June 29th. It is generally believed by the prisoners that we have badly whipped the Yankees before Richmond. Yankee newspapers try to conceal it, but their conflicting accounts of battles betray their efforts to pervert the truth. May it be so, and if so, Deo Gratias! The Yankee officers here say that General McClellan is certainly on “Church Hill.”

June 30th. The editor of the “Baltimore American” has been arrested, it is said, for publishing the accounts of the battles before Richmond too soon. Having met with the subjoined address, I record it as a part of the current history of the times:

Address of the Democratic Members of Congress to the Democracy of the United States.

Fellow-Citizens:—The perilous condition of our country demands that we should reason together. Party organization, restricted within proper limits, is a positive good, and indeed essential to the preservation of public liberty. Without it the best government would soon degenerate into the worst of tyrannies. In despotisms the chief use of power is in crushing out party opposition. In our country the experience of the past twelve months proves, more than any lesson in history, the necessity of party organization. The present administration was chosen by a party, and in all civil acts and appointments has recognized, and still does, its fealty and obligations to that party. There must and will be an opposition. The public safety and good demand it. The Democratic party was founded more than sixty years ago. It has never been disbanded. To-day it numbers one million five hundred thousand electors in the States still loyal to the Union. Its recent numerous victories in municipal elections in the Western and Middle States proves its vitality. Within the last ten months it has held State Conventions, and nominated full Democratic tickets in every free State in the Union. Of no other party opposed to the Republicans can the same be said. Shall the Democratic party be now disbanded? Why should it? Are its ancient principles wrong? What are they? Let its platforms for thirty years speak:

Resolved, That the American Democracy place their trust in the intelligence, the patriotism, and the discriminating justice of the American people, That we regard this as a distinctive feature in our political creed, which we are proud to maintain before the world, as the great moral element in a form of government, springing from and upheld by the popular will; and we contrast it with the creed and practice of Federalism, under whatever name and form which seeks to palsy the will of the constituent, and which conceives no imposture too monstrous for the public credulity. That the Federal Government is one of limited power, derived solely from the constitution, and the grants of power made therein ought to be strictly construed by all the departments and agents of the government; and that it is inexpedient and dangerous to exercise doubtful constitutional powers.”

And as explanatory of these the following from Mr. Jefferson’s inaugural: “The support of the State Governments in all their rights as the most complete administration of our domestic concerns, and the surest bulwarks against anti-Republican tendencies. The preservation of the General Government in its whole constitutional vigor, as the sheet anchor of our peace at home and safety abroad.” Such, Democrats, are the principles of your party, essential to public liberty, and to the stability and wise administration of the government, alike in peace and war. They are the principles upon which the Constitution and Union were founded; and under the control of a party which adheres to them, the constitution would be maintained, and the Union could not be dissolved.

This morning Lieutenant Holmes (one of the Yankee officers) came up to our room and enquired “who has been talking to a man outside through the bars?” “No one in this room,” was the reply, when he went out, looking as if he believed we were falsifying. Soon Lieutenant Holmes, or “Mullet-head,” as the “boys” call him, returned and said, “I have the culprit.” The gentleman on the street to whom the prisoner was talking was arrested, and the prisoner himself put in solitary confinement. Some two weeks ago two little girls were arrested for waving their handkerchiefs to prisoners, and a little child who could not speak plainly for saying “Hoowaugh for Bowaygard.”

July 2d. A little girl, 12 years of age, was arrested to-day for wearing an apron like the Confederate Dag. The surgeon of this prison is known as “Cyclops” among us. A week ago “Cyclops” said “our forces are about now in Richmond—the Anaconda is gradually coiling around the last vital point of the rebellious monster.” What does he think now? The “New York Times” acknowledges the loss of upwards of twenty pieces of artillery in one fight. The Yankee papers a week ago reported General Thomas C. Hindman, of Arkansas, as certainly dead.

In yesterday’s paper is the following telegram:—“Advices from Arkansas are to the effect that General Hindman, with some five thousand rebels was in the immediate vicinity of the St. Charles,” and that Colonel Fitch had abandoned the forts, spiking the guns. The situation of General Curtis is said to be critical, he being unable to obtain supplies, and his army having been on half rations for a week:

THE FATE OF RICHMOND.

We expected to have been able to announce in our yesterday afternoon’s edition the important fact that Richmond was, in possession of General McClellan’s army. From sources of information which we deemed trustworthy, we, however, believe that the fact was known in this city yesterday afternoon, and also communicated by the authorities here to Washington, but for reasons no doubt satisfactory, an official recognition of the fact was withheld by the War Department. Our theory of the case is this: Although the city is in our power or possession, yet the Rebel army is still in arms, but is so situated that it can neither escape from the coils of the anaconda with which McClellan enfolds it, nor has it the means of obtaining supplies; neither can it attack our forces, who hold the possession of the bridges over the Chickahominy, which are controlled by our heavy artillery, and there is no other means of access to McMillan, it being impossible for the Rebels to get through the marshes adjacent to the river. The result must be that the Rebels must surrender or starve, as they can neither fight or skedaddle. They are in a fix.

This, as before remarked, is our theory of the matter, and the government withholds the official intelligence of the taking of Richmond, until it can accompany it with the additional gratifying announcement, which probably they may be able to make in time to send to England by the steamer which sails to-day, of the capture not only of Richmond, but of the entire Rebel army. For giving this opinion, we hope we may not be called upon to keep our neighbor company at Fort McHenry.—Baltimore Clipper, July 2.

July 3d. Parson Brownlow, of Tennessee, delivered a speech last night at Ford’s Atheneum, in this city, to a large audience. The meeting closed with lusty cheers for the Parson, State of Tennessee, and the Union:
