On reaching his horse, M'Arthur unloosed him, sprung on his back, and quick as thought, lifted the lady behind him; and having secured her to himself, by passing a silk neck-cloth around both, continued his flight--at first cautiously, till he cleared the loose stones and brushwood with which the place was encumbered; and then at full speed for the distance of eight or ten miles, when, being aware of his near approach to Kingston, and, consequently, to a situation of comparative safety, he reined in the exhausted animal; and it was now that an extraordinary denouement connected with the fate and fortunes of the fugitives took place. It was now, and not till now--for circumstances had hitherto permitted no conversation between them--that M'Arthur learned who the lady was whom he had so gallantly rescued from the brutality of the rebel negroes. Having checked the speed of his horse, M'Arthur turned round to his fair companion, and said, "May I now ask, madam, to whom I have had the honour of doing this little piece of service to-night?" "Don't you know me, Mr M'Arthur?" was the reply, in a soft and gentle tone, not unmingled with surprise that, as the speaker had recognised her deliverer, she had not been recognised by him. "No, indeed, madam," said M'Arthur, turning again round, but now with a look of intense curiosity; for, although his answer had been in the negative, the tones of the voice were familiar to him.

The exclamation of surprise and delight--for this feeling was also strongly expressed in it--which we have just recorded, Mr M'Arthur followed up, by inquiring how she had come into the dreadful situation in which he had found her. This Miss M'Donald briefly explained, by stating that a party of insurgent negroes had attacked her father's premises, burned his mills to the ground, plundered his house, and, on their retreat, had carried her along with them. Much more than this passed between the lovers, thus strangely brought together; but we do not think it necessary to record it; and, therefore, not to interrupt the progress of our story, we proceed to land them safely at Mr M'Donald's residence, a short distance from Kingston, where Mr M'Arthur left his fair charge, and proceeded himself to the town just named--Mr M'Donald being there at the moment, on some matters connected with the insurrection. On his finding the latter--
