One thousand brick weigh 5,000 to 5,500 pounds and 

 occupy 43 . 2 cubic feet. 



Hollow tile. Hollow tile are laid in the same manner as 

 brick. They are now 

 made with ample 

 strength to carry all 

 loads except where a 

 beam or joist may 

 be placed upon them . 

 When it is necessary 

 to place beams and 

 joists upon hollow 

 tile walls, the beams 

 or joists should ex- 

 tend over the whole 

 width of the wall up 

 to 8 inches. It may be necessary to make the wall solid 

 with concrete or fill the tile with concrete for one, 

 two, or three courses below the point of bearing. This, 

 however, is seldom necessary in farm buildings. If hollow 

 tile is used for footing or foundations directly exposed 

 to the weather and frost, it is advisable to select the hard- 

 burned tile for this zone. There is a great deal of difference 

 in the burning of clay products. 



Windows and doors. In house construction both windows 

 and doors are purchased ready to hang. Barns and other 

 outbuildings may have homemade doors, but rarely a win- 

 dow constructed by the carpenter. 



Windows. Window sash are made in three thicknesses: 

 ijriyi^i, and 1 % inches. The 1 Y% thickness is what is known 

 as standard. It is used for all residences and most barn 

 construction. It is heavy enough to carry the ordinary 

 size panes of glass. The iyi thickness is used for cellar 

 sash sizes. The heavy sash is used in large buildings, where 

 greater strength is required. Unless otherwise specified, 

 the i$/& thickness is always supplied, except in the small
