The National Fast Day.

To-day is set apart by one of the president's proclamations as a day of national fasting and prayer. Viewed as a "war measure," in retaliation for a similar proceeding on the part of Jeff. Davis, it is one which we justify and indorse, and for the beneficial results of which let us feel as hopeful as we can. Of the expediency — even of the actual necessity, of occasional fast days in the "land of cotton," we have no doubt, and we are equally certain that a little spasmodic display of devotion up here in the north, will not prove damaging to our cause.

Let us in Illinois, among other objects of desire, to-day pray that the Washington tax commissioner may not take it into his head to require an internal revenue stamp to be affixed to the air we breathe or the water we drink; that Gen. Hascall, who rules the Hoosiers, may have no jurisdiction over citizens of the prairie state; that the rain on the Potomac may one day cease, and give "fighting Joe Hooker" an opportunity to show his metal; that Greeley's 900,000 men may enlist and stop the war within ninety days; that the comet may not retaliate on the president's bull; that greenbacks may cease to depreciate; that the Chicago Tribune may learn decency and honesty, and the telegraph try to tell the truth; that the plots of K. G. C.'s to abduct the president and create civil war in the north may be confounded; that the rebel army may one day find that last ditch, and Fremont be assigned to the command of our African recruits.

Let us also be thankful that we are permitted still to attend church on the Sabbath and to talk politics (under our breath) on week days; let us strive not to offend our military rulers by criticising their "war policies" or indulging any insinuations against the wisdom or the purity of that model assemblage of patriots, the late congress; let us congratulate ourselves that Chicago has not yet joined the southern confederacy, in spite of the copperhead triumph at her election, and above all that Washington is safe, and all quiet on the Potomac.

There are other subjects, of course, for prayer and thanksgiving, which will occur readily to every one; we have only indicated a few which were not specified in the proclamation, and which some might possible overlook in the exercises of the day.
