What reading level is The Vailan Or Annular Theory a Synopsis of Prof in Vails Argument in Suppo book?
To quickly assess the difficulty of the text, read a short excerpt:
17 vegetable product coal would form very slowly, but from the Vailan system would require but a few hours, or days at most, to lay it down.
Plants found in coal burn with difficulty, which ought not to be true if they contained a resinous sap, or bituminous matter. In many instances you can find a dozen fossil plants in the overlying clay to where you can find one in coal. They are clay fossils because they are imbedded in clay, same as fos- sils in coal are carbon because im- bedded in carbon....
If coal is compressed peat, as some would have us believe, why do we not find fibres runnning vertically through it? You may examine peat after a pressure of twenty tons to the square inch has been exerted, and yet the vertical structure of the mass will be apparent. Since we find abundance of rootlets run- ning in all directions, vertically as well as horizontally in the under clays of coal beds it is evident that coal is not a metamorphosed peat.
Imagine an expanse of marshes 100, 000 square miles in extent, cov- ered with calamites, ferns, sigillaria lepidodendra remaining motionless for countless centuries, and' then suddenly sinking beneath the waves of the sea in order to receive a sear formed bed for a covering; and in the universal burial to preserve but a few fossils, and they in a horizontal position, while in the clays immedi- ately above and below the coal beds they are found in profusion; that in due time the vast area arose from its baptism, and on the thin layer of clay millions of the same plants grew until they formed another bed of coal, when it sinks again beneath the waves, and this oscillation con- tinued until it had been buried twenty, forty or one hundred times, and you have the old theory of how coal was formed.
