The ideas of a man on horseback are different to those which occur to
him when he is on foot. The difference is even more noticeable when he
is on the railway. The association of his thoughts, the character of
his reflections are all affected by the speed of the train. They "roll"
in his head, as he rolls in his car. And so it comes about that I am in
a particularly lively mood, desirous of observing, greedy of
instruction, and that at a speed of thirty-one miles an hour. That is
the rate at which we are to travel through Turkestan, and when we reach
the Celestial Empire we shall have to be content with eighteen.

That is what I have just ascertained by consulting my time-table, which
I bought at the station. It is accompanied by a long slip map, folded
and refolded on itself, which shows the whole length of the line
between the Caspian and the eastern coast of China. I study, then, my
Transasiatic, on leaving Uzun Ada, just as I studied my Transgeorgian
when I left Tiflis.

The gauge of the line is about sixty-three inches--as is usual on the
Russian lines, which are thus about four inches wider than those of
other European countries. It is said, with regard to this, that the
Germans have made a great number of axles of this length, in case they
have to invade Russia. I should like to think that the Russians have
taken the same precautions in the no less probable event of their
having to invade Germany.

On either side of the line are long sandhills, between which the train
runs out from Uzun Ada; when it reaches the arm of the sea which
separates Long Island from the continent, it crosses an embankment
about 1,200 yards long, edged with masses of rock to protect it against
