The Sigillaria (seal-marked) is curiously ornamented with vertical ribs, along each of which is a row of seal-like impressions. These are the scars left where the leaves fell off. They wind in a spiral around the trunk. The roots (stigmarice) are also dotted with scars. They are generally found separate, though sometimes combined with the parent tree.

The scars are arranged diagonally or in a quincunx order. 5. Conifers, or cone-bearing trees, were not infrequent, with their boughs laden with fruit. Such was the vegetation which flourished in the Carboniferous Age, and which we now use to warm and light our houses and to drive our engines. II.

These little creatures had probably crept into the hollow trees for shelter, and were overtaken by the convulsions which overwhelmed them. Several true reptiles have since been identified. Traces of the spider, cockroach, scorpion, and May-fly with gauze wings 7 inches broad, have...
