At this time there was much written about the States bordering upon and beyond the Mississippi River. The Kansas excitement was at its height and there was a general desire to "go west." Following this popular feeling, Henry Horthup, at the close of the school year in 1860, and against the desire of those connected with the University, resigned his position and pushed on to the State of Missouri. It was his expectation to obtain a position in some institution of learning, but he soon fund that the Normal teachers from the free State of Massachusetts, were not wanted at that time within the borders of that State, and he was compelled to seek the more congenial atmosphere of Iowa. Here he engaged in teaching, during the winter of 1860-61, in the town of Anamosa, and here he began the study of law, borrowing a "Blackstone" from the office of a lawyer friend, and spending his time in the office on Saturdays. In April, 1861, at the close of the school year, he went to Dubuque, to engage as teacher in one of the public schools of that city.

Henry entered the ranks; became a member of the First Iowa Infantry, and in a few weeks, under the leadership of General Lyon, was again in Missouri, making the campaign of 1861 in that State, ending in the battle of Wilson's Creek, the death of General Lyon and the retreat of the Federal forces on Rolla.

The period of enlistment of the First Iowa having expired, Mr. Northup returned to his Eastern home. Teaching a private school in the winter of 1861-62, in his native town, in the spring of the latter year, he again entered the army, having obtained the reluctant consent of his mother, remaining until the fall of 1863, when he resumed teaching and desultory reading of the law.

In March, 1865, he was appointed to a clerkship in the Government service at Washington, and here, while attending to the duties of his position, resumed his legal studies, graduating from the Columbia College Law School in June, 1868, and being soon after admitted to the bar in the Supreme Court of the District of Columbia.

In May, 1871, Mr. Northup resigned his position at Washington and removed to Portland, Oregon, where he entered upon the practice of the law. Two years later a vacancy occurred in the office of Register of Bankruptcy for the District of Oregon, and he was appointed to that position, and satisfactorily performed the duties of the office until the repeal of the bankrupt law in 1878. Since then he had been engaged in a general practice, giving much attention to real estate and corporations. He was associated in business with Judge E. C. Bronaugh and the firm of an extensive practice.

Mr. Northup's legislative career was a very active one and met the approbation of his constituents. He was the introducer of the pilot bill, a measure intended to correct the abuses in the pilotage system on the Columbia and Willamette Rivers; also of the Soldiers' Relief Bill, and had charge of the Consolidated Charter Bill for the consolidation of the cities of Portland, East Portland and Albina, a measure which passed the assembly but failed to become a law by reason of the Governor's veto. He also took an active part in the discussion on the "Portland Water Bill" and the bill to regulate the shipping of seamen.
