There were other prostrate trunks so completely petrified as to be hard as adamant ; and the steps leading up to one of the temples were carved out of the fossilized remains of trees. Here, then, there evidently existed a highly fossiliferous stratum ; and it was a source of deep regret to the Commissioner and myself that time and opportunity did not admit of further exploration in that interesting locality.
It was interesting to see how silica or iron pyrites can particle by particle permeate through the interstices of animal and vegetable tissues, thoroughly reproducing and replacing their lineaments to the minutest particular. A transverse section of one of these trunks would present the same appearance as woodapith, medullary rays and concentric circles, and from the last named one could obtain a fair estimate of its age.
Once organized, endowed with sap and a circulation, giving out oxygen- and absorbing carbonic acid, and performing a number of other functions, it became, under special conditions, nothing but a mould for the deposit of inorganic material, which permeated its structure by some almost inexplicable molecular attraction.
Constant wear had so told on these steps, that they were slippery to a degree ; and, armed as we were with heavy boots, great caution was necessary when descending them.
