cooled, condenses what rises next at B, which Hair Straighteners condenses that at C, and that condenses what is rising at D, the cold operating by the contact of the vapors faster in a right line downwards than the vapors can climb in a spiral line upwards; they climb, however, and as by continual addition they grow denser, and, consequendy, their centrifugal force greater, and being risen above the concentrating currents thaGhd Hair Straightenerst compose the whirl, fly off, spread, and form a cloud.It seems easy to conceive, how, by this successive condensation from above, the spout appears to drop or descend from the cloud, though the materials of which it is composed are all the while ascending.TGhd Straightenershe condensation of the moisture, contained in so great a quantity of warm air as may be supposed to rise in a short time in this prodigiously rapid whirl, is perhaps, sufficient to form a great extent of cloud, though the spout should be over land, as those at Hatfield ; and if the land happens not to be very dusty, perhaps the lower part of the spout will sghd mk4 stylercarce become visible at all; though the upper, or what is commonly called the descending part, be very distinctly seen.The same may happen at sea, in case the whirl is not violent enough to make a high vacuum, and raise the column, &c. In such case, the upper part A B C D only will be visible, and the bush, perhaps, below. 1 But if the whirl be strong, and there be much dust oghd iv stylern the land, and the column W W be raised from the water, then the lower part becomes visible, and sometimes even united to the upper part. For the dust may be carried up in tNFL Jerseys Youthhe spiral whirl, till it reach the region where the vapor is condensed, and rise with that even to the clouds : and the friction of the whirling air, on the sides of the column W W, may detach great quantities of its water, break it into drops, and carry them up in the spiral whirl mixed with the air; the hNFL Jerseys Wholesaleeavier drops m NFL Jerseys Authenticay, indeed, fly off, and fall; in a shower, round the spout; but much of it will be broken into vapor, yet visible; and thus, in both cases, by dust at land, and by water at sea, the whole tube may be darkened and rendered visible.As the whirl weakens, the tube may (in appearance) separate in the middle; the column of water subsiding, and the superior
