I wish to make an explanation--that should perhaps be also an
apology--to the readers of the _Dial_.
To the magazine I make due acknowledgment for the permission to print

expanded since it appeared serially in the magazine. The temptation to
amplify my treatment of the theme was irresistible. If I have succeeded
in thus indulging myself without detriment to my story I shall be glad.
