Upon a footing course six inches tliick, 

 a wall of cement ( grout ) two feet high 

 and one foot thick was laid, as shown in 

 the section of the wall (Fig. 3). The 

 excavated soil was used for grading 

 against this on the outside and the grade 

 was brought to the top of the cement. 

 This kind of wall is coming quite com- 

 monly into use, many houses being built 

 of this material, with walls extending 

 three or four feet above the level of the 

 ground outside. If properly built they 

 will do service for a long time before 

 being eaten away by frost and moisture. 



On this wall a 2x6 inch jilank was 

 fastened by means of anchor bolts set in 

 the concrete. On this a hollow wooden 

 wall was placed two feet high and nine 

 inches thick. This wall consisted of two 

 by six inch studs, with building paper and 

 matched ceiling inside, and sheathing, 

 building paper, and siding outside. 

 ( Fig. 3. ) The side gutters were formed 

 of two by ten inch planks with narrow 

 strips nailed on to form the sides. This 

 costs less than a gutter made from one 

 piece, and will be fully as satisfactory. 

 The gutter between the houses required 

 a twelve inch plank, the gutter itself 

 being six inches in width. Anything 

 narrower would not be advisable. In 

 order to carry ofP the water the houses 

 were given a fall of two inches towards 

 the south. 



The roof was made of permanent sash- 

 bars placed one foot apart. They were 

 made of white pine and whitewood, 

 were eleven feet and three inches long 

 and lg-x2|^ in cross-section. The south- 

 ern cypress is being used largely in 

 greenhouse construction, and is con- 

 sidered very desirable for this purpose, 

 but if wdiite pine is used, with all joints 

 laid in white lead, and kept painted, 

 inside and oiit, it will prove very lasting. 

 Pine or any other wood, if not properly 

 painted, will soon rot out. 



With small glass, especially if sup- 

 ported at the frequent intervals, sash- 

 bars can be made as small as ^ of an inch 

 by 1^ inches, but 1x2, 1^x2, or lg-x2| wil 

 large houses. A ridge piece can be made
