Writtca for Tai Courier. Washington. D. C, Marcli 12, 1880. General Logan fairly frightened the Demócrata out of tbeir wits on the Fitz John Porter ca9e by liis admirable speech, and when at its close the Ilepublican cauous decided that it was best to keep up the dif cus3ion as long as the Democrats desired, the zealous Confederates began to look about for some uieans of retreat. Finally they have found temporary comfort in postponingtho bilí fur a time. The Demócrata of the House are no more fortúnate. Some inconsiderate member called up the bill to prohibit political assessmcnts, and assailed the Republioan party. The retort has been seriously datnaging to the Democratie charaoter. The basty Demoorats wish thcy hadn't. The object of tli ís bill is to disfrancbise a large nuinber of soldiers who draw pensions, and in other ways to reduce the Ilepublican vote. It has no honest purpose, and it is belieyed that on the final vote several Democrats will voto against it. And still tbe Democratie majority do not go on with the business of the session. It would seem to reasonable men that after their repeated failures to mako political capital by their course, they would learn something, and get tbrough with the session as soon as possible. Waiting for Ilepublican blunders, thoy experience only disappointment, and have too much time to conimit blunders themselves. It is now said that some of tho leaders, notwithstanding the late decisión of the Supreme Court confirming the Constitutionality of the non laws, and the duty ot (Jongress to control Federal elections, threaten to withhold appropriations for the enforcement of these laws. This will be the biggest blunder yet, and will commit the Democratie party to dislnyalty and lawlessness beyond dispute. The report copine from General Grant that he will be in New Orleans about the lóth, gives rise to the supposition that he is coming into the political field to take observations, and if the prospect is not then sufficiently encouraging, he will withdraw. In despair at the way in which Tilden is carrying on his canvass for the Presidency, seyeral other Democratie candidatos are using all Mirts of means to lead liim off. Among other expedienta they are trotting out a largo nutnber of dark horses. This will not scare Mr. Tilden, who is an oíd campaigner and knows how to go fur anything he wants.
