About the same time, Sir S. Morland, another experimenter, estimated the expansive force of water at 2000 times, in which he was not far from the truth. England, however, was not the only country to produce inventors. One Blasco de Garay, who flourished a hundred years before the Marquis of Worcester, is declared by his champions to have been the first to solve the problem of propelling a vessel by steam-power. But investigations as to the accuracy of the story tend to the belief that he did nothing of the kind, and that the beautifully circumstantial account of his experiment does greater credit to the imagination of the narrator than to his regard for accuracy.[6] De Garay’s experiment was made at Barcelona in the year 1543 in the presence of representatives of the Emperor Charles V. Ravago, the Treasurer, reported to the Emperor that the vessel would go two leagues in three hours, but that the machine was complex and expensive, and that the cauldron in which the steam was generated might burst. This is exactly the report which a cautious financier, presumably not an expert in mechanics, might be expected to make. Other reports were more favourable to the project, the commissioners appointed for the purpose ascribing to the vessel a speed of a league an hour. What has been established beyond question, however, is that De Garay made the experiment with a boat fitted with paddle-wheels, but that the wheels were turned by men and not by steam. [6] Mr. John McGregor reported to the Society of Arts that the claim that De Garay used a steam-engine is unfounded, human power being used.
