their noxious effluvia, and so strongly impregnated the water of the river, to the distance of one hundred and fifty miles below, that it could hardly be used for any purpose for a number of days.
"New Madrid, which stood on a bluff bank, fifteen or twenty-feet above the summer floods, sunk so low that the next rise covered it to the depth of five feet. The bottoms of several fine lakes in the vicinity were elevated so as to become dry land, and have since been plauted with corn ! " *

Mr. Bradbury, an English scientific explorer, who was on a keel boat passing down the river at the time, says:

"Immediately after the shock, we noticed the time, and found it near two o'clock in the morning of the 16th. In half an hour another shock came on, terrible, indeed, but not equal to the first." This shock made a chasm in the island, four feet wide and eight}' yards in length. After noticing successive shocks, the writer states ; "I had already noticed that the sound which was heard at the time of every shock, always preceded it at least a second, and that it always proceeded from the same point, and went off in an opposite direction. I now found that the shock came from a little northward of east, and proceeded to the westward. At daylight we had counted twenty-seven shocks, during our stay on the island."!
B. further records a series of shocks that continued daily, as be passed clown the river, until the 21st of December.
