"Sec. 7. And whereas doubts have arisen whether the time of service of negroes and mulattoes, bound to service in this territory, may be sold on execution against the master, _Be it therefore enacted_ that the time of service of such negroes or mulattoes may be sold on execution against the master, in the same manner as personal estate, immediately from which sale the said negroes or mulattoes shall serve the purchaser or purchasers for the residue of their time of service; and the said purchasers and negroes and mulattoes shall have the same remedies against each other as by the laws of the territory are mutually given them in the several cases therein mentioned, and the purchasers shall be obliged to fulfil to the said servants the contracts they made with the masters, as expressed in the indenture or agreement of servitude, and shall, for want of such contract, be obliged to give him or them their freedom due at the end of the time of service, as expressed in the second section of the law of the territory, entitled 'Law concerning servants,' adopted the twenty-second day of September, eighteen hundred and three. This act shall commence and be in force from and after the first day of February next."[47] This was bold legislation; but it was not all. Negroes were required to carry passes, as in the slave States. And on the 17th of September, 1807, "_An Act for the Introduction of Negroes and Mulattoes into_" the territory was passed. "Sec. 1. That it shall and may be lawful for any person being the owner or possessor of any negroes or mulattoes of and above the age of fifteen years, and owning service and labor as slaves in any of the States or territories of the United States, or for any citizens of the said States or territories purchasing the same to bring the said negroes and mulattoes into this territory. "Sec. 2. The owners or possessors of any negroes or mulattoes as aforesaid, and bringing the same into this territory, shall, within thirty days after such removal, go with the same before the clerk of Court of Common Pleas of proper county, and in presence of said clerk the said owner or possessor shall determine and agree to, and with his or her negro or mulatto, upon the term of years which the said negro or mulatto will and shall serve his or her said owner or possessor, and the clerk shall make a record.
