This bed and others of similar character at the Joggins, have given us much information respecting the nature and mode of growtli of these plants, which I may pause here to notice in detail. The Calamites were tall cylindrical stems, with a hard outer bark, and were either hollow or filled with cellular matter. The stems were regularly marked with longitudinal stria) or furrows and cross joints, sometimes showing the marks of the attachment of the leaves, which were verticillate, or in whf ris around the stem, and long and needle-like (Figs. 37 and 38).
