124 Mr. Farey’s Notes on Mr. Bakewell’s Geology. 
[P.192] very slow steps; patient investigation of the facts, and just 
reasonings upon them, such as the physical astronomers 
have persevering applied, in a century which is past, will 
certainly be rewarded with results in this science, of no or- 
vapeaetl interest to our Race, I venture to think, see my note 
n p. 328.

200, 1. 19, worn by attrition *.—* Between the high moun- 
tains at the eastern end of the Caledonian Canal in Inver- 
nessshire, the largest quantity of alluvial Clay seems lodged, 
interspersed with a few huge Bolders, which I have perhaps 
any where seen] (see my Note on page 52): to me it seems 
probable, after conversing with Mr. Thomas Telford on the 
subject, as to the ficts of these and other parts that I had 
not seen, that the immensely deep Lakes in the line of this 
Canal, may be parts of a valley or chasm, as deep as these 
Lakes, which once opened into the German Ocean, and 
that enough of this alluvium has since been lodged, not only 
to fill up the eastern end of this valley, to its present level, 
but even 100 or 150 feet higher, until a subsequent excava- 
izon therein, took place, and left a tablet of this Clay, 
skirting the mountains, to nearly the same level, for great 
distances, as monuments of its state at one period. The 
vast 
q The allavial chalky Clays of England, which I have mentioned, in 
Bedfordshire and other places, see my Note on p. 52, appear very liable to be 
mistaken by, and to mislead observers, who have not accurately studied the 
circumstances attending sfrutification, in the same school with the practical 
sinkers or the superintendants of Coal Pits, and other deep excavations (see 
my Note on p. 44); to which classes of Men the distinction is perfectly 
known, and evident (however difficult it may be to define the same, so as 
to fnstract or even to draw the attention of learned Geognosts, to those di- 
stinctions): and the alluvium of the surface, whatever its thickness, or 
the téchnical or local Name by which it is distinguished (as Alluvium, 
Bareing, Callow, Clay [mixed], Clearing, Corn-soil, Cover, Corn-clay, 
Earth-cover, Giax el, Gingle, Keale, Loose-earth or soil, Ratchel, Ridding, 
Rock-cover, Rubbis a Rub hile, Rimmel Sammel, Sand [mixed ], Scale, 
Skerry, Soil, Ter, Till, Top- earth, &e. &c.) is perfectly known by them 
from the regular s.rata ( eneath these disturbed matters, of whatever kinds, 
or whatever Names such undisturbed matters may be known by, in the 
district (as Fast-country, earth, rock or soil, Measures, Metals, Mine, 
Revular-measures, Rock, Shelf, Strata, Undistucbe d-gronnd, whole-ground, 
&c. &c.) And among these Men, the merest novice would be ashamed of 
making such blunders on this essential head, as have gravely been published 
to the world, as to red Marl with Shells in it, on Chellaston Hill, (see my 
Note on p. 176), Chalk strata in Huntingdonshire and Rutlandshire (note 
on p. 259), &c. 
I strongly suspect, that what Mr. Webster in your last volume, page 325, 
calls the Chalk Marl (notwithstanding that this name was already ae
