A Well Known Master Mariner Lost At Sea

Capt. Charles Mockler was a passenger on the ill fated steamer, Discovery, lost off Yakutat during the first days of November last. The steamer left Nome with a passenger list of 29. None of these are supposed to have been lost as their final destinations were reached previous to the loss of the steamer. Capt. Mockler boarded her at Kodiak returning to Seattle, where he resided. On October 30th, the steamer left Yakutat, the last port at which she called, for Seattle, and was never seen again. Life preservers marked "Discovery" were picked up on the shore, and other wreckage, which go to show that she went down with all hands on board, among them, Capt. Mockler. Capt. Mockler was a brother of Capt. Patrick Mockler of Brule, Colchester County, Nova Scotia. He was well known as a successful ship master and general favorite. He at one time sailed as master of the barque "James Bain" and afterwards purchased the schooner "Lizzie Dyer" and had her outfitted for sealing in the Behring Sea.

He was a successful man in all of his undertakings, and deservedly so, for he paid strict attention to business, and practiced fair and honest dealing; while his open, genial manner attracted the respect and good will of his acquaintances. His wife and three children reside at their home in Seattle.

More Wreckage from Steamer Discovery

Doors, Life Preservers and other Articles Found on Middleton Island

Yesterday's P-I gives news that pieces of the steamer Discovery has been found on the beach of Middleton Island, in the Copper River section of Alaska. The find was made November 17, according to information received by Walter Storey, a merchant of Kodiak, Alaska.

Under data of Kodiak, April 16, Storey writes: "I have just discovered information from parties that reside on Middleton Island that wreckage was picked up on the beach of that island on the 17th of November 1903. The current in that locality is such that it is evident she was lost on the south end of Kayak Island.

The wreckage found included: One door marked "purser's room"; one door marked "toilet"; one door plain; top of after house and several life preservers marked steamer Discovery. "These articles looked as though they had only been in the water several hours".

The Discovery is supposed to have been lost off the mainland coast a few hours out of Yakutat, the last port she made. She was never seen after leaving Yakutat, November 2. On the 9th of the month, Yakutat miners bound for Kayak found wreckage, including life preservers marked "Discovery" at the mouth of the Seal river. About twenty-five people went down with the vessel or were lost as the result of her foundering or breaking to pieces.
