366 deny that it could be applied, more particularly in those critical circumstances to obviate which was the chief aim of his own project. "In such cases," said he, " as that disastrous event which happened lately, of the wreck of a whole fleet upon a lee shore, off the coast of Spain, every fire on board must be extinguished, and of course such an engine could be of no use." Mr Taylor was not daunted by these objections, but, on the contrary, the more he thought of the project, the more convinced he became of its practicability. He represented to Mr Miller, that, if not applicable to purposes of general navigation, it might at least prove useful on canals and estuaries. After many conversations, the latter gentleman at length conceded so far to Mr Taylor's suggestion, as to request him to make drawings, for the purpose of showing how the engine could be connected with the paddle-wheels. Mr Taylor did so, and Mr Miller, being still farther satisfied, though as yet, it appears, unconvinced, agreed to be at the expense of an experiment, provided it should not amount to a large sum, and that Mr Taylor should superintend the operations, as he candidly confessed he was a stranger to the use of steam. The two projectors were then at Dalswinton; but it was arranged that, when they should return to Edinburgh in the early part of winter, an engine should be constructed for the purpose. Part of the summer was employed by Mr Miller in drawing up a narrative of his experiments upon shipping, with a view to its being printed and circulated. This he submitted to Mr Taylor for the benefit of his correction; and the latter gentleman, observing that no mention had been made of the application of the steam engine, "I have not done that inadvertently," answered Mr Miller, "but from a wish not to pledge myself to the public for a thing I may never perform: you know my intentions on that subject are as yet conditional." Mr Taylor replied, that he could hardly look upon them in that light, as he was satisfied that any expense which could attach to so small a matter would not prevent him (Mr Miller) from making the experiment; that he considered the mention of the steam engine as of importance; and that it could be alluded to in such a manner as to pledge him to nothing. Mr Miller was convinced, and introduced an allusion to steam, as an agent he might perhaps employ for the propulsion of his vessels. Copies of the paper thus improved were transmitted to the royal family, the ministers, many of the leading members of both houses of parliament, and to all the maritime powers in Europe, besides the president of the United States of America.

In November, 1787, Mr Miller removed as usual to the capital, and Mr Taylor, having been empowered by his employer to proceed about the construction of an engine, recommended to Mr Miller's notice a young man named Symington, who had attempted some alterations upon the steam engine, and was now residing in Edinburgh for his improvement in mechanics. It was agreed that Symington should form an engine on his own plan, and that the experiment should be made in the ensuing summer upon the lake of Dalswinton. The construction of the engine occupied several months, and was not completed at the conclusion of that session of the university; so that Mr Taylor was detained in town, to superintend the operations, for some time after his pupils had returned with their father to the country. When all was ready, he proceeded with Symington to Dalswinton, where, on the 14th of October, 1788, the experiment was made in the presence of Mr Miller and a considerable concourse of spectators. The boat was a double one, and the engine, which had a four inch cylinder, was placed in a frame upon the deck. The experiment was successful beyond the most sanguine wishes of any of the parties concerned. The vessel moved at the rate of five miles an hour, and neither was any awkwardness found in the connexion of the engine with the wheels,
