HOLLOW BLOCXS FOR WALLS. 



I want to inquire if any of the read- 

 ers of the Review have had experience 

 with giflonhouse walls built of hollow 

 concrete blocks? There is a concern in 

 my town which makes a popular patent 

 building block, using sharp sand and 

 Portland cement. Tl^ blocks have open 

 spaces and when laid up make what may 

 well be called a hollow wall.^ The mak- 

 ers claim it to be nonporous and hence 

 frost and dampness proof. The blocks 

 are 8x9x24 inches and the makers claim 

 it is cheaper than any other kind of 

 good wall. Posts for gutter supports 

 need be only about thirty inches lone, 

 1^/^-inch pipe set into the wall and made 

 secure by cement. I intend remodeling 

 my houses and making some additions 

 and want to use the best material. If 

 anyone has used such hollow blocks for 

 walls I should be glad to have him give 

 his experience. J. H. S. 



GLAZING AND PIPING. 



I am thinking of building another 

 house this spring and would like to know 

 which you would recommend, butted or 

 lapped glass? In my houses the putty 

 does not stay; it falls out like flour. 

 The new house is to be 18x70 and about 

 ten feet to the ridge, running north and 

 south. How many runs of pipe will be 

 needed to maintain 60 degrees under 

 Massachusetts weather conditions? The 

 hole in the heater is for a 4-inch pipe. 



R. S. H. 



In a humid climate like Massachusetts, 

 where the mercury reaches a low de- 

 gree several times during the winter, I 

 do not think it would be wise to use 

 butted glass. It is almost impossible to 

 make a tight roof with butted glass. If 

 good 'putty is used and the work is done 

 during warm weather and the sash bars 

 kept well painted both outside and in- 

 side there should be no diflBculty in 

 maintaining a tight roof with lapped 

 glass. With lapped glass, however, no 

 lap should be more than one-eighth of 

 an inch wide. If I read your question 

 aright, that you wish to use 4-inch pipe, 

 six ruis arranged so as to place a loop 

 under each of the three benches will be 

 sufficient to maintain a temperature of 

 60 degrees provided the furnace heats 

 the water to 180 degrees. L. C. C.
