On the 8th of June the United States Government caused the arrest of Col. W. B. Roberts, President of the Irish Republic, on a charge of conspiracy and violation of the Neutrality Act. He was brought before United States Commissioner Betts, at New York, and committed to jail pending a hearing of his case. From the quiet precincts of his contracted quarters he issued several proclamations, which teemed with gasconade and valiant promises, of which the following is a sample:

Ludlow St. Jail, New York, June 11, 1866. To the Fenian Brotherhood and
Irishmen of America:

Friends and Countrymen,—The Irish people of America are again united in the cause of Irish independence and universal freedom. The cheer which arose from the Irish soldiers at Limestone Ridge as the English foe went fleeing before their avenging steel, had found a responsive echo in every Irish heart and made us one in love, purpose and resolve. We see, after ages of your oppression, the unquenchable desire for Irish independence blaze forth anew, and as it sweeps along the cities and prairies of this vast continent it gathers within its magic influence five millions of Irish hearts and twice five millions of friends of freedom and foes of despotism! Arise, then, my countrymen! Nerve yourselves for the struggle so nobly commenced. Cast aside every consideration that would darken the bright hopes of your enslaved countrymen. Be true to liberty, your country, and your God; and your native land, instead of being a lazar-house of slavery, will soon be the garden of freedom. Stand by the cause! Be not dismayed by obstacles you meet; you must surmount them, and you will. Let cowardice and ignorance desert and denounce you—what of that? The true men are still with us, and the struggle must not be abandoned, even though our soldiers should be compelled through the over-zeal of United States officers to abandon the present campaign. There is no turning back for us, my countrymen. Our movement must and will advance. Retrogression would entail certain infamy and bring a deeper stain upon your country and race, and it is as legitimate for you to attack English power in Canada as it was for England to attack France there, or France and America England. Remember, in union there is strength, and that Union which has been cemented by the blood of our gallant brothers must be eternal, and let that man be anathemized and banned who with lying lip or evil heart would dare to weaken or dissolve it. Be true to Ireland—steadfast in the right and undismayed by obstacles, and remember that—

"Freedom's battle once begun—
Bequeathed from bleeding sire to son—
Though baffled oft, is ever won!"

I remain, with unchanged determination and regard, your countryman,

WM. R. ROBERTS, President Fenian Brotherhood.

While President Roberts was busy in penning his proclamations and exhorting his deluded followers to stand by the cause and "keep their powder dry" for a future attempt, the Revolutionary Committee of the Irish Republic were also sending out appeals to all lovers of Republican liberty, invoking further aid, from one of which circulars the following is an extract:

Let the Irish citizens in particular send in commissary stores, such as bread, meat, coffee, sugar, etc., just what each one would like at home. We want all the money you can raise for other purposes—what purposes the people can guess. Let no person imagine that the cause is defeated or that the men who have sworn to free their native land or die, will abandon their cause. A few over-zealous officials have placed some obstacles in our way. The voice of the great American people is at last heard in her halls of Congress, not from a single individual, but from the representatives of thirty, millions, and true to her natural instincts, they raise their voices for the oppressed. God bless them! They will raise many an anxious spirit through the world and make tyrants tremble on their thrones as the cry goes forth, "America is the defender of liberty." Let the people take heart throughout the land. Call meetings, pass resolutions, pledge support to the men who inscribe on their banner universal liberty. Be patient, but work! work! Collect money. Have your men ready, and when the cry of fight goes forth, let them come as individuals if they cannot come as companies or regiments.

As a large number of Fenians had gathered at Malone with very hostile intentions, Gen. Meade gave particular attention to the marauders who had mustered there. They had taken possession of the old military barracks at Malone, and were running the town to suit their own inclinations. As the days wore on and the prospects of their receiving arms and supplies to equip the invaders became more and more remote, the leaders chafed, fumed and fretted alternately, and finally became absolutely discouraged. Their fondest hopes were blasted, and they bitterly berated the United States Government in blasphemous language for stopping their expeditions. While the officers were in this frame of mind, their soldiers were worse. They were living on short rations, and their promise of a pleasant sojourn in "The Land of Plenty," where they hoped to revel in all the luxuries of life (when they captured it), was likely to prove but an empty dream. They were becoming turbulent and demonstrative, and it was finally found necessary to invoke the majesty of military power to keep them in subjection. Desertions were now frequent, and they had become a disorganized mob rather than a disciplined army. As this state of affairs was a menace to the public safety of the citizens of Malone. Gen. Meade took a firm grasp of the situation and issued the following order:

MALONE, N.Y., June 9th, 1866.
