218 Miscellaneous Localitres of Minerals. 
Bowlders, with these marks upon them, I have observed, 
not only in this town, but in Manchester, Ellington, and Wil- 
braham. 
I think we cannot account for these appearances, unless 
we call in the aid of ice along with water, and that they have 
been worn by being suspended and carried in ice, over rocks 
and earth, under water. 
It is stated in the Edinburgh Encyclopedia, Vol. XIII. p. 
426, that ‘fields of ice sometimes rise from the bottom, and 
bring with them masses of rock, of several hundred tons 
weight. These masses of stone are imbedded in the ice, 
they are carried along with the ice, and deposited on shores 
ata great distance from their original situation.” 
Similar ideas are expressed in the same work, Vol. Xf. 
p- 70. 
I mention these appearances on Bowlders of sandstone in 
this vicinity, in order that in other places, if similar appear- 
ances exist, they may be noticed. Such observations may 
lead to probable conclusions respecting the transportation of 
Bowlders, and the formation of banks of earth.

with a number of interesting localities of Minerals, which 
have not as yet been published. Fora part of the localities, 
we are indebted to Mr. Joel Baily, a zealous and industrious 
mineralogist, of ast Marlborough, who has considerably pro-
