[Footnote: Written by Mr Strickland, of Douro.] “In my hunting excursions and rambles through the Upper Canadian forests, I had frequently met with extensive wind-falls; and observed with some surprise that the fallen trees lay strewn in a succession of circles, and evidently appeared to have been twisted off the stumps. I also remarked that these wind-falls were generally narrow, and had the appearance of a road slashed through the forest. From observations made at the time, and since confirmed, I have no doubt that Colonel Reid's theory of storms's a correct one, viz., that all wind-storms move in a circular direction, and the nearer the centre the more violent the force of the wind. Having seen the effects of several similar hurricanes since my residence in Canada West, I shall proceed to describe one which happened in the township of Guelph during the early part of the summer of 1829. “The weather, for the season of the year (May), had been hot and sultry, with scarcely a breath of wind stirring. I had heard distant thunder from an early hour in the morning, which, from the eastward, is rather an unusual occurrence. About 10 A. M., the sky had a most singular, and I must add a most awful appearance, presenting to the view a vast arch of rolling blackness, which seemed to gather strength and density as it approached the zenith. All at once the clouds began to work round in circles, as if chasing one another through the air. Suddenly the dark arch of clouds appeared to break up into detached masses, whirling and mixing through each other in dreadful commotion. The forked lightning was incessant, accompanied by heavy thunder. In a short time, the clouds seemed to converge to a point, which approached very near the earth, still whirling with great rapidity directly under this point; and apparently from the midst of the woods arose a black column, in the shape of a cone, which instantly joined itself to the depending cloud. The sight was now grand and awful in the extreme. Picture, to your imagination a vast column of smoke, of inky blackness, reaching from earth to heaven, gyrating with fearful velocity--bright lightnings issuing from the vortex; the roar of the thunder--the rushing of the blast--the crash of timber--the limbs of trees, leaves, and rubbish, mingled with clouds of dust, whirling through the air;--you then have a faint idea of the scene. “I had ample time for observation, as the hurricane commenced its devastating course about two miles from the town, through the centre of which it took its way, passing within fifty yards of where a number of persons, myself among the rest, were standing, watching its fearful progress. “As the tornado approached, the trees seemed to fall like a pack of cards before its irresistible current. After passing through the clearing made around the village, the force of the wind gradually abated, and in a few minutes died away entirely.
