The significance of this little volume lies in the fact that through it the country destined to give birth to "the only free child of the Missouri Compromise" was christened IOWA. Lieutenant Lea was familiar with the country described in his "Notes." He had traveled through it, had seen its beautiful prairies, had met its inhabitants face to face, and had enjoyed their frontier hospitality. He must have been deeply impressed by the Iowa river and its name. Referring to the country west of the Mississippi river he says: "The District under review has been often called 'Scott's Purchase,' and it is sometimes called the 'Black-Hawk Purchase'; but from the extent and beauty of the Iowa river which runs centrally through the District, and gives character to most of it, the name of that stream, being both euphonous and appropriate, has been given to the District itself." The Iowa District was likely to become a separate Territory at an early day, since all indications pointed in the direction of a division of the Territory of Wisconsin. First, the geographical area of the Territory as designated in the Organic Act was sufficient for three or four ordinary Commonwealths. Secondly, this area did not possess geographical unity. Thirdly, historical traditions and considerations favored the establishment of a separate Territory east of the Mississippi, which at the proper time should be admitted as the fifth State born of the Ordinance of 1787 within the limits of the old Territory of the Northwest. Fourthly, the population of the Territory, which was increasing with unparalleled rapidity, was so widely scattered as to make it practically impossible to give equal force to the laws and equal efficiency to the administration of government in all of the frontier communities. That the "Father of Waters" should serve as the natural line of division was generally conceded. Scarcely had the act organizing the Territory of Wisconsin gone into effect, when the agitation for division was launched. By the fall of 1837 it had captured the public mind. The burden of the movement was taken up with enthusiasm by the inhabitants of the Iowa District. They realized that the proposition to remove the seat of the Territorial government from Burlington to some point east of the Mississippi was likely to rob them of much political influence and some distinction. They felt that a Territorial government located somewhere "in the vicinity of the Four Lakes" could not successfully administer constitutional government in the Iowa District.
