The next experiment was attempted in December, with the new constructed boiler, but the violence of the heat was so great, from the steam, that it melted the soft solder that great part of the machine was put together wuth, and rendered it entirely useless, until repaired with hard solder ; about this time the ice drifting, carried off the boat which the machinery was made ibr, and destroyed her in such a manner, that the repairing her was equal to one half of the expense of building a new one : That the boat was, in the spring, 1787 repaired, the machine also, and was ready for trial in September, when the boat moved up the river, against the current, with about two tons on board, besides the machinery, at the rate of two miles per hour ; but the new boiler was so badly made, that it opened at several of its ioints, which let gi-eat quantities of the steam escape : and the said Barns further saith, that to his Knowledge, the machine at the last trial, on December 3, 1787, was very imperfect in many parts, as the same boiler was then made use of, after receiving some repairs : It is his opinion it may be brought to answer very valuable purposes, as it will be simple, cheap, light and durable, and may be applied to a ship of the largest size to advantage, having no external application whatever. And the said Barns further saith, that M^ Rumsey has, to his Knowledge, injured his circumstances very much, by quitting all kinds of business to pursue the boat ; that he the said Barns, has received of the said Rumsey five pounds per month besides his board, from April, 1785, to the present time ; which in his opinion, is but a small part of the expenses the said M^".
