"We are only a mile from the Box Tunnel."
"Do you always laugh a mile from the Box Tunnel?" said the lady.
"Invariably."
"What for?"
"Why, hem! it is a gentleman's joke."
Captain Dolignan then recounted to Miss Haythorn the following:
"A lady and her husband sat together going through the Box Tunnel; there was one gentleman opposite; it was pitch-dark. After the tunnel the lady said, 'George, how absurd of you to salute me going through the tunnel!' 'I did no such thing.' 'You didn't?' 'No; why?' 'Because somehow I thought you did!'"
Here Captain Dolignan laughed and endeavoured to lead his companion to laugh, but it was not to be done. The train entered the tunnel.
Miss Haythorn. Ah!
Dolignan. What is the matter?
