Climate. Owing to the irregularity of its soil and surface, in conjunction with other causes, there is no inconsiderable difference in the climate of Shropshire. On the eastern side of the county, when the land approaches nearer to a plain, the harvest is frequently ripe about a fortnight sooner than in the interior, where the valleys are extensive, the surface more dense, and the bottom of clay. And yet in this part, both hay and grain are gathered earlier than on the western side, where the valleys are narrow, and the land frequently more elevated; though here, the land is not so stiff, and lies for the most part on a rocky bottom, full of fissures. In spring the easterly winds prevail, and in autumn those from the west. In the opinion of Archdeacon Plymley, the easterly winds are more regular, than those from the west; generally blowing for a series of five or six years; and then, for nearly the same space of time, being less frequent, and less violent. The same may be observed of the wet and dry seasons; but the periods of both appear to be much shorter. The air is generally very salubrious, - not only through the country at large, but even in the mining districts.
