In submitting for your approbation and support, the designation contained in the proceedings of a meeting of the Republican Delegation from the Middle District, herewith published, we take the liberty of addressing a word to you on the important subject to which it relates. In doing so, it can scarcely be necessary to state to you, that the right exercised by us on the present occasion, is founded, and founded only, in a usage hitherto acquesced in by the party to which we are proud to acknowledge ourselves attached—a usage, however, the existence of which has been coeval with the prosperity of that party—which was commenced in the hour of political adversity, and continued when we emerged from the pressure of political thraldom; which was suggested by those whose patriotism supported our cause in the wosst of times, and whose wisdom adopted the best means of preserving an ascendancy which their perseverance had obtained—a usage, moreover, the practical effects of which have been to give efficacy to your exertions, to dispell and subdue discord, and to produce the best fruits attendant on a united exertion of your republican strength.

In making the designation of the counties from which the candidates for Senators at the ensuing election should be filled, it will be seen that every means has been resorted to for the purpose of obtaining the best information necessary to a decision on the conflicting claims of the three respectable Counties whose pretensions were submitted to us. That the most advisable course was adopted, to arrive at the unbisassed sentiment of the members of the District, and that the decision evinces a unamity affording at once the most satisfactory evidence of the justice and propriety of the selection ultimately made, as also the most flattering presage of the result of the contest, in which your duty and your country’s interest, will lead you to take active and zealous parts.

A particular discussion of the correctness of the decision thus made, is deemed at this moment as unnecessary as it would be unusual. Your representatives, will therefore, content themselves with assuring you, that in making that decision, a due regard has been had, and a full, and as they hope, impartial consideration given to the claims of the different Counties, as founded on their respective population their present and probably future representation in the different branches of our Legislature, and the effect which might be produced on the election generally.

That a designation thus made, will unite in its support, every sound man in the District, your representatives will not permit themselves to doubt. They are persuaded, that on ordinary occasions, the necessity of unanimity and vigor would be felt by their Republican brethren. But more especially at this time, when we are engaged in a just and indispensable war, in defence of rights which are inseparable from our freedom, with a cruel, oppressive and unrelenting foe, when instead of that harmony and zeal which ought to characterize a free people in a contest for their freedom, we are doomed to witness the humiliating and degrading fact; that even under the pressure of circumstances calculated to excite the livliest feelings, and rouse the strongest indignation of the American People, a desperate and aspiring opposition remain deaf to every sentiment of national honor and callous to every dictate of individual duty. When, instead of that unanimity which was so reasonably to have been expected, we find the torch of civil discord in full blaze in the east, and by its reflection discovering to our view, the malignant convulsions and paricidal efforts of a junto who have long been brooding over their Country’s prosperity and sighing for that state of national calamity, at which they now hypocritically affect to repine. When even in this State, which heretofore stood foremost in defence of our country’s rights, and was wont to claim the right of leading the nation’s van, opposition to government and covert aid to the enemy, have been reduced to system. When even here, our moral senses are assailed and annoyed by the heedless desperation of faction, and the public feeling disgusted by the brainsick ditties of a herd of “puny whipsters,” who while they think they “wear upon their baby brows the round and top of sovereignty” are most valiant in deriding every thing that is American. At such a time, when union and zeal are so pre-eminently necessary in our ranks, we cannot for a moment believe that any Republican will be found in the District, so lost to all sense of duty as to wish or attempt to destroy that unanimity, and throw the apple of discord in the Republican ranks.
