232 APPNNDIX C : STRATIFICATION OF HACK NESS HILLS 
which support it being of their full thickness it forms the highest in- 
terior land, but which is much below the marginal contour formed by 
the Calcareous Grit beneath the Coralline Oohte. 
Thus by a superficial survey of the characteristic development of 
each stratum, I have made out the ranges and width of a considerable 
pile of strata which have also been locally and extensively identified 
by their organised fossils, to which as they are arranged in the Scar- 
borough Museum and to the account published by PhilUps and others 
I must refer, and I may add that by the characteristic distinctions 
herein employed and others peculiar to the terminating edges of the 
different strata, many Geological maps of the largest scale be made 
of Districts, Parishes, Estates, or Farms, which by readily exhibiting 
the varieties of soil, and indacing a better knowledge thereof, would 
be very interesting and instructive to the owners and occupiers and 
generally beneficial to the agricultural interest. October 2nd, 1830.
