Hoover Dam construction: diversion tunnels: "Steel frame carriage supporting form for 110 degree top-arch concrete in diversion tunnel lining. Note jacks and wedges by means of which form is placed in position and lines up. The surface of the top concrete is painted with an asphaltic coating immediately upon removal of the forms, to prevent the too rapid dissipation of the concrete's moisture content." 6/30/32; B. D.
