After doing so, they threw off the line between the two tiers and again boarded the "Carroll," which backed away from the outside barge, preparatory to "drilling" out the barge she was after in the tier off the Public Pier. She had only got about seventy-five feet away when the tier off Pier 52 broke adrift because the fasts from the "Anna C," either rendered, or carried away. The tide and wind carried down the six barges, still holding together, until the "Anna C" fetched up against a tanker, lying on the north side of the pier below — Pier 51 — whose propeller broke a hole in her at or near her bottom. Shortly thereafter: i. e., at about 2:15 P.M., she careened, dumped her cargo of flour and sank. The tug, "Grace," owned by the Grace Line, and the "Carroll," came to the help of the flotilla after it broke loose; and, as both had syphon pumps on board, they could have kept the "Anna C" afloat, had they learned of her condition; but the bargee had left her on the evening before, and nobody was on board to observe that she was leaking. The Grace Line wishes to exonerate itself from all liability because the "harbormaster" was not authorized to pass on the sufficiency of the fasts of the "Anna C" which held the tier to Pier 52; the Carroll Company wishes to charge the Grace Line with the entire liability because the "harbormaster" was given an over-all authority. Both wish to charge the "Anna C" with a share of all her damages, or at least with so much as resulted from her sinking. The Pennsylvania Railroad Company also wishes to hold the barge liable. The Conners Company wishes the decrees to be affirmed.
