During part of our journey, we skirted round steep mountain barriers, which, at times, towered above us with their impenetrable masses of fir-trees, at others, being thickly sprinkled with snow and tipped with hoar-frost, shone resplendent in the sunlight, as if silver dust had been shaken all over them, while here and there peeped out the snow-capped towers of some old castle or baronial hall. I do not pretend that these hills would have looked anything wonderful, had they not been covered with snow, and had not the pellicles of ice, formed on the fir trees by a thick fog the night before, first run into tears, and then been frozen hard, covering the trees with brilliants which sparkled in the sun. These decorations, indeed, gave them an air of fairyland. On arriving at Darmstadt I took leave of Sherwell and my fellow-travellers, who were going on to Hamburg, and took the train to Mayence. It was very late when I got there, and I stayed the night at the Railway Hotel; for, having a sick officer's pass, I could break my journey where I pleased, which was a great convenience, besides being a cheap mode of travelling. I had practically nothing to pay; my sufficient warrant was the pass, stamped with the royal seal, which I exhibited to inquiring officials. Mayence is not interesting. I went on next morning as early as I could, had to wait at Coblentz and Bonn to allow some special military trains to pass, and did not get into Cologne till the afternoon. The Rhine scenery, which one gets at times from the train, is very fine; but somehow this was the grand disappointment of my journey. It did not come up to my expectations; and I felt far more delight on viewing the unrivalled beauties of our own Killarney, and of the river Blackwater. But I had not yet gone up the Rhine in a steamboat, which is quite another expedition than the one I was taking just then. From Cologne, which I explored in a few hours, I travelled by Aix la Chapelle to Liège. At the Hôtel de l'Europe my quarters seemed comfortable; but I had no longer a free billet, and might consider myself to be now in the enemy's country. It was the 16th, and I went off to call on my friend Vercourt, with whom I spent the forenoon. Then by Ostend, London, and Holyhead, I prosecuted my journey, and arrived in Dublin on the morning of the 19th, and at home at Scarteen on the 22nd. My furlough was made out for a month: but eight days after my arrival, a telegram came from Dr. Pratt, saying:-- "I return to-morrow; go to Versailles as soon as possible, find out Ambulance, and join it".
