thefe rocks are horizontal flabs or flat malTes P 
rifing out of the lake two or three feet above its 
furface, and feem an aggregate compofkion or 
concrete of fand, fhells, and calcareous cement, of a 
dark gray or dufky colour. The Rones are hard and 
firm enough for buildings, and ferve very well for 
light hand mill-ftones ; and when calcined afford a 
coarfe lime : they lie in vaft horizontal maffes 
upon one another, from one to two or three feet in 
thicknefs, and are eafily feparated and broken to 
any fize or form, for the purpofe of building. Rocky 
Point is an airy, cool, and delightful fituation, com- 
manding a moft ample and pleafing profpeCt of the 
lake and its environs ; but here being no wood, I 
re- embarked and failed down a little farther to the 
ifland in the bay, where I went on fhore at a mag- 
nificent grove of Magnolias and Oranges, defir- 
ous of augmenting my collections. I arofe early 
next morning, and after ranging the groves and 
favannas, returned, embarked again, and defend- 
ing, called at Mount Royal, where I enlarged my 
collections ; and bidding adieu to the gentleman 
and lady who refided there, and who treated me wick 
great hofpitality on my afcent up the river, arrived 
pi the evening at the lower trading houfe.
