Part II. application of the principles in locating, laying out, 



AND constructing POULTRY HOUSES 



Laying out the foundation 



The location of the house having been decided, find the desired height 

 of the floor and represent this level by X. This level should be at least 

 5" above the highest point on which the house will be built, except on 

 very uneven land, when it may be advisable to excavate, grade, and build 

 part of the floor below the original ground level. Locate a corner of

the proposed building, and about this corner drive three stakes, as a^b-c 

 in Fig. 55, which are approximately 3 feet apart. On each of these stakes 

 find the level of X and connect these points by boards, as represented by 

 ab and be. 



The level of the floor can be determined either by the use of the transit, 

 which is best for accurately laying out large buildings, or with a spirit 

 level and straight-edge, which are equally efficient in laying out small 

 houses. When using the level and straight-edge, drive a stake at a cen- 

 trally located spot and saw off this stake at the level X (the level of the 

 floor). Then with spirit level and one end of the straight-edge on this 

 stake it is easy to obtain the level X on the corner stakes. When the
