To this plea in abatement, a demurrer having been interposed on behalf of the plaintiff, it was sustained by the court. After the decision sustaining the demurrer, the defendant, in pursuance of a previous agreement between counsel, and with the leave of the court, pleaded in bar of the action: _1st, not guilty; 2dly, that the plaintiff was a negro slave, the lawful property of the defendant, and as such the defendant gently laid his hands upon him, and thereby had only restrained him, as the defendant had a right to do; 3dly, that with respect to the wife and daughters of the plaintiff, in the second and third counts of the declaration mentioned, the defendant had, as to them, only acted at the same manner, and in virtue of the same legal right_. Issues having been joined upon the above pleas in bar, the following statement, comprising all the evidence in the cause, was agreed upon and signed by the counsel of the respective parties, viz: "In the year 1834, the plaintiff was a negro slave belonging to Doctor Emerson, who was a surgeon in the army of the United States. In that year, 1834, said Dr. Emerson took the plaintiff from the State of Missouri to the military post at Rock Island, in the State of Illinois, and held him there as a slave until the month of April or May, 1836. At the time last mentioned, said Dr. Emerson removed the plaintiff from said military post at Rock Island to the military post at Fort Snelling, situate on the west bank of the Mississippi river, in the Territory known as Upper Louisiana, acquired by the United States of France, and situate north of the latitude of thirty-six degrees thirty minutes north, and north of the State of Missouri. Said Dr. Emerson held the plaintiff in slavery at said Fort Snelling, from said last-mentioned date until the year 1838. "In the year 1835, Harriet, who is named in the second count of the plaintiff's declaration, was the negro slave of Major Taliaferro, who belonged to the army of the United States. In that year, 1835, said Major Taliaferro took said Harriet to said Fort Snelling, a military post situated as hereinbefore stated, and kept her there as a slave until the year 1836, and then sold and delivered her as a slave at said Fort Snelling unto the said Dr. Emerson, hereinbefore named. Said Dr. Emerson held said Harriet in slavery at said Fort Snelling until the year 1838. "In the year 1836, the plaintiff and said Harriet, at said Fort Snelling, with the consent of said Dr. Emerson, who then claimed to be their master and owner, intermarried, and took each other for husband and wife. Eliza and Lizzie, named in the third count of the plaintiff's declaration, are the fruit of that marriage. Eliza is about fourteen years old, and was born on board the steamboat Gipsey, north of the north line of the State of Missouri, and upon the river Mississippi. Lizzie is about seven years old, and was born in the State of Missouri, at a military post called Jefferson barracks.
