HOUSES. 53 



Headers to be placed under ventilator. 



Ventilators on side, two by four feet, continuous, and to 

 lap on post one-half. 



Glass ten by fifteen inches, double thick, second quality, 

 lapped and bedded in putty. Glass set fifteen inch 

 way. 



South ends of houses glass, with exception of door, which 

 should be four feet wide so as to admit a wheelbarrow 

 readily. 



North ends of houses opening into shed to be made of 

 tongue and groove pine, with doors the same size 

 as those on south end. 



Walls of shed to be made of rustic siding nailed to two by 

 four studs set eighteen inches apart. Inside of shed 

 to be lined with tongue and groove yellow pine. 



Wall plate of shed, two by six yellow pine. 



Top plate of shed, same as wall plate. 



Doors in north wall of shed, four feet wide, opening 

 opposite doors in north end of houses. 



Posts for sides of beds, two by four hemlock, set four 

 feet apart, and wired to opposite posts or to stakes to 

 prevent spreading. Set wires ten inches below top of 

 bed. 



Sides of beds, one by twelve inch hemlock boards nailed to 

 outside ot the two by four posts. 



Heating pipes, black wrought iron screw joints, two 

 one and one-half inch flows for each house and ten 

 one and one-quarter inch returns (five on each side of 

 house). Pipes run so that the highest point, includ- 

 ing expansion tank, is directly over the boiler. 



Flow and returns in all houses to have the same fall, i. e., 

 about one inch for every ten feet of pipe. 



To feed five houses of the size here given (twelve by one 

 hundred feet), it will be necessary to run out two two 

 and one-half inch pipes from the boiler, allowing one 

 pipe to feed the two houses on the west and one to 

 feed the three on the east. The west is given the ad- 

 vantage on account of the greater exposure. 



Top ventilators operated by plain lifting rods with holes 

 and pins to give a four to sixteen inch opening.
