Perhaps the pretended method of measuring lunar mountains was not interesting to laymen, but it may have been the cause of an intellectual tumult at Yale. At all events, a deputation from that college hurried to the steamboat and came to New York to see the wonderful supplement. The collegians saw Mr. Day, and voiced their desire. “Surely,” he replied, “you do not doubt that we have the supplement in our possession? I suppose the magazine is somewhere up-stairs, but I consider it almost an insult that you should ask to see it.” On their way out the Yale men heard, perhaps from the “devil,” that one Locke was interested in the matter of the moon, that he had handled the supplement, and that he was to be seen at the foot of the stairs, smoking his cigar and gazing across City Hall Park. They advanced upon him, and he, less brusque than Mr. Day, told the scientific pilgrims that the supplement was in the hands of a printer in William Street--giving the name and address. As the Yale men disappeared in the direction of the printery, Locke started for the same goal, and more rapidly. When the Yalensians arrived, the printer, primed by Locke, told them that the precious pamphlet had just been sent to another shop, where certain proof-reading was to be done. And so they went from post to pillar until the hour came for their return to New Haven. It would not do to linger in New York, for Professors Denison Olmsted and Elias Loomis were that very day getting their first peep at Halley’s comet, about to make the regular appearance with which it favours the earth every seventy-six years. But Yale was not the only part of intellectual New England to be deeply interested in the moon and its bat-men. The _Gazette_ of Hampshire, Massachusetts, insisted that Edward Everett, who was then running for Governor, had these astronomical discoveries in mind when he declared that “we know not how soon the mind, in its researches into the labyrinth of nature, would grasp some clue which would lead to a new universe and change the aspect of the world.” Harriet Martineau, who was touring America at the time, wrote in her “Sketches of Western Travel” that the ladies of Springfield, Massachusetts, subscribed to a fund to send missionaries to the benighted luminary. When the _Sun_ articles reached Paris, they were at once translated into illustrated pamphlets, and the caricaturists of the Paris newspapers drew pictures of the man-bats going through the streets singing “_Au Clair de la Lune_.” London, Edinburgh, and Glasgow made haste to issue editions of the work.
