As the wharf was not used fordockage, and lay somewhat behind thepierhead line, with the space in frontof it more or less spotted with submerged decided not to wait any longer for itssettlement and, also, to abandon the ideaof installing a drip en the Oakland side;instead, to at once raise the line, cut itand place an elbow in it so as to bringit to the wharf in the bottom of thedredged trench and then up and underthe wharf to the line on shore.
