In order to institute a comparison between the cost of electricpower as has just been set forth and the cost of power generated by-steam or producer gas, the following tables have been compiled aftera careful study of data availahle in teehnical journals and also fromdata collected by the Commissions engineers in various towns withinthe district under consideration. The capital costs have been com-piled from information supplied by various makers of engines andether machinery. The tables represent average w^orking conditionsand assume a high-class installation.
