and dryness, but requires a trifle more building material than is neces- 

 sary to build a house of the same size with a " combination roof," or a 

 "gable roof." Observe in Figures 348 and 351 the absence of projec- 

 tion on the north side. This construction enables the paper to be run 

 continuously without break at the eaves, thus making an air-tight joint 

 and preventing rain water from washing the soil and doing away with 

 eave troughs. 



Q. 5. Hoiv many square feet of floor space should he allowed per 

 hen? 



Ans. 5. Page 282, paragraph i. Each pen is intended to accom- 

 modate from thirty to forty fowls each, which allows from four to five

square feet of floor space per hen. Where fowls are more crowded than 

 this, they get the benefit of greater warmth because they heat up the 

 air space more effectively, but suffer because they have less freedom 

 of action and, where proper ventilation is not provided, are likely to 

 suffer the ill effects of a contaminated, stagnant air. The more fowls 

 that are kept in a given space, the more often the pens must be cleaned. 

 The smaller and more active breeds appear to require a little less floor 

 space per hen than do the larger fowls, even though the heavier fowls arc 

 less active, and theoretically would require less freedom of action.
