The engine knew it, the whole machine repeated it, and sent vibrations through my body that were just like the movements of the waltz.

I was so much interested in this discovery that I forgot the problem of the Continuity of Time; and from that day to this, whenever I have heard that waltz,--one of the sweet Danube waltzes,--I have lived through that entire experience; the festive night, the misty morning, the abnormal consciousness of time, as if I had existed forever, without a break; the journey, the dim landscape, and the tune singing itself in my head.

Never can I hear that waltz without the accompaniment of engine wheels grinding rhythmically along speeding tracks.
I remained in Vitebsk about six months.

I do not believe I was ever homesick during all that time.

I was too happy to be homesick.
