"It often happens that the careless observer has, for the first time, his attention called forcibly to some appearance of nature by accidental circumstances: if at all superstitious, he immediately prognosticates the most disastrous consequences from that which a little observation would have convinced him was but a phenomenon a little more conspicuous than usual. The northern lights are said to have caused much consternation when first observed; and they have lately been viewed with more than ordinary interest, as it appears from the _Newcastle Chronicle_, the last autumn (1830), when they were more than usually brilliant, some of the inhabitants of Weardale were convinced they saw, on one occasion, very distinctly, the figure of a man on a white horse, with a red sword in his hand, move across the heavens; and are, no doubt, now certain that it foretold the present eventful times. Even this belief may be accounted for on such accidental coincidences, or even philosophically, by assuming as a fact that this phenomenon is the result of an electrical change in the atmosphere, and that such a change usually precedes rain. Now, if such happen in spring or in summer, and before such a quantity of rain as is found to affect the harvest, it may too often betoken scarcity, discontent, and turbulence, as such are the times when all grievances, either real or imaginary, are brought forward for redress. The origin of the superstition of sailors, of nailing a horse-shoe to the mast, is to me unaccountable, unless it may have been, like the following trial of the credulity of the superstitious by some person for amusement:--Sailors sometimes make a considerable pecuniary sacrifice for the acquisition of a child's caul, the retaining of which is to infallibly preserve them from drowning. "Some years ago, a pretty wide district was alarmed by an account of the beans [Fàba vulgàris var. equina] being laid the wrong way in the pod that year, which most certainly foreboded something terrible to happen in a short time, and this produced much consternation amongst those who allow their imaginations to run riot. The whole of the terrible omen was this: the eye of the bean was in the pod towards the apex, instead of being towards the footstalk, as might appear at first sight to be its natural position; and some were scarcely convinced that this was the natural position of the beans in the pod ever since the creation, even on being shown the pod of the preceding year with the seed in the same position. "As yet, however, I fear we must sum up in the words of Davy:-- "_Phys._ But how can you explain such absurdities as Friday being an unlucky day, and the terror of spilling salt, or meeting an old woman?
