Machinery and boilers, wenches, tackle, and all useful equipment was loaded onto the power barge Bonita, in tow of the tug Priscilla, and shipped to San Francisco.

Strikes Sunken Rock and is Beached Near Arroyo La Cruz Creek. No One is Injured. Striking a submerged rock three miles north of Port San Luis shortly before noon yesterday, the Casco, a two mast schooler, knocked a big hole in her bow and Saturday night was on the beach at the mouth of Arroyo La Cruz creek. It was the opinion of Capt. Jacobson that owing to the high seas always running at this point that it will be impossible to get the boat off and that she will be pounded to pieces.

The Casco had been to Redondo, where she had discharged her cargo and was on the return trip to San Francisco. Without cargo for ballast she was running high and caught in a strong gale struck the rock before the pilot could avoid it.

Water began pouring in her hold but the ship’s pumps were used to good advantage and she was taken off the rock on her own steam. It was decided best to beach the craft and she was headed for shore.

There were nineteen aboard, constituting the crew. No one was drowned and none was injured. The captain and crew Saturday night came to San Luis Obispo and left on the midnight train for San Francisco. The Casco is 530 tons gross and valued at $65,000.

Yesterday afternoon the tug Liberty and a derrick barge of the San Francisco Bridge Co. were sent to the relief of the disabled vessel, but could not get near the wreck owing to stormy weather; the relief vessels putting into Morro bay for safety. An effort is being made today to reach the wreck and if nothing else can be done, it will be salvaged by the derrick barge, which will remove the engines, etc.

Eight members of the crew of the Casco, who have been at the Hotel Marre at the port, left this afternoon for San Francisco.
