64 Capt. Bonnycastle on some of the 
lands, and the country of the United States down to Lake 
George, again rises. Here a deposit of immense extent of 
beautiful red granite rears its head above the limestone range 
and forms Cedar Island, and the shores of Hamilton's Cove, 
while in the former place is observed, the unusual and unex. 
pected circumstance of the granite, and the limestone ming- 
ling with each other, and that so intimately as to appear, even 
in a stnall specimen, the result of contemporaneous fusion ; 
primitive limestone, therefore, exists here.* 
Kalm, the Swedish traveller, has noticed similaf#calcareous 
granites in this country, and one near the St. Lawrence, he 
particularly describcs as being composed of red felspar, black 
mica, white limestone with grains of purple or red quartz. Of 
another rock he says, that the absence of felspar is supplied 
by grey primitive limestone which, together with purple or 
garnet coloured quartz, and black mica it is composed of. 
It was supposed that the granitic range from the United 
States, and Thousand Islands terminated at Kingston, but I 
feel inclined to think otherwise, and that this granite spreads 
onwards towards the immense primitive range, which divides 
the waters flowing into Hudson’s Bay and the upper lakes 
from those which pay tribute to the mighty St. Lawrence. P 
The limestone of Kingston, contains in most instances but 
few shells and those mostly of one kind, a sort of scallop, 1. 
should not be atall surprized at some discoveries being wlti-, 
mately effected here with respect to animal “remains, as Has.

* Captain: Bonnycastle appears to alludeto this-rock in the following) 
extract from another communication of his: « Hereis the most singular 
junetion of the granite, with I think a talcose limestone ; these rocks actu- 
ally intermix so, that the quartz and felspar of the granite may be seen 
separately in the lime, and the lime separately in the granite, far beyond 
the line where the two masses have actually been soldered togetheras it 
were, This isall made evident by having a surface smoothed and polished. 
There is not much schorl here but Lhave scen a’ little in the granite 
in situ.»
