Long afterwards I was hunting out a paper of Dumeril's in an old journal,--the "Magazin Encyclopedique" for l'an troisieme, (1795,) when I stumbled upon a brief article on the vibrations of the spire of Strasburg Cathedral.

A man can shake it so that 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's happening in a stone spire.

Does the Bunker-Hill Monument bend in the blast like a blade of grass?
I suppose so.
You see, of course, that I am talking in a cheap way;--perhaps we will have some philosophy by and by;--let me work out this thin mechanical vein .-- I have something more to say about trees.

I have brought down this slice of hemlock to show you.
