---Lewis Carroll
Through the Looking-Glass,
near the beginning of Chapter 3.

From the illustrated version
[The Complete Illustrated Lewis Carroll,
Wordsworth Editions, 1991,
with an Introduction by A. Woollcott, illustrations by J. Tenniel]
the guard looks like a train conductor, but
was probably called a guard in the Victorian period. The guard is
moving between the compartments on an outside rail, and so is actually
shutting the window, and moving on to the
next compartment. I think Alice is sharing her compartment
with a Goat and a Beetle, or a gentleman dressed in white paper.
