It is impossible not to admire the perseverance and skill with which the VanBurenites are playing their treasonable game. Not a single opportunity of making a proselyte or punishing an enemy escapes them. While at Washington Marcy and Guthrie are endeavoring to put down honest patriotism by proscription and severity, their agents here are no less active in propagating the principles which form the ground work of their party. The Post and the Daily Times are untiring in their abolition labors. The one teems with harrowing stories about runaway slaves, cruelly punished by unfeeling masters, who would not submit to be robbed; and finds a spare corner for a few well-turned compliments to Mr. Marcy's address. The other—more wily—seeks fresher material, and dilates upon the moral of the success of "Uncle Tom's Cabin" at the National; seizing the opportunity afforded by the same issue to bespatter the administration with praise. Both adore Mrs. Stowe, support Marcy, and abuse the HERALD. There is, perhaps, nothing in their course which calls for particular notice; more especially when we remember that they have all along been understood to speak the sentiments of the abolition party in this State, and that the younger of the two, started by prominent members of that party and deriving its chief support from them, is now well know to have supplanted its less adroit and more damaging ally, the Tribune, in the affections and confidence of William H. Seward. Neither the consistency with which they assail our national institutions, nor the fact of their alliance with the present cabinet, are matters of any novelty or moment. We only allude to them incidentally, lest any of our Southern readers should fancy that the administration has no friends in this city.

  We cannot, however, dismiss without a word of comment the instrument which the Times is now using to revive the abolition mania and consequently to curry favor for Marcy and the Cabinet. It is nothing less than "Uncle Tom's Cabin" in a new shape; the dramatic version which has been produced at the National. Of this performance, which we shall properly characterize by stating that it contains all the poison of the novel, with much additional trash to suit the depraved tastes of the "short boys," the Times gave an elaborate puff at its first appearance. Following up the charge in yesterday's issue, it thus comments:—

It struck pleasantly on many ears when lately we heard that the great ideas of Brotherhood, Equality, and religious responsibility in Uncle Tom's Cabin were preached to the Bowery boys from the stage. It was the more pleasant when we were assured that the mass of the audience were such as could by no inducement be beguiled into a church or religious meeting; that they were the proletaires of a great City—the wandering, marauding boy, the professional rowdy, the "flash man," and even the outcast Pariah of our society—the prostitute.

Whatever difference of opinion might be as to the correctness of the facts stated in that work, it was good to know that such an audience, with tearful eyes and enthusiastic cheers, acknowledged the grand sentiments of humanity contained in it; that the homeless boy wept to hear from Eva of her love for the poor black child, "just because she had no father, or mother, or home"; that solemn thoughts of responsibility, and even triumphant words of religious Faith, could be uttered in the Bowery, not merely without travesty and parody, but in the tones of the most appropriate feeling, to an audience still in earnest attention. It was a sermon which none of us had expected in that quarter.

  We will not stop here to point out the analogy between the language of the Times and the rant we have been used to hear from the lips of Garrison and Greeley; or speculate on the course that journal may be expected to pursue when experience shall have rendered it as hardened and as reckless as they. These are trifles in comparison with the reorganization of the abolition faction through the agency of "Uncle Tom's Cabin" in the theatre. That event, we have reason to know, is now confidently expected by the Seward and Van Buren party. The stage is expected to achieve that which the pulpit and the stump, occupied by fanatics and demagoges, have failed to accomplish. Driven from the church, the lecture room and the council chamber, W. H. Seward and his party have taken refuge in the pit of the National; it is there, among the young, the uneducated and the inexperienced, that they are sowing the seeds of future treason and disunion. Decked out with the fictitious charms of brilliant acting, gaudy scenery, gas light, and the usual attractions of a popular theatre, the treasonable sentiments expressed in "Uncle Tom's Cabin" are now being imbibed by the lowest and possibly the most dangerous class in our population. So long as the process of absorption continues Seward and his party are content; they will leave their agents to do their work; satisfied that if they can, through the instrumentality of the National Theatre and the Daily Times, convert a few boys into traitors, their time has not been lost.

  Despite the indignation which such unprincipled conduct cannot fail to arouse in every honest mind, a careful glance at the past history of the work in question is almost sure to engender a feeling of contempt and security. "Uncle Tom's Cabin" has had such a run as never book had before. Millions upon millions have been sold; translations upon translations have appeared—as many as twenty in one language; editions upon editions have been printed and disposed of; and last of all, a dozen dramatic adaptations have been played, in many of the European capitals. Here, by the influence of government hostile to republican influence; there, by the protection and favor of a titled aristocracy jealous of democratic institutions; elsewhere by the intrinsic interest of the tale it has acquired an unbounded and fabulous popularity. And yet, what has it effected? Do we find—in any European country—a state of things, a policy, even a single measure, that can clearly be traced to the effect of "Uncle Tom"? Or, looking nearer home, do we find that the million odd copies which have been scattered through the United States have added a single particle of strength to the abolition or free soil parties? Instead of this, is it not notorious that since the establishment of the Buffalo platform the abolitionist and free soil parties were never so weak as they were during the last Presidential canvass? It is a fact falling within almost every one's knowledge, that had the present administration refused to appoint free soilers to office, the party would have died in a few months, and that its present resurrection is wholly due to the manifestation of free soil tendencies on the part of Marcy and the cabinet. This does not look as though "Uncle Tom" had proved as powerful an ally for the abolitionists as people fancied. In plain truth, we take its moral effect to have been absolutely nill. It disgusted a few friends of the Union, and drew tears from a vast number of ladies, but practical consequences it has had none. It neither damaged slavery nor made treason respectable. Taking this view of the novel we do not anticipate that any very extensive mischief will be done by the play. There will be some no doubt, but it is questionable whether this will be counterbalanced by the good it will achieve in unmasking the designs of insidious traitors in our midst.
