The main printed source respecting the Negro Plot of 1741 is the very scarce book by the recorder of the city of New York, Daniel Horsmanden, _A Journal of the proceedings in the Detection of the Conspiracy formed by some white people in conjunction with negro and other slaves for burning the City of New York, and murdering the inhabitants, etc., containing_, I., _a narrative of the trials, executions, etc._; II., _evidence come to light since their execution_; III., _lives of the several persons committed, etc._ (New York, 1744).[534] The history of Pennsylvania during this period is a tale of the trials of Penn,[535] the misgovernment of the province by representatives of the proprietors, the struggles of the proprietary party against the people, the apathy of the Quakers in the face of impending war, and the determination of the assembly to make the proprietors bear their share of the burdens of defence. The published _Pennsylvania Archives_ give much of the documentary evidence, and the general histories tell the story. The Pennsylvania Hist. Soc., in vols. ix. and x. of their _Memoirs_, published the correspondence of Penn with Logan, his secretary in the colony, beginning in 1700. This collection also embraced the letters of various other writers, all appertaining to the province, and was first arranged by the wife of a grandson of James Logan in 1814; but a project soon afterwards entertained by the American Philosophical Society of printing the papers from Mrs. Logan’s copies was not carried out, and finally this material was placed by that society at the disposal of the Penna. Hist. Society. The correspondence was used by Janney in his _Life of Penn_, and liberal extracts were printed in _The Friend_ (Philadelphia, July, 1842-Apr., 1846) by Mr. Alfred Cope. Mr. Edward Armstrong, the editor of the Historical Society’s volumes, gathered additional materials from other and different sources. A portrait of Logan is given in the second volume, which brings the correspondence down to 1711. The material exists for continuing the record to 1750, though Logan ceased to hold official connection with the province in 1738. Sparks (_Franklin’s Works_, vii. 25) says that “a history of James Logan’s public life would be that of Pennsylvania during the first forty years of the last century.” See the account of Logan in the _Penn and Logan Correspondence_, vol. i. The correspondence of Thomas and Richard Penn with a later agent in Philadelphia, Richard Peters, is also preserved. In 1861 this correspondence was in the possession of Mr. John W. Field, of Philadelphia, when Mr. Charles Eliot Norton gave transcripts of a portion of it (letters between 1750 and 1758) to the Mass. Hist. Society.[536] Of an earlier period, when Evans was deputy-governor, there are some characteristic letters (1704, etc.) in a memoir of Evans communicated by E. D. Neill to the _N. E. Hist. and Geneal. Reg._, Oct., 1872 (p. 421).
