Next day (May 5th), at 10 o'clock, we left by the Baltimore and Ohio Railroad, sorry we had not more time to enjoy the hospitalities of our friends, and to see more of the interesting people and scenes with which we made such a short acquaintance; but, indeed, the number of attractions presented for the time that we had at our disposal was quite embarrassing enough, and whilst we were at Washington the party, broken up in detachments under the care of various friends, lost no time, but went to racecourses, galleries, and national institutions, crossed the Potomac to the heights of Arlington, and visited the cemeteries where tens of thousands of stone memorials, placed, as the dead men beneath them once stood, in orderly array, attest the severity of the tremendous conflict in which the first shots were fired, not very far from the spot, more than twenty years ago. It is said that there are about 15,000 bodies buried in one enclosure; even in death the white and the black are divided--the former are buried near Arlington House, the coloured men's remains lie half a mile or more away. Another cemetery, containing 5400 soldier's bodies, is near the Soldiers' Home. These and many other places were visited; but we must leave Washington at last, and were carried at express speed to the Shenandoah Junction. We are on our way to Harrisburg. Fortunately the day is bright and clear, and the sun not too warm, so that we can enjoy the charming scenery through which the railway passes, and we are interested in observing that the canal, in spite of the competition of the iron road, still keeps up navigation, and that strings of gaily-painted barges with the national flag are passing to and fro close at hand. The course of the Potomac, to which we now and then come near, is marked by the wooded heights which once formed the skirmish-ground of two great armies. It would not have been safe at one time for a man to have shown his head above the cutting of the canal, or to have ridden by the river-banks, for in all probability a Secesh bullet would have found him out or dismounted him, as there was fighting-ground all about; and the peaceful scene seemed strange to me when I contrasted it with the sight it presented as I saw it after the battle in which Senator Baker was killed and many Union men with him, and great gloom reigned at Washington--when General McClennan led all the troops that could be spared, who were pouring out in a long column on this road, and the country-side was alive with armed men in order to counteract the menaced invasion of Maryland. At the Shenandoah Junction, six miles west of Harper's Ferry, we halted for a while. It seemed to me as if it had not quite recovered from the ravages of war, and Harper's Ferry appeared as if the storm of battle that had passed over it--taken and retaken as it was so many times--had left an indelible mark of wreck and ruin about it. Nothing, however, can
