I, being desirous to see the Machine they made use of, we hoisted out a Boat, and Mr. Banks, Dr. Solander, and myself went on board her, where we was show’d it. It was made of Canvas, in every respect like an Umbrello; its Circumference, if extended to a Circle, was 24 feet, tho’ this was a Small one of the Sort; yet Captain Elliot told me that it would hold as much as 150 Men could haul. I was so well satisfied of the Utility of this Machine that I would not have delayed a moment in having one Made had not our Forge been render’d Useless by the loss of some of its parts.
