of different degrees of thickness, and then a very shallow coal, varying from one to three feet; it is very sulphurous, and, with the exception of what is used in the immediate neighbourhood, is converted into cokes. It seems to be a general opinion among the miners, that there is a deep coal formation, but that the expence of working it would be so great, as not to pay the proprietors.
Some of the springs contain large quantities of carbonate of lime in solution, which is precipitated when the water reaches the surface; occasionally, large masses of tufa are formed.
Vegetation is at least a fortnight later in the clay district than where the sand prevails, but, on the other hand, the autumnal flowers continue several weeks later in the former than they do in the latter.
It is natural to suppose that, in such a varied surface, a variety of botanical specimens would be met with. The following are most of the medicinal, together with some of the scarcer plants:─
| Anthyllis vulneraria. | Daucus Carota. |
| Antirrhiuum Orontium. | Digitalis purpurea. |
| Arum maculatum. | Drosera rotundifolia. |
| Atropa Belladonna. | Erin Tetralix. |
| Butomus umbellatus. | Gentiana Amarella. |
| Campanula patula. | Gentiana campestris, |
| Campanula hederacea. | Geranium phæum. |
| Campanula Intifolia. | Galanthus nivalis. |
| Cardamine impatiens. | Glechoma hederacea |
| Colchicum autumnale. | Helleborus viridis. |
| Comarum palustre; | Helleborus foetidus. |
| Conium maculatum. | Hyoscyamus niger. |
| Couvallaria majalis. | Hypericum dubium. |
| Cornus suecica. | impatiens Noli-me-tangere |
