Lines of Longitude is the answer
Answer: Because they found a compromise and agreed on the principle.
Explanation:
The tariff of 1833 itself is also known as the Compromise Tariff. The tax was proposed by Henry Clay and John C. Calhoun and supported by President Andrew Jackson. An agreement was reached because a solution was found that everyone thought was best. These tariffs reduced the rate passed a year earlier because of the Southerners' objection to protectionism contained in the 1832 tax. The controversial issues surrounding the "Tariff of Abominations", as many have called it, were resolved in 1828, after which South Carolina threatened secession. The tariff also guaranteed a gradual tax cut over the next ten years.
