the intervening water for conducting the reverberations ; the po- 

 sitions, on the opposite shore, chosen by the gunner and bugle- 

 man, for giving the primary sound ; and the place of the " Sta- 

 tion of Audience,^ for obtaining the most happy combinations 

 of the direct sound and the echoes. 



The surface from whence the principal echoes are derived, is 

 a rock of a pyramidal form, rising almost perpendicularly from 

 the verge of the stream, to the height of 1200 to 1300 feet. 

 The base is covered with wood, which, from its general even- 

 ness of surface, quietness of repose, and elasticity of foliage, 

 may possibly reflect and modulate, instead of absorbing, the im- 

 pression received from the air by the action of the gun and the 

 bugle. There is likewise, if I mistake not, a slight depression 

 or concavity in the surface of the rock, immediately above the 

 thickest of the wood, by which a concentration of the returning 

 sound may probably be produced. Such is the source of the 

 principal echoes. 



The annexed eye-draught of the relative position of the dif- 

 ferent arrangements, may assist in the explanation and descrip- 

 tion of the phenomena. 



In this sketch, A, is the " Station of Audience ^ P, the po- 

 sition of the ordnance ; B, the station of the bugleman ; and E, 

 the chief reflecting surfaces of the Eagle's Nest. 



When the paterera is fired, the echoes being given from a va- 

 riety of surfaces on the Eagle's Nest, and more remotely from 

 the distant faxies of the majestic mountains, the ^' Mangerton** 

 and the " Turk," produce not only a return of the sound of the
