   The reason why a mill-stone signifies confirmation from the Word in both senses, is, because wheat signifies good, and fine flour the truth thereof, hence by a mill-stone, by which wheat is ground into fine flour, or barley into meal, is signified the production of truth from good, or the production of what is false from evil, thus also the confirmation of truth or what is false from the Word; […]

   In North America the millstone grit, and a grey sandy and slaty rock beneath it, occur three times; and it is exceedingly difficult to distinguish these rocks in hand specimens, without the aid of organized remains. And remains are almost exclusively confined to the grey rocks. Common quarrymen, farmers, and foreign geologists, apply the names, greywracke and millstone, to all these rocks promiscuously; neither having observed their different relative positions.

   From the above account it will be seen how closely the Millstone Grit and the Lower Coal Measures are like one another in their lithological character. Each is a group of thick sandstones parted by shales, and in each beds of coal are very generally found on the top of the sandstones. The differences are these. Among the Millstones the sandstones are thicker, fewer, further apart, more constant both in size and character, and as a rule coarse grits or conglomerates.
