Immigrations.—Independent of the Welsh and Germans, no large bodies of emigrants came to Pennsylvania during the first decade of its existence, except from England and some Quakers from Ireland. The prosperity of the new colony attracted settlers from other parts of British America and the West Indies; but nearly all, judging from the religious annals of the community, were either Quakers or in sympathy with them. In studying the Welsh emigration, John ap Thomas and his Friends: a Contribution to the Early History of Merion, Pa., by James J. Levick, M.D., should be read; see Pennsylvania Magazine of History, iv. 301. It is a history of the first company which came from Wales, in 1682. The History of Delaware County by Dr. George Smith contains much on the subject, with a map of the early settlements; cf. B. H. Smith’s Atlas of Delaware County, with a History of Land-Titles, Philadelphia, 1880. The agreement entered into between an emigration party from Wales and the captain of a vessel in 1697-1698 will be found in the Pennsylvania Magazine of History, i. 330.

The German or Dutch emigration can be studied in The Settlement of Germantown, and the Causes which led to it, by Samuel W. Pennypacker; see Pennsylvania Magazine of History, iv. 1. It is a thorough examination of the question, showing how the emigrants came from the neighborhood of Crefeld, a city of the Lower Rhine, near Holland. The several publications we have mentioned printed in Dutch and German must also be consulted. William Penn’s Travels in Holland and Germany, by Professor Oswald Seidensticker, already mentioned (see Pennsylvania Magazine of History, ii. 237), shows how naturally the event came about. Professor Seidensticker has also contributed “Pastorius und die Grundung von Germantown” to the Deutsche Pionier, vol. iii. pp. 8, 56, 78, and “Francis Daniel Pastorius” to the Penn Monthly, vol. iii. pp. 1, 51.

Special Subjects.—There remain a few monographs worthy of mention.

History of Manners and Customs of the Indian Nations who once inhabited Pennsylvania and the Neighboring States, by the Rev. John Heckewelder, Philadelphia, 1819, 8º. This work was first published as vol. i. of the Transactions of the Historical and Literary Committee of the American Philosophical Society. It was reprinted by the Historical Society of Pennsylvania, with notes by the Rev. William C. Reichel, in 1876, and forms vol. xii. of its Memoirs. Opinions regarding this work differ widely. It was favorably reviewed by Nathan Hale in the North American Review, ix. 178, and severely criticised by General Lewis Cass in the same publication, xxvi. 366. “A Vindication” of the History by William Rawle will be found in the Memoirs of the Historical Society of Pennsylvania, i. 258; 2d ed. p. 268. There is a portrait of Heckewelder in the American Philosophical Society, and a copy of it in the Historical Society; see Catalogue of Paintings, etc., belonging to the Historical Society, no. 85. As a further contribution to the aboriginal history, we may mention Notes respecting the Indians of Lancaster County, Pa., by William Parker Foulke; see Memoirs of the Historical Society of Pennsylvania, vol. iv. part ii. p. 189. This treats largely of the Susquehannocks.
