stalks, and whatever light matters were in its way, and circling, perhaps, wider and stronger for a time, has borne them onward and upward toward the heavens, where at length its force was dissipated, and it mingled with the surrounding air. Similar movements were excited along the southern limits of the storm area, which we are describing; and hence, not one cyclone, but more properly speaking, a multitude of little cyclones--tornadoes independent of each other, but dependent on the main current, or great eastward traveling storm center--swept through points in Illinois, Missouri, Tennessee and Kentucky; all rushing toward the line of the lowest barometrical depression, the actual and advancing storm center. Not since the Signal Service had been established had the barometer at St. Louis stood so low as 28.46, which, reduced to sea-level, means 29.08. Toward this region of rarefied air--this partial vacuum--the cyclonic movements from the south rushed with inconceivable fury, and as the nucleus of the storm was rapidly moving eastward, the cyclonic movements were turned from a north to a northeast course. All these varied movements simply result from the effort of a disturbed atmosphere to restore an equilibrium. The illustration of the fire used above also affords a good example of the way rotation may result from rising air. Any one who has watched a great fire in calm weather knows that sparks and smoke do not rise straight up, but in spirals and whirls, the warmer centers rising faster, just as the middle of a stream flows faster than the edge. But the powerful winds and the damage done were not all the work of the marginal whirlwinds. A storm center moving so rapidly must necessarily have carried a steady high wind. Leaving Wyoming, by Wednesday evening the storm was in the middle of Colorado; on Wednesday night, it moved well into Kansas; on Thursday, it crossed States of Missouri and Illinois, and Thursday night it was passing over Indiana. The climax of energy was apparently not attained until the storm reached Illinois. In Missouri, more or less damage was done to fences and buildings, from Sedalia to St. Louis. At the former place, a roof or two was blown off, and the teachers in one of the schools were so alarmed that they dismissed the children. Jefferson City, sixty miles further on, made a record of damaged roofs and shattered windows. At St. Louis, there was a deluge of rain at three o’clock in the afternoon, lasting a half hour; and the wind blew with fury during the evening and greater part of the night. It drove in and smashed some plate-glass windows, blew off an occasional roof, and from the top of the corner of St. Patrick’s School, hurled to the sidewalk a stone weighing, probably, four hundred pounds.
