“In Geology strata overlying each other, in succession, as the bricks do when on their flat faces are called conformable, if they succeed, one over the other, with the edges or summits of the lower, abutting against the horizontal surfaces of the next, as do the bricks when they are placed in flat and vertical positions, in alternating strips, that is unconformability.

“If the strata are usually horizontal like the evenly piled series of bricks, they are called undisturbed; if inclined against each other, they are inclined, and they may make monoclinals, having one slope, or anti-clinals when they lean up against each other like the opposite sides of a peaked roof; or synclinal when inclined towards each other in an inverted position like the same roof overturned, with its ridge pole on the ground, and its inclined sides lifted into the air, or like the bricks in the last pattern of structure described.

“When we carry these similes into nature, we have all kinds of rocks, and we have them in mountains, in planes, and all the familiar configuration of the earth’s surface.
