this storm that day at 139°W. Someone later charted the storm to . These points suggest a trajectory toward the Big Island of Hawaii. 1847 A tropical cyclone existed On October 24 of this year. 1849 A system existed on June 21 and 22. 1850 Eight systems are recorded. I. One existed on an unknown date. II. On or about 24 June 1850, the Joseph Butler encountered a "severe gale of wind" near , 260 miles from the coast of Mexico, which carried away her main-mast (sailing). III. On 5 August 1850, the barque Como encountered a "severe gale" at , commencing at north and veering to west and south. She "lost sails and bulwarks and sustained much other damage." These winds suggest that the vessel traveled on the left side of the track of the storm, which passed to its northwest. IV. On 9 September 1850, a "hurricane" at , about south of Acapulco, dismasted the Niagara. For five hours on 11 September 1850, the Diana at experienced a "severe hurricane" from the northeast, veering to southwest; the vessel "hove on beam-ends." The veering intense wind suggests that the hurricane passed slightly northwest of the vessel, which experienced the left side. If a hurricane progressed from Niagara to Diana (and the ships logged their dates accurately), then the hurricane moved between west-northwest and northwest at . V. On 26 September 1850, a "severe gale" at threw the Laura on her beam-ends, and she lost cargo. VI. On 3 October 1850, the brig Amazon, sailing from New York northward for San Francisco, encountered a "severe hurricane" at . A passenger on the brig published an account of this storm. Heavy rain accompanied squalls from southwest, which increased in frequency and intensity until 5 pm, when a "hurricane" commenced with the brig under reefing fore-topsail and mainsail. The captain "scudded" the vessel, putting her before the blast. The tempest raged through the night with momentarily increased fury. The wind veered from southwesterly to southerly to southeasterly to easterly to northeasterly to northerly to westerly to southwesterly, making the circuit of "thirty-four points" of the compass in 6 hours. This account suggests a small, violent hurricane moving less than ; the Amazon probably actually overtook the hurricane from its southeastern quadrant and traveled through the eyewall almost completely around the eye of the storm. At 4 am on 4 October 1850, the
