have heard of his submarine navigation during the war, and, from what Colonel Humphreys now tells me, I conjecture that the screw was the power he used. He joined to this a machine for exploding under water at a given moment. If it were not too great a liberty for a stranger to take, I would ask from him a narration of his actual experiments, with or without a communication of his principle, as he should choose. If he thought proper to communicate it, I would engage never to disclose it, unless I could find an opportunity of doing it for his benefit. I thank you for your information as to the greatest bones found on the Hudson river. I suspect that they must have been of the same animal with those found on the Ohio: and if so, they could not have belonged to any human figure, because they are accompanied with tusks of the size, form, and substance of those of the elephant. I have seen a part of the ivory, which was very good. The animal itself must have been much larger than an elephant. Mrs. Adams gives me an account of a flower found in Connecticut, which vegetates when suspended in the air. She brought one to Europe. What can be this flower? It would be a curious present to this continent. The accommodation likely to take place between the Dutch and the Emperor, leaves us without that unfortunate resource for news, which wars give us. The Emperor has certainly had in view the Bavarian exchange of which you have heard; but so formidable an opposition presented itself, that he has thought proper to disavow it. The Turks show a disposition to go to war with him; but if this country can prevail on them to remain in peace, they will do so. It has been thought that the two Imperial courts have a plan of expelling the Turks from Europe. It is really a pity, so charming a country should remain in the hands of a people, whose religion forbids the admission of science and the arts among them. We should wish success to the object of the two empires, if they meant to leave the country in possession of the Greek inhabitants. We might then expect, once more, to see the language of Homer and Demosthenes a living language. For I am persuaded the modern Greek would easily get back to its classical models. But this is not intended. They only propose to put the Greeks under other masters; to substitute one set of barbarians for another. Colonel Humphreys having satisfied you that all attempts would be fruitless here, to obtain money or other advantages for your college, I need add nothing on that head. It is a method of supporting colleges of which they have no idea, though they practise it for the support of their lazy monkish institutions. I have the honor to be, with the highest respect and esteem, Sir, your most obedient and most humble servant, Th: Jefferson. LETTER LXXIX.--TO JOHN ADAMS, July 28, 1785 TO JOHN ADAMS.
