Practical Hints

be the corner of the building, measure off from this on the line of the established 

 side 66', and drive a nail accurately into some sort of wooden stake, which would be 

 point B. Then take two tapes and put the ring of one about the nail at A and 

 the ring of the other about the nail at B and stretch them in the direction of C. 

 By making the distance on the A tape 49^' and that on the B tape 82^', the inter- 

 section of the tapes at these points will be the true point, C, 

 and the triangle thus formed will be a true right-angled triangle. 

 This may be made on the smaller scales of 9', 12' and 

 15' and of 3', 4' and 5'. Carpenters often use wooden squares 

 made on the 3', 4' and 5' sizes. 



Roofs. An ordinary roof 20' x 40' is 800 square feet. The 

 largest amount of water in gallons that 

 one may expect to collect from it may be 

 roughly determined by multiplying one- 

 half the area in feet by 7.10. Therefore 

 it is possible to get 2,840 gallons from 

 the above roof; 1,480 gallons is, however, 

 about the average quantity. 



It is not advisable to make a roof 

 pitch than 30. The lower pitches are 

 is used, and such should be covered

Shaving Bay. For the shaver who has cut himself often, through the poor 

 provisions of the ordinary house, Fig. 62 is offered as a consolation and a balm. It 

 can be varied to suit the taste, but its principle seems good. It is simply a bay 

 about 6' wide, adjoining the bathroom and having one door into it and another 

 into the hallway. A mirror is affixed to the front side and lighted by windows 

 from the right and left. A shelf is built to connect from one side to the other 

 and is fitted with a washbowl on one side; drawers are placed underneath where 



desired. This shelf should be about 

 the height of an ordinary washbowl and 

 the window stool should sit upon it. The 

 top of the mirror itself should not be 

 more than 6' 4" high, and a light placed 

 at the top and close to it. Another light 

 should be placed about eighteen inches 

 to the left of the mirror (b), so that it 

 can be used at night and receive light 

 from both sides. The razor strop can 

 be hung under the slight projecting shelf 

 in front of mirror (a). 



This scheme seems practical for 

 both the large and the small house. It 

 can be made a part of the bathroom, in 

 which case the tub could be placed across the inner end and the toilet be made a 

 separate room, as it should be in any case. Each should have a separate entrance.
