Finally, all complications were dispersed, and the treaty ratified; and then came an attack from an unexpected quarter.

General Cass--our minister at Paris--undertook to protest against the treaty, denounce it, and leave his post on account of it.

This wholly gratuitous assault led to a public correspondence, in which General Cass, on his own confession, was completely overthrown and broken down by the Secretary of State.

This was the last difficulty, and the work was finally accepted and complete.
During this important and absorbing negotiation, other matters of less moment, but still of considerable consequence, had been met by Mr.Webster, and successfully disposed of.

He made a treaty with Portugal, respecting duties on wines; he carried on a long correspondence with our minister to Mexico in relation to certain American prisoners; he vindicated the course of the United States in regard to the independence of Texas, teaching M.de Bocanegra, the Mexican Secretary of State, a lesson as to the duties of neutrality, and administering a severe reproof to that gentleman for imputing bad faith to the United States; he conducted the correspondence, and directed the policy of the government in regard to the troubles in Rhode Island; he made an effort to settle the Oregon boundary; and, finally, he set on foot the Chinese mission, which, after being offered to Mr.Everett, was accepted by Mr.Cushing with the best results.
