Mr. Webster happening to visit Trenton, N.J., to take part in a legal argument, was received by the Legislature of the State, on the 26th of March. He was welcomed in a highly eulogistic speech, to which he replied briefly, paying a high compliment to the gallant devotion of New Jersey to the cause of the country during the Revolution, and expressing his thanks for the distinguished attentions which had been shown to him. Senator Stockton, who happened to be present, spoke in terms of high admiration of Mr. Webster, commending his political course, and alluding incidentally to various topics of public interest.----Hon. JEREMIAH MORROW, a distinguished citizen of Ohio, died on the 25th of March, at the advanced age of 73. He was a member of the Territorial Legislature of Ohio in 1800, a member of the Convention to form a State Constitution in 1802, the first member of Congress from that State, afterward Senator and then Governor, serving in the latter capacity two terms, and then returning to Congress. He was a man of ability, influence, and marked integrity.----A serious accident happened in the East River, near New York, on the 26th of March. M. Maillefert, a French scientific gentleman, had been for some time engaged in blasting under water the rocks forming the whirlpool known as Hell-gate, by lowering upon the rock very heavy charges of powder, and exploding them by a galvanic battery. On this occasion, through some misunderstanding, the wrong wire was put into his hands, and he exploded a canister lying in a boat and containing sixty or seventy pounds of gunpowder. Three men were killed, and two or three others, including M. Maillefert himself, were seriously injured.----Ninety of the Americans, captured in Cuba and released by the Queen of Spain, reached New York on the 13th of March.----An extract of a private letter from Mr. Clay has been published, in which he declares his preference for Mr. Fillmore as the Whig candidate for the Presidency, on the ground that he has administered the executive government with signal success and ability. Either Gen. Scott or Mr. Webster, he says, "might possibly administer the government as well as Mr. Fillmore has done. But neither of them has been tried." Mr. Fillmore has been tried, and Mr. Clay thinks that "prudence and wisdom should restrain us from making any change without necessity."----Seven vessels of war are fitting out at New York to join the squadron in the East India seas. It is stated that in connection with other duties, Commodore Perry, the commander of this squadron, is to be instructed to make commercial arrangements with Japan, and for the better treatment of shipwrecked American sailors, who have been heretofore barbarously treated by the Japanese in several instances; and possibly may be required to make reclamations for injuries and losses heretofore sustained by American citizens. Japan has now no treaty with any Christian government except Holland.
