In Massachusetts, the Hon. Charles Sumner has at length been elected to the United States Senate, for the full term of six years. He has taken no prominent part in politics, but is widely known as a scholar and philanthropist.—Soon after the decision of an exciting Fugitive Slave case in Boston, a number of citizens who had invited Mr. Webster to address them on the political condition of the country, petitioned the Board of Aldermen for the use of Faneuil Hall on that occasion. A similar petition having been previously denied to the opponents of the Fugitive Slave Law, that of the friends of Mr. Webster was not granted. The Board subsequently reconsidered their action, and passed a vote concurring with the Common Council in raising a joint committee to invite an address from Mr. Webster, and tendering the use of the Hall for the purpose. The invitation was not accepted.—A violent storm commenced on the 15th of April, and raged for more than a week along the whole extent of the Atlantic coast. During the night of the 17th, the light-house on Minot's Ledge, near Cohasset, was swept away; two assistant keepers who were in the structure were lost.—The secret-ballot law has passed both branches of the Legislature. It provides that the ballots of voters shall be inclosed in envelopes previously to being deposited in the ballot boxes.

In Connecticut there was no choice by the people of State officers at the late election. Hon. Thomas H. Seymour, the Democratic candidate, has been re-elected as Governor by the Legislature. The Democratic candidates for Secretary and Comptroller, and the Whig candidates for Lieutenant-Governor and Treasurer, were elected by the Legislature. In his Message the Governor represents the finances of the State to be in a prosperous condition; recommends the passage of general corporation and banking laws; and of a law limiting the hours of labor, to contain a provision making it a misdemeanor to work children under fourteen years of age more than eight hours a day. He speaks in favor of the Compromise measures, which he says must be supported in good faith, or we can not hope to see this form of Government continue. "Whatever action then," he adds, "the Legislature may feel called upon to take, upon any of the questions to which reference has been made, I feel at liberty to indulge the hope that its course will be such as to place the State of Connecticut on patriotic and dignified ground in the presence of sister States and the nation, and the world."

A Convention of the Southern Rights Association assembled at Charleston, May 5. There were between three and four hundred members in attendance. Ex-Governor J.P. Richardson acted as President. In his address upon taking the chair, he said that the question was simply as to the time and manner of resistance. He spoke strongly of the want of affinity between the two sections of the country, and declared that no one should join together those whom God and nature have put asunder. A letter from Hon. Langdon Cheves was read, deprecating separate action on the part of South Carolina, which ought to wait awhile longer for the action of other States. An address and resolutions advocating the right and expediency of secession, were adopted. Mr. Rhett, one of the United States Senators from this State, has developed what he supposes to be the results of the policy of secession. Free trade would be proclaimed with all States south and west of the Potomac, and a duty of ten per cent. levied upon goods from the other States and from foreign countries. The result would be that goods would be twenty per cent. cheaper in Charleston than in New York. The trade of Georgia and North Carolina would be carried on with South Carolina; and it would not be in the power of the General Government to prevent it, by a line of custom-houses along the frontier. He declared the idea of a blockade of the ports of South Carolina to be ridiculous. Blockade was war, and Congress alone could declare war; and Congress must either let them go peaceably out of the Union or fight; and fight they would in defense of their rights, liberties, and institutions; and even if South Carolina should be subdued, the Union was not preserved; other Southern States would join in the contest. Should that State secede and remain for five years an independent State, a Southern Confederacy must be the result, or the South would have enforced the guarantees to which she is entitled. "I have been battling," he says, "in this cause for twenty-five years, and have now but a few more years to give to your service. As a citizen of South Carolina, I demand that she make me free. My counsel is, secede from the union of these United States. At every hazard, and to the last extremity secede. If I was about to draw my last breath, with that breath I would exhort you to secede."

In the Virginia Constitutional Convention some votes have been taken, which afford indications that the mixed basis proposition in a somewhat modified form, will prevail. The motion to strike out the proposition apportioning representation on the basis of the white population was carried by a vote of 65 to 56. Four Eastern men, among whom was Hon. Henry A. Wise, voted with the West. One of the mixed basis propositions failed by a single vote.

From the mining region of Lake Superior, the latest intelligence is highly favorable; large quantities of copper are preparing for market.—The President has directed that the lands occupied by the Hungarian Exiles in Iowa shall not be offered for sale previous to the meeting of Congress, when a petition will be presented for the grant of them to the exiles.—A riot occurred lately at Milwaukie upon occasion of a lecture upon Catholicism by Mr. Leahy, who claims to have once been a Trappist monk. More than a score of persons were seriously injured, and considerable damage was done to the Methodist church in which the lecture was given. The principal Catholic laity and the clergy published a card in which they express their unqualified condemnation of the conduct of the rioters, and engage to make good the pecuniary injury inflicted.—The Central Railroad of Michigan has for some time been annoyed by a gang, which has at length been brought to light. Their detection was effected by an agent of the Railroad, who in order to secure their confidence undertook to set fire to the dépôt; after, however, taking precautions to prevent any serious injury. Nearly fifty persons have been arrested and indicted; among whom are a judge, justices of the peace, constables, and professional men. The trial will come on in June.—The Legislature of Wisconsin have passed a bill for the protection of Seventh Day Baptists. It provides that any civil process issued against a person who habitually observes the seventh day as a day of rest, which is made returnable on that day, may be laid over until the Monday following, as though that were the return-day of the writ.—The small pox is raging with fearful violence among the Sioux Indians upon the Upper Missouri. It is also extending down the river, among the Sacs and Foxes. Several hundred are reported to have already died.

