A TREE OF IRON.
At a recent meeting of the Academy of Natural Sciences in Philadelphia Professor Carter gave an account of a wonderful tree trunk discovered in a sandstone quarry in Montgomery county. Pa. It is ten inches thick and eighteen feet long, and baa been turned into iron through a natural process of substitution, by which the wood has been replaced with iron hemitate derived from the sand. This is analogous to the transformation into agate undergone by formerly submerged tree trunks in Arizona and the Yellowstone Park.
