We have just had a week of the finest weather imaginable, dry, bright and breezy, and with uninterrupted sunshine. The greater part of our hay crop has, in consequence, been secured in splendid condition, without a drop of rain, in fact--a piece of rare good fortune in Lochaber. We do not know if the extraordinary aspect of the sun at its rising and setting on Monday, the 13th instant [June 1870], was noticed elsewhere by any of our readers. On the morning of the day in question it presented a strangely mottled, yellowish copper-coloured disc, so singularly unusual as to induce an old seaman, nearly eighty years of age, in our neighbourhood, to call our attention to the circumstance. In the evening a little before its setting, it assumed a lurid blood-red colour, which was very remarkable, and forcibly reminded us at the moment of Scott's lines in Rokeby-- "No pale gradations quench his ray, No twilight dews his wrath allay; With disc like battle-target red, He rushes to his burning bed, Dyes the wide wave with bloody light, Then sinks at once--and all is night." We were unanimous in predicting an immediate and violent storm of wind and rain, but the next morning came in bright, breezy, and cloudless, and such it has continued ever since. Such phenomena, and the nature of the weather following them, are always worth recording. Virgil, in his first Georgic instructs the husbandman to confide in those indications of the weather afforded by the aspect of the sun, for the rather curious reason, however, that the obscuration of the solar orb gave faithful warning of the impending fate of Cæsar! A very striking instance of a form of sophism, well known to the logician, in which an accidental circumstance is assumed as sufficient to establish efficient connection. On the morning of Wednesday last we had a smart touch of frost here in exposed situations--a strange and anomalous phenomenon in the dog-days truly! But when we remember that Mr. Glaisher (who for purely scientific purposes has put his life into greater peril than any other living man), in his recent aerial ascent met with a regular snow-storm at the elevation of only about one mile above the earth's surface, we shall not wonder so much, perhaps, that a frost current should, under certain circumstances, occasionally penetrate earthwards even in the dog-days. We should have stated above that on the 13th we carefully examined the solar disc with an excellent four-feet telescope belonging to Ardgour, when it presented only two "spots" or maculæ, and neither of these of remarkable size or form, situated close together on the orb's south-western limb.
