Dora noticed that the tall man occasionally glanced towards the door, and presently began to beckon to somebody who was presumably standing in the doorway. After a time the person beckoned to entered the post-office, and, as he did so, Miss Cook, who was sitting next to Dora, gave vent to a little gasp.

"What's the matter, dear?" inquired Dora.

"That--that's--Mr Somers!" exclaimed Miss Cook.

"And who is the other?" asked Dora, who was not greatly impressed by Mr Somers's appearance.

"That must be his friend, Mr Mortimer."

Quite unconscious of the fact that their identity was no secret in the post-office, the Long 'Un and Koko proceeded to compile telegrams.

"What a lot of forms Mr Mortimer is tearing up!" whispered Dora to her friend.

"Evidently sending a telegram to a girl," replied Miss Cook, who was still looking agitated, and whose thoughts were naturally trending in a sentimental direction.

Dora smiled. The sight of Koko standing on tip-toe, and craning his head over the Long 'Un's arm, was certainly smile-inspiring. So Dora smiled.

Presently Mortimer withdrew his head and shoulders from the compartment, and turned towards the counter. It should be added that the various communications suggested by Koko had all been condemned as worthless by the Long 'Un, who, with some pains, had finally evolved the following bald and uninspiring message: "Annie arrives nine to-night. Please meet. Jim."
