Theexcavation reached a depth of 8 or 9 feet, though in someplaces the muck extended downward for 35 feet. Theexcavated material was used as topsoil and supportedphenomenal growths after a years decomposition. Toremove it three methods were adopted—first, by meansof derricks; second, by means of tram cars; and third,by the assistance of a traveling cableway. In Figure 35,page 109, are shown three derricks with the black muck inadjacent piles. This of course had afterwards to be dis-tributed over the finished subgrade. In the background is.
