The American flag was elevated above the roof of the University at New York, by Captain Jones, late of Harper's Ferry, amid the enthusiastic cheers of a large collection of people. Dr. Bethune made some remarks, taking occasion to make a fitting allusion to Major Anderson and Fort Sumter, which were received with repeated and enthusiastic cheering. Ile had looked over ancient history for a parallel to this deed of valor, but found none. The bravery shown by the three hundred Spartans at the Pass of Thermopyle was well known; but there still was one coward among them. There was no coward among the men at Sumter. He had been present at a conversation with the gallant defender of the fort, when a gentleman remarked he regretted that the major had not blown up the fort, to which Major Anderson replied that it was better as it was. The ruined battlements and battle-scarred walls  of Fort Sumter would be an everlasting shame and disgrace to the South Carolinians. At the conclusion of Dr. Bethune's remarks the “Starspangled Banner” was sung, all the audience rising to their feet and joining in the chorus. Col. Baker and Capt. Jones also made short addresses.--The World, May 4.
Governor Letcher published a proclamation, saying that the sovereignty of the Commonwealth of Virginia having been denied, her territorial rights assailed, her soil threatened with invasion by the authorities of Washington, and every artifice employed which could inflame the people of the Northern States against her, it therefore becomes the solemn duty of every citizen of Virginia to prepare for the impending conflict. To this end, and for these purposes, and with a determination to repel invasion, Governor Letcher authorizes the Commanding General of the military forces to call out, and cause to be mustered into service from time to time, as the public exigencies may require, such additional number of volunteers as he may deem necessary.--(Doc. 129.)

Union Ward meetings were held to-night throughout Baltimore, Md., and resolutions were adopted to the following purport:-- That we cherish the Constitution and laws of the United States, and will devote our fortunes and lives to defend their integrity against all revolutionary or violent assaults; that we regret the violent attacks on the troops of the United States while peacefully marching through the city to protect the seat of Government, and indignantly repudiate making it a pretext to organize an armed mob, under the guise of a special police, to place the city in a hostile attitude to the General Government; declaring abhorrence at the attempt of the Legislature to inaugurate a military despotism by the bill for the creation of a Board of Public Safety; that the persons named for said Board have not the confidence of the people, and we protest against the whole measure as an invasion on the prerogatives of the Governor and a usurpation of the Executive power by the Legislature.--N. Y. Tribune, May 4.

Governor Jackson of Missouri, in a message to the legislature of that State, says the President of the United States in calling out the troops to subdue the seceded States, has threatened civil war, and his act is unconstitutional and illegal, and tending towards consolidated despotism. While he evidently justifies the action of the Confederate States in seceding, he does not recommend immediate secession, but holds the following language:
Our interest and sympathies are identical with those of the slaveholding States, and necessarily unite our destiny with theirs. The similarity of our social and political institutions, our industrial interests, our sympathies, habits, and tastes, our common origin, territorial contiguity, all concur in pointing out our duty in regard to the separation now taking place between the States of the old federal Union.He  further adds that “Missouri has at this time no war to prosecute. It is not her policy to make an aggression; but, in the present state of the country, she would be faithless to her honor, recreant to her duty, were she to hesitate a moment in making the most ample preparation for the protection of her people against the aggression of all assailants. I therefore recommend an appropriation of a sufficient sum of money to place the State at the earliest practicable moment in a complete state of defence.” In conclusion he says: “Permit me to appeal to you and through you to the whole people of the State, to whom we are all responsible, to do nothing imprudent or precipitate. We have a most solemn duty to perform. Let us then calmly reason one with another, avoid all passion and tendency to tumult and disorder, obey implicitly the constituted authorities, and endeavor ultimately to unite all our citizens in a cordial cooperation for the preservation of our honor, the security of our property, and the performance of all those high duties imposed upon us by our obligations to our families, our country, and our God.” --Louisville Journal, May 4.
