Senator Thomas Hart Benton dominates the front page with an extended floor speech on the Oregon Territory dispute, delivered to Congress on May 25, 1846. Benton, a powerful voice from Missouri, is arguing fiercely against a bill that he believes goes far beyond President James K. Polk's own recommendations for extending American sovereignty over Oregon. The core of his complaint: the current bill claims too much territory and would inevitably spark hostile collisions with British agents on the other side of the Rocky Mountains. Benton proposes a careful geographical framework—dividing the disputed territory into three distinct regions (the coastal islands, Fraser's River valley, and the Columbia River valley) and arguing that America's claims rest on different grounds in each. He's particularly scathing about using maritime island discoveries to justify continental claims, a point he believes has muddied recent negotiations with Russia. Benton invokes Secretary of State John Quincy Adams's own diplomatic instructions from 1823 to prove that islands cannot grant rights to nearby continents. His message is clear: amend the bill to match the President's actual proposal, or don't pass it at all.

This speech captures America in the throes of Manifest Destiny—but with serious internal debate about how far that destiny should actually stretch. The Oregon Territory question was one of the hottest political issues of 1846, threatening war with Britain over a vast swath of the Pacific Northwest. Benton, despite his expansionist credentials, represents a faction demanding rational limits rather than unlimited territorial appetite. Just weeks after this speech, the Oregon Treaty would be negotiated, settling the boundary at the 49th parallel—remarkably close to what Benton advocated. This moment reveals that even during the height of westward expansion, American leaders were grappling with restraint, international law, and the difference between justified claims and reckless overreach.

• Benton cites David Harmon, a Vermont native, whose 19-year journal of life in the Pacific Northwest was published in 1830 and actually described Fraser's River as a British province—before America had even officially acquired it from Spain in 1819. The irony is withering: an American explorer documenting American territory as British property.
• The paper notes that the North West Company established settlements on Fraser's River starting in 1804—26 years before the U.S. acquired any claim to it from Spain. By the time America got the territory through diplomacy, the British had been operating it for over a decade.
• Benton quotes extensively from a London Quarterly Review article (reprinted in Boston in 1823) describing Fraser's River territory as having 'one-sixth of its surface' as water, with three major lakes (Stuart's, Fraser's, and McLeod's) and annual salmon runs so massive they proved connection to the Pacific Ocean.
• The publication itself is labeled as 'Volume II' of 'The Daily Union,' a tri-weekly paper that cost subscriptions prorated to annual rates—a subscriber taking it for less than a year would pay proportionally less than the yearly fee.
• Buried in procedural notes: the Senate has postponed further consideration of the Oregon bill until 'the first Monday in June'—suggesting this debate will drag on through the summer, with the nation uncertain whether it's heading toward war or negotiation with Britain.

• Benton references the 1824-1825 conventions with Russia that established the principle that island discoveries don't grant continental claims—a legal framework that would directly influence the eventual Oregon settlement two months later, which used the 49th parallel as a clean, geographical boundary.
• The Senator invokes Emperor Alexander I's 1823 proposal for 'convenience and mutual good will' in settling territorial disputes—a remarkably diplomatic note from a Russian autocrat that Benton thought should apply to the worthless volcanic islands rather than the valuable continental river valleys.
• Benton's speech is packed with references to John Quincy Adams's diplomatic instructions from 1823, cementing Adams (then Secretary of State, now a congressman) as the intellectual godfather of American territorial policy. Adams would die just three years later, in 1848, but his legal reasoning shaped westward expansion for decades.
• The paper mentions that no American or Spaniard had ever set foot on Fraser's River or its valley before 1804—yet America was now claiming it based on a Spanish title acquired in 1819. It's a reminder that 'discovery' and 'occupation' in early 19th-century diplomacy were thin justifications built on older, thinner justifications.
• Benton's willingness to cede the coastal islands to Britain (or leave them unsettled) shows that even the fiercest expansionists understood that not all territory was worth fighting for—a pragmatism that would define the final Oregon Treaty, which gave Britain Vancouver Island and the U.S. everything south of the 49th parallel.
