[80] A plague of genuine yellow fever had visited New York in 1795, but in 1804 and 1805 the city suffered from a malignant fever of another type, and to such an extent that 27,000 persons, or one-third of the entire population, are said to have fled to escape the pestilence. This was possibly the malady which seized young Audubon not far from the beginning of the former year.

[81] The rough draft of a letter in English, evidently written by Lieutenant Audubon to be delivered by his son to the ship's captain, and probably in duplicate to his agent, Miers Fisher, but bearing no name or date, (Lavigne MSS.)

[82] See [Note, Vol. I, p. 98].

[83] The yearly rent of "Mill Grove" in 1804, according to the accounts of Francis Dacosta, who had then acquired a half interest in it, amounted to $353.34.

[84] "Mill Grove" farm is in Montgomery County, twenty-four miles northwest of Philadelphia, in the town known, after 1823, as Shannonville, but in 1899 rechristened "Audubon;" Norristown is five miles to the east.

[85] Mr. William H. Wetherill of Philadelphia, whose hospitality I have enjoyed and to whom I am indebted for many interesting facts and records pertaining to "Mill Grove." Samuel Wetherill, Mr. W. H. Wetherill's grandfather, was one of the first to bring "black rock," or coal, from Reading to Philadelphia. Samuel Wetherill, Junior, who is said to have started the first woolen mill in the country and to have produced the first white lead made in the United States, purchased "Mill Grove" for the sake of its minerals in 1813, the war having put a stop to all importations from England at that time. He actually succeeded in extracting several hundred tons of lead from the "Mill Grove" mines, doing better, it is thought, than any who preceded or followed him. Samuel Wetherill, Junior, died in 1829, and was succeeded in the lead and drugs industry by his four sons, of whom Samuel Price Wetherill became the owner of "Mill Grove" in 1833. The farm remained in the hands of the Wetherill family until 1876, and returned to them again, when the present owner came into possession, in 1892.

[86] In 1761 James Morgan, the first miller and builder, conveyed one-half of the mill site of five acres to Roland Evans, who came into possession of the other half, with the adjoining farm, in 1771; the property was sold to Governor John Penn in 1776; it passed to Samuel C. Morris in 1784, and to the Prevosts in 1786.

[87] The lease, which was drawn up in English, April 10, 1789, reads in part as follows: "This indenture, made on the tenth Day of April in the Year of our Lord, One thousand Seven hundred & Eighty nine, Between John Audubon, of the Island of St. Domingo, Gentleman, now being in the City of Philadelphia, of the one party, and Augustine Prevost...." The lease included the messuages, grist mills, saw mills, plantation and tract of land, which is described, tools, implements, stock, and furniture of the mills and farm, and was drawn for one year; it was signed in the presence of Miers Fisher, agent and attorney for Jean Audubon.

In the inventory were included one windmill, one pair of scales, with weights of 56, 28 and 7 pounds, "skreen," four bolting cloths, two hoisting tubs, and one large screw and circle for raising the millstones. This lease was renewed in October, 1790, when Jean Audubon, who was then living at Nantes, agreed to keep the house in good repair from that time onward. It was the Prevost mortgage that Miers Fisher paid but forgot to cancel (see [Vol. I, p. 122]); it was finally cleared up by Dacosta in October, 1806.

Miers Fisher's Philadelphia residence, called "Ury," which Audubon often visited, was near Fox Chase, now in the Twenty-third Ward. See Witmer Stone, Cassinia, No. xvii (Philadelphia, 1913).
