The Floor Framework.
The tops of the 2 – by – 4 corner posts A must be notched as shown in Fig. 544 to receive the ends of the floor framework pieces B. Having the width and length dimensions given you in Fig. 543, you can locate the proper positions for the corner posts A. Dig the post holes 18 inches deep. Be certain that the posts line up correctly before you fill in around them. They may look right, yet be enough out of the way to throw the entire framework out of square. The proper way to do is to fasten pieces B in the notches in the tops of the posts, after the posts have been dropped into the holes, then fasten pieces C to their ends, with one nail driven part way in.
Test the corners one at a time with a square, and, when you have corrected any error that you may find, nail a temporary diagonal brace across the tops to hold the pieces rigid. When all corners are correct, spike all members in place. Lay the Floor short-ways of the framework. With it in place, build the walls. Make The Side Walls in sections like that shown in Fig. 545. Cut the plate D and corner uprights E and F, of the dimensions indicated, and place them flat upon the ground; block up the ends and center, if necessary, to make them level.
Spike together the ends of these pieces, then nail about four of the side boards to them. Trim off the tops of uprights E and F so top plate G will rest squarely upon them, and spike the top plate in place. Then finish nailing on the remaining wall boards. Having completed one wall, turn it over so the framework members will be uppermost, place the framework members of the opposite wall upon them, nail on the siding, and you will have the second wall a duplicate of the first, only reversed.
