Major McDuff mustered us in. He did it after this fashion: First he walked out into the yard of the War Department, where the company stood at 'parade rest,' or the nearest militia approach thereto, waiting to be absorbed. Then he had us marched across the yard and halted; then up it; then down it; then back to the first position; then forward in a line a few paces; then, by the right flank, into the back yard, where he left, us, at a 'rest,' for two hours and fifty-three minutes, while he retired into the War Department building, probably to ascertain if the thing was regular. Then, at the fifty-fourth minute, or thereabout, after the second hour, he caused us to be marched into our original position. After gazing at us uneasily for a few minutes, he proceeded to inspect our arms with the utmost care: the importance of which manoeuvre will more fully appear from the fact that they intended to take us, and did take many of us, _sans_ lock, stock, or barrel. Then he told us that we were--called into the--service--of the--United States--for--three months--to serve in the District--not to go beyond the District--under any circumstances. Then he called the roll, so accurately (never having seen it before) that nearly all of us recognized our names, and in hardly more than two and three quarters the time it would have taken the orderly sergeant to do it. Then we were told to hold up our right hands, and a stout party, well known to all early volunteers, stepped forward from wherever he had been before, and, introducing himself by exclaiming, in solemn and cavernous tones, 'THE FOLLOWING IS THE OATH!' swore us in. Then, after another short adjournment of half an hour, we were marched to our barracks. That was a queer organization, the 1st D.C. Vols., composed as it was of a cloud of independent companies--thirty-five, or thereabout, in all, I think--all made up of men from everywhere, largely in the tadpole stage of Unionism, and all sworn in for service in the District, not to go beyond the District. Early in May they were organized into eight battalions of four or five companies each, commanded by lieutenant-colonels, majors, or the senior captains. Nearly every company occupied its own separate 'armory' or barracks, and all the officers and men lived at home when not actually on guard or other duty!
