For the provisions of such a bill--the abolition of slavery and of servitude until twenty-eight--compensation of owners--permission for negroes to remain slaves if they so desired--_cf. House Report_ no. 399 (1826); _J. of H., 1825-1826_, pp. 370, 375, 396, 497, 498. Also _J. of S., 1841_, vol. I, 249, 294. [261] The numbers were 1790, _3737_; 1800, _1706_; 1810, _795_; 1820, _211_; 1830, _67_; 1840, _64_ (?). The U. S. Census Reports do not mention any after 1840, but it is said that James Clark of Donegal Township, Lancaster County, held a slave in 1860. _Cf._ W. J. McKnight, _Pioneer Outline History of Northwestern Pennsylvania_, 311. It is necessary to remark that the U. S. Census reported _386_ as the number of slaves in 1830. As this was in increase of 175 over the number reported in 1820, it aroused consternation in Pennsylvania and amazement elsewhere, so that a committee of the Senate was immediately appointed to investigate. Their account showed that there had been no increase but a substantial diminution in numbers; and that the U. S. officers had been grossly careless, if not positively ignorant in their work. _J. of S., 1832-1833_, vol.

Narrative of Facts in the Case of Passmore Williamson_. In this case the Federal District Court held that Pa. had no jurisdiction over the right of transit. In 1860 a negress was brought from Va. to Pa. She was at once told that she was free; but when her master returned she went back with him. _Phila. Inquirer_, Aug. 29, 1860.
