its outer edge. This gives the width of the space 

 or hollow in the side walls. The plate may be 

 constructed of a 2x3 or 2x4 scantling, placed 

 edgewise. The boards which constitute the side 

 walls are nailed to the sides of the plate and 

 to the sides of the strip which was nailed to the 

 top of the sill. Rough lumber may be used for 

 the side walls, if strict economy is desired. The 

 inner boarding should be nailed on first and cov- 

 ered on the outside with tarred building paper. 

 This paper will be within the wall when it is 

 completed. It is preferable to fasten the paper 

 in place by means of thin strips, laths, pieces of 

 thin boards, etc., rather than to depend wholly 

 on the heads of tacks or nails. The outside board- 

 ing may now be put on, and the cracks between the 

 boards covered with inexpensive battens, if they 

 are secured with small nails at frequent intervals. 

 If cheapness is of considerable importance, the 

 ordinary building laths may be used, and will 

 answer the purpose admirably, although some- 

 what heavier battens will be more durable. A 

 mistake is sometimes made in selecting heavy 

 battens which will not draw down by nailing as 

 well as lighter ones. The battens on the outside 

 boarding and the tarred building paper on the 

 inside boarding make two coverings, each of 

 which is impervious to wind, with an air space 

 between them.
