Edith Nesbit,
The Railway Children
(1905)
“ Bobbie and Phyllis and Peter counted them as they passed. The foremost ones hesitated a moment at the foot of the ladder, then their eyes caught the gleam of scattered whiteness along the line and they turned towards the tunnel, and, by ones and twos and threes and sixes and sevens, disappeared in the dark mouth of it. The last one, in a red jersey, seemed to be extinguished by the darkness like a candle that is blown out. "They don't know what they're in for," said the foreman; "it isn't so easy running in the dark. The tunnel takes two or three turns." ”
