"In the State of Jersey, neither of these cases has taken place; no shipping arrive there, and consequently there has been no embankment for the purpose of wharfs, and the yellow fever has never broke out in Jersey, This, however, does not decide the point, as to the immediate cause of the fever; but it shews that this species of

fever is not common to the country in its natural state; and I believe the same was the case in the West Indies, before embankments began, for the purpose of making wharfs, which always alter the natural condition of the ground; no old history, that I know of, mentions such a disorder as the yellow fever.

"A person seized with the yellow fever in an affected part of the town, and brought into the healthy part, or into the country and among healthy persons, does not communicate it to the neighbourhood, or to those immediately around him: Why then are we to suppose it can be brought from the West Indies, a distance of more than a thousand miles, since we see it cannot be carried from one town to another, nor from one part of a town to another, at home? Is it in the air-this question on the case, requires a minute examination. In the first place, the difference between air and wind is the same as between a stream of water and a standing water. A stream of water, is water in inotion; and wind, is air in motion. In a gentle breeze, the whole body of air, as far as the breeze extends, moves at the rate of seven or eight miles an hour; in a high wind, at the rate of seventy, eighty, or an hundred miles an hour: when we see the shadow of a cloud gliding on the surface of the ground, we see the rate at which the air moves, and it must be a good trotting horse that can keep pace with the shadow, even in a gentle breeze; consequently, a body of air, that is in and over any place of the same extent as the affected part of a city may be, will in the space of an hour, even at the moderate rate I speak ot, be moved seven or eight miles to keward, and its place, in and over the city, will be supplied by a new body of air coming from a healthy part seven or eight miles distant the contrary way, and then on in continual succession. The disorder, therefore, is not in the air considered in its natural state, and Bever stationary. This leads to another consideration of the case.

body of air moves off, it will impreg nate eyery succeeding body of air, however pure it may be when it arrives at the place.

"The result from this state of the case is, that the impure air, or vapour, that generates the yellow fever issues from the earth, that is, from the new made carth, or ground raised on the muddy and filthy bottom of the river; . and which impregnates every fresh body of air that comes over the place, in like manner as air becomes heated when it approaches or passes over fire, or becomes offensive in smell when it approaches or passes over a body of corrupt vegetable or animal matter in a state of putrefaction.

“The muddy bottom of ¡ivers contains great quantities of impure, and often inflanimable air, (Carburetted Hydrogen gas) injurious to life; and which remains entangled in the med till let loose from thence by some açcident. This air is produced by the dissolution and decomposition of any combustible matter falling into the water and sinking into the mud, of which the following circumstance will serve to give some explanation:

"In the fall of the year that New York was evacuated (1783), General Washington had his head quarters at Mrs. Berrians, at Rocky-Hill, in Jersey, and I was there:-the Congress then sat at Prince-Town. We had several times been told, that the river or creek, that runs near the bottom of Rocky-Hill, and over which there was a mill, might be set on fire, (for that was the term the country people used); and as General Washington had a mind to try the experiment, General Lincoln, who was also there, undertook to make preparation for it against the next evening, Nov. 5th. This was to be done, as we were told, by disturbing the mud at the bottom of the river, and holding something in a blaze, as paper or straw, a little above the surface of the water.

Each party held first vapour that flew off would be huto his opinion, and the next evening mid, it extinguished the candle; but the experiment was to be made. after applying the candle three or four times, the vapour that issued out began to flash: we then tied a bladder over the mouth of the barrel, which

When the mud at the ed into the phial; we then put the bottom was disturbed by the poles, the air bubbles rose fast, and I saw the fire take from General Washington's light, and descend from thence to the surface of the water, in a similar manner as when a lighted candle is held so as to touch the smoke of a candle just blown out, the smoke will take fire, and the fire will descend and light up the candle. This was demonstrative evidence, that what was called setting the river on fire, was setting the inflammable air on fire, that arose out of the mud.

"We put a lighted match into the phial, and the air or vapour in it blazed up in the manner of a chimney on fire: we extinguished it two or three times, by stopping the mouth of the phial, and putting the lighted match to it again; it repeatedly took fire, till the vapour was spent, and the phial be came filled with atmospheric air.

"First:-The yellow fever is not a disorder produced by the climate naturally, or it would always have been here in the hot months; the climate is the same now as it was fifty or an hundred years ago: there was no yellow fever then, and it is only within the last twelve years that such a disorder has been known in America.


Secondly:-The low grounds on the shores of the rivers, at the cities, where the yellow fever is annually generated, and continues about three months without spreading, were not subject to that disorder in their natural state, or the Indians would have for saken them; whereas, they were the parts most frequented by the Indians in all seasons of the year, on account of fishing. The result from these cases is, that the yellow fever is produced by some new circumstance not common to the country in its natural state, and the question is, what is that new circumstance?

"It may be said, that every thing done by the white people, since their settlement in the country, such as building towns, clearing lands, levelling hills, and filling up vallies, is a new circumstance, but the yellow fever does not accompany any of these new circumstances. No alteration made on the dry land produces the yellow fever; we must therefore look to some other new circumstances; and we come now to those that have taken place between wet and dry, between land and water.

from the river by embankment, there are upwards of eighty new wharfs made since the war, and the much greater part within the last ten or twelve years; the consequence of which has been, that great quantities of filth or combustible matter deposited in the muddy bottom of the river contiguous to the shore, and which produced no ill effect while exposed to the air, and washed twice every 24 hours by the tide-water, have been covered over several feet deep with new earth, and pent up and the tide excluded. It is in these places, and in these only, that the yellow fever is produced.

"Having thus shewn, from the circumstances of the case, that the cause of the yellow fever is in the place where it makes its appearance, or rather, in the pernicious vapour issuing therefrom, I go to shew a method of constructing wharfs, where wharts are yet to be constructed, as on the shore of the East River, at Corlder's Hook, and also on the North River, that will not occasion the yellow fever, and which may also point out a method of removing it from places already infected with it. Instead, then, of embanking out the river and raising solid wharfs of earth on the mud bottom of the shore, the better method would be to construct wharfs on arches built of stone; the tide will then flow in under the arch, by which means the shore and the muddy bottom will be washed and kept clean, as if they were in their natural state without wharfs.
