Ferns, Sigillariæ, Calamites, and the usual plants of the carboniferous flora, may be found in every coal-mine; and the Devonian limestones of the South of Ireland yield ferns and Lepidodendra. In Forfarshire the lower Devonian shales abound in the foliage of aquatic, apparently fluviatile, plants.[190]

A list of some of the most productive British localities is subjoined.

In addition to the suggestions already given as to the mode of collecting specimens, it may be necessary to state that the leaves in the tertiary marls and clays are generally very delicate and friable, and liable to flake off in the state of a carbonaceous film. This may, in a great measure, be prevented by carefully covering them with a thin coating either of mastic varnish, or gum-water, before they are placed in the cabinet. In extracting these specimens, a broad chisel will be found the most convenient instrument. In searching for fossils in coal-mines, the collector should remember that the ironstone nodules often contain beautiful examples of the leaves of ferns, and fruits of Lepidodendra. These nodules, when of an oblong shape, should be split open in a longitudinal direction, by a smart blow of a hammer, and the inclosed leaf will thus be exposed, as shown in [Lign. 3, figs. 2, 3], ante, [p. 69].

[191] Fruits and Fern-leaves have been collected here by Mr. Becklesand stems of a species of Arundo, by Mr. Alfred Woodhouse.

[192] In collecting Stigmariæ, the student should particularly attendto the relation existing between these fossils and their supposedstems; for it is probable that roots of this type will be found tobelong to other genera, besides Sigillaria, and Lepidodendron (ante,[p. 136].).

The above list must, of course, be considered as merely suggestive: many other localities are mentioned in the previous notices of the fossil genera.
