Note 85 — Chapter VII · FIRST VISIT TO THE UNITED STATES, AND LIFE AT "MILL GROVE"

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.
