Sunday 19th remained to await my Baggage.
The 20th remained, and being obliged to stay, watched the Process of manufacturing Salt. The Wells for getting the salt water are dug to a depth of about . . . feet. Muddy clay is met with to a depth of . . . feet. Then . . . feet of slatey rock. When the rock is pierced the salt water is found at a depth of more than . . . feet. This slate burns in the fire as if impregnated with bitumen or entirely made up of that substance. Bones of those great marine bodies that are rather frequently met with on the banks of the Ohio have been found in the impure clay that was dug up to reach the slatey rock.
