steam-launch rammed the paint off her dahabiyeh, and a young man flung
himself over the rail and ran toward her, her annoyance passed, and with
a sigh she sank into his outstretched, eager arms.

Half an hour later Ainsley laughed proudly and happily.

"Well!" he exclaimed, "you can never say I kept _you_ waiting. I didn't
lose much time, did I? Ten minutes after I got your C.Q.D. signal I was
going down the Boston Post Road at seventy miles an hour."

"My what?" said the girl.

"The sign!" explained Ainsley. "The sign you were to send me to tell
me"--he bent over her hands and added gently--"that you cared for me."

"Oh, I remember," laughed Polly Kirkland. "I was to send you a sign,
wasn't I? You were to 'read it in your heart,'" she quoted.

"And I did," returned Ainsley complacently. "There were several false
alarms, and I'd almost lost hope, but when the messengers came I knew
them."

With puzzled eyes the girl frowned and raised her head.

"Messengers?" she repeated. "I sent no message. Of course," she went on,
"when I said you would 'read it in your heart' I meant that if you
_really_ loved me you would not wait for a sign, but you would just
_come_!" She sighed proudly and contentedly. "And you came. You
understood that, didn't you?" she asked anxiously.
