Ah Important Article.To the exclusion of article of our owu we give the subjoined from the Louisville Union Press, and invite the reader’s attentionThe O. A. K.’s, or Sons of Liberty.—A foul brood which has been hatched in the ruins ot the nest of the “Golden Circle,” has recently appeared in raven plumage, chanting its music in notes born at Marathon and rejuvinated at Bunker Hill. This foul brood is the product of an adulterous union of Southern traitors and Northern and Western conspirators and is scattered mainly through Indiana, Ohio, Illinois, Missouri and Kentucky. We shall not pause to detail the machinery of this new treason. Its character has been fully developed in the newspapers ofMissouri and Indiana, and we shall confine what we have to say, to the developments in Kentucky. The whole affair has been vigilantly watched in this State, its leaders have been “spotted by the military authorities of Kentucky, and their doings and speech have been carefully bus banded for the day of reckoning. Some of the parties who have felt recently the grasp of the military hand, have been carefully watched in their incomings and outgoings, in their rising up and lying down, in their pantomime of treason that mutely sawed the air, fearful of peoplingthe atmosphere with the sounds of their wicked purposes, and in their cypher tablets that veiled the dark, horrible, mnrderous intents that never were surpassed in villainy outside of Pandemonium. In the most secret recesses of this treason, in its most uneasy, restless, haggard flitting from point to point, as well as in the occasional resting of its hellish pinions for a renewal of its mission of devastation and havoc, the unsleeping eye or loyalty has been keenly bent upon its every movement and every pause. At every gathering of these unclean beasts of rebeldom, no matter |how heavily shrowded were the pavilions of darkness in which they congregated, the undying vigilance of loyalty followed them with unswerving fidelity. If it were at all necessary we could easily tell this murderous crew where they met, who presided over their work ol villany, where they were; initiated into the horrible mysteries ot the third degree of the treasonable order, at what moment, in fact, they passed, by a horrid plunge, from the well secured privileges of citizenship, into fellowship with the busy devils who have vexed mankind from their first interview with the parents of mankind, down to the present moment. This is uot necessary now In its proper season this record will be given to the world.The people of Kentucky and all the loyal spirits of the land owe a profound debt of gratitude to the military authorities who have engineered the watching and blasting of this new phase of treason. They calmly and quietly watched this cradled iniquity until it grew to proportions that needed better binding material than swaddling clothes. Others were almost parajized by the rapid growth of this wickedness, and scarcely hoped for success in any movement against it. But Maj. Gen. Burdridge, Gen. Ewing and Col. Fairleigh felt the truth of the thought written on a window in Scotland more than a century since:“Tender handed stroke a nettle.And it stings you for your paim :Grasp ft like a man of mettle,And it soft as silk remains.''On Saturday, 30th of July, Geo. Burbridge and Col. Farleiuh were at Indianapolis, on a visit to Gov. Morton. It was will known that Judge Joshua Bullitt, who was elected to a Judgeship of the Court of Appeals by the Union voters of this judicial district, was the leader of the Kentucky branch of this treason. He has leen on the wing almost incessantly for months past among the traitors of Missouri, Illinois, Indiana and Ohio, and when not thus engaged, he was busy at home in seducing men from honor to ruin His various interviews of this kind are thor oughly known. We Bhall metely allude to one, where Judge Bullitt made a ten hours’ siege at one conspicuous Kentuckian, and he reported to his fellow conspirators his utter failure iu getting this man to swerve. We could detail matters of this kind that might cause Judge Bullitt almost to think that we were in the breast pocket of his coat, in all “the moon struck madness that spurred his evil spirit.On Saturday, 30tli July, Judge Bullitt reached Indianapolis in company with one of the busy conspirators from Missouri. The Judge hurried off from Indianapolis in order to have the checks cashed that were com cealed about his person, and to call hia fellow assassins together, to report progress. But, al,a8 for Judge Bullitt, he found“The best laid schemes o’ mice an’ ineii Gang aft a-gley;And lea’c us naught butignef and pain,For promisod joy.Before the Judge reached Louisville, the graBp of General Burbridge was upon him, and he was arrested as a traitor. The indignation of the deceived and outraged constituency who honored him with their confi dence, rages fiercely against Judge Bullitt’s treason. And many of the “sympathizers ” in our midst seem to be as indignant as the loyal men. In the course of the next few daysjafter the arrest of the Chief of the Ken lucky conspirators, various other members of S. L s were gathered. Among these is Wm. K. Thomas, Jailor of Jefferson county. Mr. Thomas was, at one time, one of the most zealous of the Union men of this city. He was very liberal, and thoroughly in earnest. In an evil hour for his peace, his honor and welfare, he forgot that the people of the United States had not confided to him the management of the war, and he under took to set up for himself. Very unfortunately for Mr. Thomas, the proof against him is such that, he could not look it in the face without a feeling of horror. We regret that he ever forgot his duty to the lawsAnother of the active engineers of this mischief is Dr. Kallus. Through the casualties of war and disease, this man reached