On Saturday morning, two New Zealanders, named Jackey and Tommy were brought before the Police under the following circumstances. Our readers will recollect that the Achilles whaler, on her entering the port, reported, that she had picked up four New Zealanders in a whale boat at sea, badly wounded; they told cock-and-bull story that they belonged to the Ploughboy (whaler) from Nantucket, and had been cut adrift and fired at by the Captain for having while in chase of a whale, missed some strokes and so frightened the fish away; their story, however improbable, was in a measure credited till Friday evening, when, in consequence of some intelligence by one of the vessels which came in on that day, that she had spoken the Ploughboy, and had been informed that some New Zealanders had committed murder on board — taken to a boat and had been fired at, when pulling from the ship, Captain Duke, gave the men into custody on the charge of murder.
