square, structures the sides of a double-pitch roof may face 

 either north and south or east and west. In houses with two or 

 more compartments a double-pitch roof must, as a rule, face north 

 and south ; in single- 

 compartment houses the 

 tent-roof type of con- 

 struction may be used (or 

 approached), with sides 

 very low and the slopes 

 of the roof facing east 

 and west. Shed or single- 

 pitch roofs on single- 

 compartment houses may 

 pitch in any direction desired ; on houses with two or more com- 

 partments they must, as a rule, pitch either north or south, and 

 preferably south, because

Double-pitch roofs with 

 unequal sides are some- 

 times made to adapt the roof to other features of construction. 

 Thus in some brooder houses with sunken walks in the rear, the 

 roof has a long pitch to the south, 

 over the pens, and a short pitch 

 to the north, over the walk. In 

 some of the open-front plans of 

 houses, too, the front slope of the 

 roof is longer than the other, and 

 sometimes at a different angle. In 

 what is known as the semimonitor- 

 top style of construction the part 



of the house under the front slope is several feet lower than that 

 under the rear slope of the roof, to allow placing windows in the
