 west sides, and but few on the south end, in the early morn- 

 ino; and the afternoon the sunlio:ht streams through the win- 

 dows in the sides, whereas little enters during the middle of 

 the day, when the temperature of the stable is naturally 

 highest. 



Where stables run east and west, and the animals are 

 arranged in two rows facing a central passageway, those 

 animals upon the south side get the benefits of all the sun- 

 light, while those on the north side get none. 



In combination barns, used for storage and stable, where 

 the cattle are kept under the scaffold, it is better, without 

 question, to give them the southern exposure rather than the 

 northern, for the objections to the wide range of temperature 

 do not offset the stimulating effect derived from direct sun- 

 light upon the animals, or the disinfecting action it has in the 

 stable. 



To secure effective ventilation in any building, two sets 

 of openings are necessary, namely, inlets for the admission 

 of pure air, and outlets for the escape of impure air. This 

 applies to both systems of ventilation, but the relative 

 position of inlets to outlets is not the same in both. 



When the artificial system is employed, especially where 

 heated air is the motive force, the inlets should be located in 

 the walls near the ceilings, the outlets in the floor, on the 

 same side of the room as the inlet. 



In connection with this subject, I desire to call your 

 attention to the experiments of Mr. Briggs of Connecticut, 

 the results of which appeared in the report of the Connecti- 

 cut State Board of Health a few years since. In natural 

 ventilation, where cold air is brought in, the inlets should be 

 in the walls near the floor line, the outlets in the ceilings, 

 roofs or walls above. 



In the storage of excrement about stables, every pre- 

 caution should be taken to guard against contamination of 

 the air of the stable or the air introduced into it to take the 

 place of the foul air removed. Water-tight manure pits or 

 sheds for the storage of excrement, situated at the end of the 

 stable, are both convenient and sanitary.
