loam, like that of marl, is often used without conveying any 
very distinct idea of what is meant, either to the person who 
uses it or to the person to whom it is addressed, we will here 
explain, that wherever it has been used in this report, it has re 
lation to mixtures of clay and sand (the former in excess) ge- 
nerally coloured by iron, but containing no lime; in short an 
earth of which bricks are made. To avoid misconception, how- 
ever, the term has not been often introduced, Mere deposites 
of clay are often called marls, by which an erroneous idea of a 
country may be conveyed ; it should not be forgotten that the 
presence ef carbonate of lime is necessary to constitute a marl or 
marly clay, which is known by its effervescence in acid ; such a 
soil is of the best qualivy, whereas clays are proportionably in- 
fertile as they approach to a state of purity. 
Returning to the mouth of the inlet, our northerly course was 
resumed, and several hundred yards of a coast, composed of 
rocky points, jutting out into the lake, and enclosing fine sandy 
beaches between them, were examined. This, as has been be- 
fore said, is the character of the lake here, The remarkabl, 
uniformity aod simplicity of the rocks, hitherto met with, are 
worthy of notice. We could only make the following obser- 
yations which differ from what has been described—viz: kid- 
peys of the rock, coated with the brownish red powder we 
have before mentioned, were seen imbedded in the rock itself ; 
they were at first mistaken for pieces of magnetic iron—and a 
bed or broad vein of compact felspar, of a light yellowish green 
colour, was seen traversing the rock, contrasting strongly with 
its dark associate. It differed from those minerals which it 
most resembles, by yielding to the knife and fusing before the 
blowpipe, into a white blebby glass, like the rest of the felopars: 
The surface which had been exposed to the atmosphere, wa® 
decomposed, carious and of a reddish or yellowish white colour.
