of sand, 5 yards of gravel and 200 concrete 

 blocks. 



The roof for this house is one concrete 

 slab. No doubt this can best be 

 structed by mak- 

 ing a form within 

 the building of 

 the desired shape 

 and putting on 

 the concrete the 

 same as was done 

 in making the 

 other one on the 

 barn floor. It will 

 require some in- 

 genuity to make a 

 form for the edge, 

 however. Nail 

 boards together 

 in an L-shape, 

 making four pairs 

 of them and form- 

 ing a huge frame 

 around the upper 

 part of the blocks 

 of the wall and 

 properly support- 

 ing it, to form the 

 proper eave for 

 the roof. 



For either house, use ventilators in the 

 center of the roof slab. These should be 

 put in when making the slab. 



The curve of the walls of this house 

 is obtained by using shaped silo tiles. 

 It is covered with a concrete slab

Shoring up a Porch-Post to 

 Repair Floor-Boards 



HAVING to repair some floor boards 

 under and about a porch-post it was 



necessary to 



shore up the post. 

 This is the meth- 

 od I used. I first 

 laid a piece of 

 2-in. plank about 

 8 in. wide on the 

 ground and with 

 a similar plank 

 a trifle longer 

 than the distance 

 to the plate of 

 the porch, I made 

 a slanting brace 

 or support. With 

 an iron bar hav- 

 ing a flattened 

 end I raised the 

 post up a little at 

 a time by lifting 

 on the end of the 

 plank and push- 

 ing it to a more 

 vertical position. 

 This was not 

 much of a job, 

 raised and the work 

 without a 



the post was 

 was satisfactorily completed
