In consequence of various rumors which prevailed in the City of Savannah, concerning the invasion of Cuba, the United States Marshal chartered a steamboat for an exploring trip to the South. He proceeded as far as Jacksonville, Florida, and returned after a cruise of three or four days. Throughout the whole line of his route, he was met with accounts of encampments of armed men, but they proved to be without foundation, and no discoveries, pointing to any overt acts, were made. It was the general belief, among all with whom he conversed, that a movement of importance had been projected against the island of Cuba, but that from causes which have not transpired, the organization had been broken up, and the men connected with it had entirely dispersed. Between Savannah and Jacksonville, public opinion was found to be decidedly favorable to the expedition, the great majority of the people sympathizing with the Cubans, and ready to aid them in a struggle for independence. The session of the Legislature of New York came to a sudden and unexpected close on the 17th of April, two days after the conclusion of our last Monthly Record.

They bring severe charges against their opponents of mal-administration of the financial affairs of the State; and denounce the proposed measure as a palpable violation of the express provisions of the Constitution, and as an expedient to secure to their opponents the political supremacy in the State. The Whig members also issued a long address to the People of the State of New York, in which they denounce the conduct of the resigning Senators as a willful violation of the Constitution which they had sworn to support and as an outrage upon the fundamental principle of a republican government--the right of the majority to rule. They defend the course of adjournment adopted by the majority, on the ground that two-fifths of the State was unrepresented in the Senate; that for various important purposes for which the assent of two-thirds of the