the oominandership of the 15th Begiment of Kentucky Volunteers, a regiment that has earned its full meed of glory in many a well-contested field, and has nobly sustain ed Kentucky's proudest military claims. Dr. Kallus forgot the position assigned him, and so degraded himself, that Gen. Rosecrans dismissed him dishonorably front themilita ry service for disloyalty. From that field ofziue was engineered by this secret organization.We have much more to reveal respecting j the plans and designs of these men, but we I cannot spare the space to-day. We give i below a list of the arrests that have been I made. A great many of our readers will . remember that among these names are those of men who two weeks ago were in feverish anxiety during the impressment of horses, | because their loyalty was called in question. | They were utterly indignant that any one . could suspect the purity of their devotion to the United States. Some of them took numeraus witnesses before Col. Farleigh to j vouch for their loyalty, but alas! for the proof, Col. Fairleigh was in possession ot j tlie handwriting of some of these very cases, j which conclusively showed their activity in this organization. This should be a warn- ! ing to Union men not to be too supple in rushing forward to testify in matters of which they cannot positively be certain, where the military may be thwarted in their wholesome work. Those members of this order who were indignant at the idea of having their loyalty suspected, when the Government wanted the use of their horses, give a glowing illustration of Milton's thought:“That practiced falsehood under saintly show. Deep malice to conceal.The following are the names of some of those who have been arrested:•T. F. Bullitt, G. \V. G. Payne, Dr. U. F. Kalfus, W. T. Cassell, J. Colgan, W. K. Thomas, A. Harris, T.

ChambersFromjthe Washington Chronicle.The Postal LawOn looking over the act of Congress which was approved on the first inst., and now ac companied by the “notes” of the Postmaster General, we find several sections of very greatj importance to the pnblic generally. First we notice theLETTER-CARRIER SYSTEM.Letter-carriers will be appointed and their salaries fixed by the Postmaster General, as heretofore.Where letter-carriers are already appointed, their duty is to deliver all letters concerning which there is no positive direction to the contrary.It is the special duty of postmasters to provide that all letters are regularly, frequently and promptly delivered by the carriers, so that citizens may have no excuse for clinging to the old custom of calling at the post-office. The purpose ol the law, pro' viding for a free delivery of letters at. the houses of owners, is to promote the public convenience, and at the same time, reduce the labor in post offices Postmasters will especially discourage the use of private box es, and steadily aim at reducing them to the lowest number possible.In order to facilitate 'the carriers' work citizens must be induced to provide letterboxes at theit houses and places of bu9i-^ ness.Where carriers are not yet employed, postmasters should immediately recommend one or more for appointment—selecting only young, vigorous and reliable men. in whom the people may fully confideTo give this braach of the publio service the utmst efficiency, the Postmaster Gen eral has now established a letter carriers' desk in connection with the appointment division of his own department, and assigned thereto the experienced General St. John S. L Skinner, who will supervise the duties of the new desk in addition to those of the principal clerkshipof the appointment division.POSTAGE STAMPS AND STAMPED ENVELOPESThis section is specially designed to encourage partiis to purchase postage stamps and stamped envelopes as articles of trade, to be resold, and thus relieve postoffices of the labor connected with making sale9 in small quantities.Postmasters will accordingly sell postage stamps in quantities not less than $100 in value, and stamped envelopes in packages containing notices than five hundred envelopes at a discount of five per cent, from the bace value of stamps and from the current prices of envelopes, including the stamps.In order to obtain credit lor the discount thus allowed, a voucher must be procured in each case, signed by the purchaser and postmasters, showing the original value of the stamps and envelopes of each denomination, the amount deducted, and the actual amount paid tor them.CORRESPONDENCE WITH FOREIGN COUNTRIESSec 8. Establishes uniformed rates oi United States postage, without regard to distance, upon ail letters, Ac., addressed to for eign countries with which postal treaties or arrangements have not bee i concluded. Heretofore the United States postage on letters addressed to such countries baa varied in amount, according to distance ; ten cents, the single rate, having been changed for distances not exceeding 2,500 miles, and twenty cents the single rate for any distance over 2,000 miles; but in future the United States postage is to be levied and collected at the office of mailing or delivery at unifarm, rates, as follows :Ten cents per single rate of half ounce on letters.Two cents each on newspapers ; and the established domestic rates on pamphlets, periodicals, and other kinds of printed matter.These rates do not, of course, apply to the correspondence exchanged with foreign countries under existing international postage ar rangementeCavalry horses command one hundred and sixty dollars each in Vermont. There arc no belter beasts under the saddle than the choice Messenger, Black Hawk and Morgan horses of that State, ot which the two latter belong to one family. Horses are worth their full value over the whole'country now, Rnd farmers can do no wiser thing than buy up all the breeding mares which may corne within their reach, and so be pre-
