Ant. III.—Remarks on the moving rocks of Salisbury. 
TO THE EDITOR. 
Dear Sir, 
In the winter of 1822, 1 sent you an anonymous communi- 
eation respecting the moving rocks of Salisbury, which was 
published in the 5th volume of the Journal of Science and 
In the last number of your Journal I observe some 
remarks on the same subject, by the Rev. J. Adams, Princi- 
pal of Charleston College, South Carolina. I have no wish,

heard to roar, not unlike the discharge ofa cannon. _I visited 
the spot immediately after, and was no longer in doubt re- 
specting the true cause of the movement of the rocks. On 
most of them the ice was piled up several feet in height, 
projecting from the side of the rock, next to the main body 
of the ice, towards the shore. Some which did not oppose 
so strong a resistance were evidently displaced, and the one 
in particular which I measured, was moved several inches,
