Historical Review of the Month.

In the United States, since our last publication, no events have occupied more attention than the great Agricultural State Fair which was held recently at Rochester, and of which we shall give a particular account, illustrated with numerous engravings, in our next number; and the Railroad Festival at Boston, which was held at the same time. At the latter were present the President of the United States, the Secretary of State, and other members of the Cabinet, the Governor-General of Canada, his Aids and Cabinet, the principal members of the Canadian Parliament, and the leading merchants in the Canadian cities, the Governors of New England states, the Presidents of the railways in New England, the Mayors of the cities of New England and many other influential persons interested in railways and steam navigation. Speeches were made by the President of the United States, by Lord Elgin, Daniel Webster, Edward Everett, and many others, and the occasion was altogether one of the most brilliant and satisfactory of its kind ever known in this country.

On the 10th of September Mr. Gorsuch, a citizen of Maryland, accompanied by several officers and other persons, proceeded from Philadelphia to Christiana, near Lancaster, for the purpose of arresting two negroes claimed under a law of the United States as fugitive slaves. In order to resist the execution of the law the negroes of the vicinity rallied to the number of seventy or eighty, armed themselves with guns, and fired on the party of whites, killing Mr. Gorsuch, and mortally wounding his son. The negroes were also considerably injured by a discharge from revolvers by the party with the officers. It appears from a statement published by the Rev. Mr. Gorsuch, a son of the claimant of the negroes, that a conspiracy was planned beforehand, to resist the officers of the law in the execution of their duty; and that it was not confined to the negroes, but was apparently under the guidance and control of whites. Mr. Gorsuch says that while the officers were awaiting the decision of the blacks, a white man rode up; that his presence seemed to inspire the negroes with renewed hostility; that he refused, when summoned, to aid the officers, and threatened them with bloodshed if they persisted in executing the law. It is further alleged that it was after receiving some communication from this person that the negroes rushed on the officers and killed Mr. Gorsuch. Since then a correspondence on the subject has been held between the national executive and the executives of the states of Maryland and Pennsylvania. The slaves have not been recovered, but many arrests have been made of persons charged with conspiracy to prevent the execution of the laws, and with treason.

The Free Soil party of Massachusetts, at a State Convention, held Sept. 16, nominated for Governor, John G. Palfrey, and for Lieutenant-Governor, Amasa Walker. The nomination for Governor was first tendered to Stephen C. Phillips, of Salem, who declined. The democrats held their State Convention on the 26th of August. They passed resolutions decidedly in favor of the Union, and against all anti-national and anti-sectional agitation. George S. Boutwell was nominated for Governor, and Henry W. Cushman for Lieutenant-Governor, and Charles G. Greene, Henry H. Childs, and Isaac Davis, were appointed delegates to the National Democratic Convention, which was recommended to be holden at Baltimore in May, 1852. The Whig State Convention was held at Springfield on the 10th of September and, on the first ballot, Robert C. Winthrop was nominated as their candidate for Governor, and George Grinnell as their candidate for Lieutenant-Governor. The proceedings were very harmonious, and the address of the chairman, and the resolutions passed by the convention, were of a strong national and Union character. Edward Everett, George Ashmun, and Seth Sprague, were chosen delegates from the State at large to the National Whig Convention.

In New-York the Whig State Convention assembled at Syracuse on the 11th of September. George W. Patterson, was nominated for Controller; James M. Cook, for Treasurer; Samuel A. Foote, for Judge of the Court of Appeals; James C. Forsyth, for Secretary of State; Daniel Ullmann, Jr., for Attorney-General; Henry Fitzhugh, for Canal Commissioner; and A. H. Wells, for State Prison Inspector. Resolutions were adopted, declaring that the proceeding of the two Whig State Committees at Albany, for the union and co-operation of the party, was "the result of honorable and patriotic devotion to the Constitution, and for the best interests of the whole people, and that it is adopted and approved by this Convention;" and pledging the whigs to the most liberal conduct in the matter of internal improvements. The Democratic Convention met at the same place on the tenth. Resolutions were adopted reaffirming the principles avowed in the resolutions adopted by the State Convention held at the same place last year. The following persons were nominated for the several state offices: John C. Wright, for Controller; Henry S. Randall, for Secretary of State; Levi S. Chatfield, for Attorney-General; Benjamin Welch, Jr., for Treasurer; Horace Wheaton, for Canal Commissioner; W. J. M'Alpine, for State Engineer; General Storms, for Inspector of State Prisons; and A. S. Johnson, for Judge of the Court of Appeals.

The Maryland Whig State Convention at Baltimore, September 17th, nominated, with great unanimity, the following State ticket: For Controller of the Treasury, George C. Morgan; Lottery Commissioner, O. H. Hicks; Commissioner of the Land Office, George C. Brewer. The Democrats, at their State Convention held at Baltimore, on the 12th, nominated Philip Francis Thomas, of Baltimore City, for Controller; James Murray, of Annapolis, for Commissioner of the Land Office; Thomas R. Stewart, of Caroline, for Lottery Commissioner.

In Virginia, an election for members of Congress, under the old system and apportionment, takes place on the fourth Thursday in the present month. The question of the ratification of the new constitution is to be decided under the universal suffrage system, on the same day. Members of the Legislature are also to be elected, according to the old apportionment; but if the new constitution is ratified, the legislative election is to be superseded by a new election, under the new apportionment, in December next. At the same time, a Governor and Lieutenant-Governor &c., are to be elected; and next spring, the county officers will be chosen in another election; after which the State elections will occur regularly from time to time.

In South Carolina a large meeting was held at Charleston, on the 28th of August, in favor of co-operation between the slaveholding states, and opposed to separate State Action for the purpose of resistance to the National Government. John Rutledge presided, and in the list of other officers we find the names of many of the most distinguished citizens of the State. Our advices from California, to the 14th of August, are of a favorable character. In San Francisco business is active in spite of the effects of the recent conflagration, and the administration of justice is placed on a more substantial basis. Great activity prevails in the mining districts, and the work of constructing canals on various gold-bearing streams is vigorously advancing. Accounts from Utah represent the new territory in a prosperous condition, with the exception of some slight Indian difficulties. The crops are unusually fine. The emigrants for Salt Lake and Oregon are progressing prosperously. The Mormons have extended their settlements along the base of the mountains, northward, and facing the Great Salt Lake, ninety miles, nearly to Bear River ferry. They are fast taking up all the good land in the Valley, and are engaged in building a railroad to the mountain, some seven or eight miles, on which to transport the materials for their great temple. Dr. John M. Bernhisel has been chosen Territorial Delegate to Congress.