The Governor of Texas has issued an order for the arrest of the members of the Boundary Commission who took part in the recent summary executions of the desperadoes at Socorro. They are probably beyond the jurisdiction of Texas. Severe charges are in circulation against the officers at the head of the Commission; public opinion will, however, remain undecided until both sides are heard.—The population of New Mexico, according to the recent census, is 61,574, of whom 850 are Americans. Of the Mexican population above the age of twenty, only one in 103 is able to read.—A treaty has been concluded with the Apache Chief Chacon, who binds himself to keep the peace, under penalty of forfeiting his life.—An attempt is to be made to diminish the enormous expense of the military occupation of New Mexico. Colonel Sumner, the new commander, will take out with him seed, grains, stock, and farming utensils, and every effort will be made to develop the agricultural resources of the Territory. The head-quarters of the army will probably be removed from Santa Fé to Los Vegos.

From California the most striking feature of intelligence is the unexampled frequency of extra-judicial punishment for crime. The newspapers are filled with accounts of summary executions, not only for murder but for robbery and theft. Under the peculiar state of things occasioned by the great temptations to crime, and the utter want of all the ordinary apparatus of justice, during the earlier periods of the settlement of California, this was unavoidable. But instances of this sort, instead of becoming more unfrequent, seem to be rapidly increasing. A bill has passed the Legislature, and become a law, inflicting the punishment of death, at the discretion of the jury, upon the crime of grand larceny. This measure was insisted upon by the mining counties on the ground that, owing to the unexampled influx of desperadoes and criminals from all parts of the world, thefts and robberies had become so frequent, while prisons and places of detention were so few, that the only possible punishment was death; and the people had become so exasperated that the punishment would and must be inflicted, either by or against the law. The law imposing a tax upon foreign miners has been repealed, having been found to work most disastrously. It drove out of the country many thousands of the most industrious miners, especially Mexicans and Chilians, whose labors the State could ill spare. Indian hostilities have nearly ceased. A number of the tribes have signified a willingness to accept of fixed localities, and to enter into a treaty. The Legislature having granted to the Governor authority to call out 500 men to repress Indian hostilities in the Mariposa region, he made a tour of inspection, and came to the conclusion that the force was unnecessary. The population of the State is estimated at 314,000, of whom about 100,000 are supposed to be engaged in mining; and the whole amount of gold produced in the course of last year is estimated at about one hundred millions of dollars, giving about three and one-third dollars a day to each individual. It is anticipated that the amount produced the ensuing year will not fall short of one hundred and fifty millions. The recent accounts of the lately discovered gold bluffs are encouraging, and promise a large amount of gold from that source. A mine of quicksilver, stated to be the richest in the world, has been discovered about twelve miles from San José. In the case of a slave brought into the State by his master, it has been decided that he can not be removed against his will. A vessel has arrived at San Francisco having on board seventeen Japanese, who were picked up at sea from a wreck. It is supposed that they will be conveyed to their native country in a government vessel. They are thought to be the first Japanese who have ever set foot upon the American continent. A rich coal mine is stated to have been discovered about eight miles from Benicia. The quantity of land under cultivation has greatly increased. Professor Forrest Shepard, of New Haven, has made some remarkable discoveries of thermal action. In one place, where there was nothing on the surface to excite attention, on digging down the heat increased so rapidly that at the depth of two feet he could not bear his hand in the earth, and the thermometer indicated a temperature of 130 degrees. At another place, after wandering for four days through dense thickets, he came upon a chasm a thousand feet deep, through which followed a stream, the banks of which, on the 8th of February, were covered with vegetation. Following up the stream, the earth grew so hot as to burn the feet through the boots. There was no appearance of lava, and the rocks were being dissolved by a powerful catalytic action. From innumerable orifices steam was forced to the height of two hundred feet. The number of spouting geysers and boiling springs, on a half mile square, exceeded two hundred. The Professor, in the course of a lecture on the mineral resources of California, delivered in the Senate Chamber at San José, said that he did not doubt that silver, lead, and iron abounded in California.

SOUTHERN AMERICA.

In Mexico the finances are in a most deplorable condition. The revenue had fallen to about eight and a half millions of dollars, while the expenses exceed twelve millions. The indemnity paid by our government can afford only temporary relief in the face of so alarming a deficiency. The Minister of Finance has resigned his post, and has prepared a memoir on the condition of the department. The Government has made a formal complaint against that of the United States for failure in carrying out the provisions of the treaty in relation to the suppression of Indian depredations on the frontier; and assigns this failure as a ground for refusing to ratify the Tehuantepec treaty. The Commissioners of Public Works have been directed to ascertain the names, employment, and places of nativity of foreigners residing in the city. Several projects for a change of government are entertained. One party are desirous of returning to the dominion of Spain; another is in favor of annexation to the United States; the return of Santa Anna is desired by another. The Northern States are still harassed by Indian depredations. The hostilities in Yucatan are supposed to be nearly at an end. The municipality of the capital have petitioned for the suppression of bull-fights throughout the state.

Hostilities are brooding between Brazil and the Argentine Republic; but it is hoped that war may be averted. The dissentions in the latter state are favorable to the recognition of the claims of Brazil. Government is endeavoring to suppress the slave-trade, and its efforts meet with some success.
