DEAR FRIEND,
Upon my arrival here, I had once more the mortification to find myself in the neighbourhood of the yellow fever, which had lately been imported. The uncommon, early, and severe north-west winds entirely prevented it from spreading; a fortunate circumstance for the inhabitants of Boston, as, from the narrowness of their streets, great population, and other circumstances, it must have been very fatal, had it not been by this means destroyed.
In order to give you the most regular account of this disorder I could procure, I must repeat several circumstances from former letters.
The yellow fever, which has lately been so fatal, is a new disorder, first brought to the West Indies, in a slave-ship from the coast of Africa, late in the year 1792. It spread rapidly from island to island, and in July, 1793, was first imported to the continent in a french schooner to Philadelphia. The physicians of that city, naturally concluding it was the usual yellow fever of the West Indies, applied the common remedies in that case: viz., bark, and other astringents. In nine cases out of ten, death was the inevitable consequence to all who took these medicines. The disease was equally fatal to the faculty. A universal despondency took place, till doctor Rush, suspecting this was a new disorder, applied an opposite method of cure, by mercurial medicines, and copious bleedings; which, when administered in the first or second stage of the disorder, had the desired effect.
I send you an extract from the doctor's pamphlet, wherein he explains his motives for adopting this method of cure, &c.
Speaking of the effect of the lancet, he says, "It was at this time my old master reminded me of Dr. Sydenham's remark, that moderate bleeding did harm in the plague, where copious bleeding was indicated, and that, in the cure of that disorder, we should leave Nature wholly to herself, or take the cure altogether out of her hands."
The truth of this observation was obvious:—By taking away as much blood as restored the blood-vessels to a morbid degree of action, without reducing this action afterward, pain, congestion, and inflammation, were greatly increased; all of which were prevented, or occurred in a less degree, when the system rose gradually from the state of depression which had been induced by indirect debility. Under the influence of the facts and reasonings which have been mentioned, I bore the same testimony in acute cases against what was called moderate bleeding, that I did against bark, wine, and laudanum, in this fever.—I drew from many persons seventy or eighty ounces of blood in five days.

After the cold weather had completely destroyed this disorder, it did not appear again in the United States till the next year, when it was imported to Baltimore and New Haven; a distance from each other of more than five hundred miles. The cold weather again destroyed it, till carried, in 1795, to Charleston and New York, equally distant from each other; and this summer it was imported to Charleston, New York, Boston, and Newbery Port; a distance of one thousand five hundred miles along the coast; but fortunately the early N.W. winds destroyed it in all these places before it had made any considerable progress.
A quarantine upon vessels from the infected islands would effectually prevent the importation of this plague; but if performed in the literal sense of the word, it would materially hurt the West India trade of the Americans.
You have little to fear from this disorder being brought to England; experience has clearly proved, this fever cannot exist in a cold climate; but was it to be imported to the south of Europe, the consequences would be dreadful indeed. I before told you, the negroes were not afflicted with the yellow fever, though universally employed as nurses to the sick.
A disease that will affect but one species of men is not new. About the year 1652, a very dreadful and uncommon plague ravaged this part of America, and actually extirpated several nations of the Indians, without, in a single instance, affecting the white emigrants, though continually among them. This strange circumstance the fanatics of New England accounted for in their usual way, as appears from several of their sermons, still preserved:—
"It was a just judgment of God upon these heathenish and idolatrous nations; the Lord took this method of destroying them, that he might make the more room for his chosen people." A philosopher would perhaps demand a better reason. Apropos of philosophers—An american writer has been endeavouring to investigate the age of the world, from the Falls of Niagara! According to his calculation (which, by the by, is not a little curious) it is 36960 years since the first rain fell upon the face of the earth!
Yours, &c.

DEAR SIR,
I before hinted to you, that the Americans pay very little attention to their fisheries.
Exclusive of the shad fishery, which is only two months in the year, there is not one individual, either in the city of Philadelphia, or it's vicinity, who procures a livelihood by catching fish in the Delaware, though that river abounds with sturgeon, perch, cat-fish, eels, and a vast variety of others, which would meet with a sure sale in the Philadelphia markets: but this is a trifle to their neglect of the greatest fishery in the universe; for such certainly is that on the banks of Newfoundland.
The Americans now being at peace with most of the piratical states of Barbary, will find an excellent market for their fish in the Mediterranean. This circumstance may induce congress to pay some attention to the hints thrown out by Dr. Belknap, in his Account of the American Newfoundland Fishery, which I transcribe for you perusal:—
"The cod-fishery is either carried on by boats or schooners. The boats in the winter season go out in the morning, and return at night. In the spring they do not return till they are filled. The schooners make three trips to the banks of Newfoundland in a season; the first, or spring cargo, are large, thick fish, which, after being properly salted and dried, are kept alternately above and under ground, till they become so mellow as to be denominated dumb fish. These, when boiled, are red, and of an excellent quality; they are chiefly consumed in these states. The fish caught in the other two trips, during the summer and fall, are white, thin, and less firm; these are exported to Europe and the West Indies; they are divided into two sorts; one called merchantable, and the other Jamaica fish.
"The places where the cod-fishery is chiefly carried on, are the Isle of Shoals, Newcastle, Rye, and Hampton. The boats employed in this fishery are of that light and swift kind called whale-boats; they are rowed either with two or four oars, and steered with another; and being equally sharp at each end, move with the utmost celerity on the surface of the ocean. The schooners are from twenty to fifty tons, carry six or seven men, and one or two boys. When they make a tolerable voyage, they bring over five or six hundred quintals of fish, salted and stowed in bulk. At their arrival, the fish is rinced in salt water, and spread on hurdles composed of brush-wood, and raised on stakes three or four feet from the ground. They are kept carefully preserved from the rain: they should not be wet from the time they are first spread on the hurdle till they are boiled for the table.
"This fishery has not of late years been prosecuted with the same spirit it was fifty or sixty years ago, when the shores were covered with fish-flakes, and seven or eight ships were annually loaded for Spain or Portugal, beside what was carried to the West Indies. Afterward they found it more convenient to cure the fish at Corscaw, which was nearer to the banks. It was continued there to great advantage till 1744, when it was broken up by the french war. After the peace it revived, but not in so great a degree as before. Fish was frequently cured in the summer on the eastern shores and islands, and in the spring and fall at home.
"Previously to the late revolution the greater part of remittances were made to Europe by the fishery; but it has not yet recovered from the shock which it received by the war with Britain: it is however in the power of the Americans to make more advantage of the cod-fishery perhaps than, any of the european nations. We can fit out vessels at less expense, and by reason of the westerly winds, which prevail on our coasts in February and March, can go to the banks earlier in the season than the Europeans, and take the best fish. We can dry it in a clearer air than the foggy shores of Newfoundland and Nova Scotia. We can supply every necessary from among ourselves; vessels, spars, sails, cordage, anchors, lines, hooks, and provision. Salt can be imported from abroad cheaper than it can be made at home, if it be not too much loaded with duties. Men can always be had to go on shares, which is by far the most profitable way, both to the employer and fisherman. The fishing banks are an inexhaustible source of wealth; and the fishing business is a most excellent nursery for seamen; it therefore deserves every encouragement and indulgence from an enlightened and rational legislature."
