Bevels and mitresin forms are expensive, and; in man;cases, wholly unnecessary. It does notappear to be generally recognized thatit is often cheaper to use a little more A Foundation for a Medium LengthPlaner With Pilasters for the LevelingBlocks is diagrammed in Fig. 3. Foun-dations of this type have been con-structed in certain shops. The provisionof the pilasters, however, requires ex-pensive form work, the excess cost ofwhich does not appear to be justified.

This foundation issimply a rectangular prism of concretereinforced with steel. Wedges insteadof leveling blocks are shown on the topto support the planer bed, although, asoutlined above, leveling blocks are us-ually preferable. Where the earth isself-sustaining, a foundation like that ofFig. 1 can (as is described below) be builtwithout any forms by merely filling with• concrete a rectangular excavation in Where the earth is not self-sus-taining and forms are necessary, it is -£sgK Z^/V?
