Again he says: "I once ascended the spire of Strasburg Cathedral, which is the highest, I think, in Europe. It is a shaft of stone filigree-work, frightfully open, so that the guide puts his arms behind you to keep you from falling. To climb it is a noonday nightmare, and to think of having climbed it crisps all the fifty-six joints of one's twenty digits. While I was on it, 'pinnacled dim in the intense inane,' a strong wind was blowing, and I felt sure that the spire was rocking. It swayed back and forward like a stalk of rye, or a cat-o'-nine tails (bulrush) with a bobolink on it. I mentioned it to the guide, and he said that the spire did really swing back and forward, I think he said some feet. "Keep any line of knowledge ten years and some other line will intersect it. Long after I was hunting out a paper of Dumeril's in an old journal--the '_Magazin Encyclopédique_'--for _l'an troiséme_ (1795), when I stumbled upon a brief article on the vibrations of the spire of Strasburg Cathedral. A man can shake it so the movement shall be shown in a vessel of water nearly seventy feet below the summit, and higher up the vibration is like that of an earthquake. I have seen one of those wretched wooden spires with which we very shabbily finish some of our stone churches (thinking that the lidless blue eye of heaven cannot tell the counterfeit we try to pass on it), swinging like a reed in a wind, but one would hardly think of such a thing happening in a stone spire." Nor does he forget that dear little child he saw and heard in a French hospital. "Between two and three years old. Fell out of her chair and snapped both thigh-bones. Lying in bed, patient, gentle. Rough students round her, some in white aprons, looking fearfully businesslike; but the child placid, perfectly still. I spoke to her, and the blessed little creature answered me in a voice of such heavenly sweetness, with that reedy thrill in it which you have heard in the thrush's even-song, that I hear it at this moment. '_C'est tout comme unserin_,' said the French student at my side." [Illustration: THE BIRTHPLACE OF OLIVER WENDELL HOLMES.] The ruins of a Roman aqueduct he describes in another place, and now and then some incident that happened in England or Scotland, may be found among his writings; but when, after three years' absence, he returns to Cambridge and delivers his poem before the "Phi Beta Kappa Society," he begs his classmates to-- Ask no garlands sought beyond the tide, But take the leaflets gathered at your side. How affectionately his thoughts turned homeward is strikingly shown in the very first lines of the poem:
