FENCES AND FARM BUILDINGS Ql 



sents the mill with its sails "out of the wind." To set the mill 

 running, they are drawn up, as shown in Fig. 13, and held in posi- 

 tion by a weighted lever which yields to the action of too violent 

 winds or too great speed. 



The ventilation of the barn not yet completed, will be by means 

 of a simple covered opening, in the center of the peak for the 

 hay floor, and two more active ventilators, one at each end, com- 

 municating through wooden funnels, following the slope of the roof 

 on each side, and descending through the hay-floor and the cattle- 

 floor to the cellar. The manure cellar being entirely closed from 

 the outer air, the ventilating pipes can be supplied only by drawing 

 down the foul air of the cattle floor room, through the slatted floor. 

 I append herewith the specifications for the carpenter work, which 

 includes the sizes of the timbers. 



" All the materials for this building will be furnished by the 

 " owner, and the contractor is to put them together in the most 

 " thorough and workmanlike manner. The work of framing, rais- 

 " ing, and covering, including shingling sides and roof, to be com- 

 " pleted in thirty days from the time that the foundation walls are 

 " ready for the sills. 



" On the north side of building and wing the foundation wall will 

 " be carried up to height of under side of second story floor. On 

 " the south and ends the wall will be carried up one foot above the 

 " grade level, and on these there will be an 8 x 8 sill, the ends 

 " to be carrjed up to and built into north wall. 



" The summer-breasts in this floor will be tenoned into the sill 

 " on the south, and the north ends will rest on an 18-inch buttress. 

 " Each summer-breast will be supported on two piers, as shown on 

 " plan, and will be pinned to the sill. All these sticks will be 

 " 6x8, placed edgewise. 



" On the first floor and over piers there will be 6x8 sup- 

 " ports under two-inch flooring. 



" Corner posts 6x8, other posts 6x6, and one at every bay. 



" The girt will be 6 x 8 placed edgewise, and the beams of 

 " second story floor will be framed the same as those of first 

 " floor.
