A MISTAKE DISCOVERED.

JULIA Franklin was the only child of a man of large property, who, at the age of eighteen, left her independent mistress of an unincumbered income of seven hundred a year; she was a girl of a lively disposition, and humane, susceptible heart:

she resided in New-York with an uncle, who loved her too well, and had too high an opinion of her prudence, to scrutinize her actions so much as would have been necessary with many young ladies, who were not blest with her discretion: she was, at the time Montraville arrived at New-York, the life of society, and the universal toast.

Montraville was introduced to her by the following accident.

One night when he was upon guard, a dreadful fire broke out near Mr. Franklin's house, which, in a few hours, reduced that and several others to ashes; fortunately no lives were lost, and, by the assiduity of the soldiers, much valuable property was saved from the flames.

In the midst of the confusion an old gentleman came up to Montraville, and, putting a small box into his hands, cried--"Keep it, my good Sir, till I come to you again;" and then rushing again into the thickest of the croud, Montraville saw him no more.

He waited till the fire was quite extinguished and the mob dispersed;but in vain: the old gentleman did not appear to claim his property;and Montraville, fearing to make any enquiry, lest he should meet with impostors who might lay claim, without any legal right, to the box, carried it to his lodgings, and locked it up:

he naturally imagined, that the person who committed it to his care knew him, and would, in a day or two, reclaim it; but several weeks passed on, and no enquiry being made, he began to be uneasy, and resolved to examine the contents of the box, and if they were, as he supposed, valuable, to spare no pains to discover, and restore them to the owner. Upon opening it, he found it contained jewels to a large amount, about two hundred pounds in money, and a miniature picture set for a bracelet. On examining the picture, he thought he had somewhere seen features very like it, but could not recollect where. A few days after, being at a public assembly, he saw Miss Franklin, and the likeness was too evident to be mistaken:

he enquired among his brother officers if any of them knew her, and found one who was upon terms of intimacy in the family:

"then introduce me to her immediately," said he, "for I am certain Ican inform her of something which will give her peculiar pleasure."He was immediately introduced, found she was the owner of the jewels, and was invited to breakfast the next morning in order to their restoration.

This whole evening Montraville was honoured with Julia's hand;the lively sallies of her wit, the elegance of her manner, powerfully charmed him: he forgot Charlotte, and indulged himself in saying every thing that was polite and tender to Julia.

But on retiring, recollection returned. "What am I about?" said he:

"though I cannot marry Charlotte, I cannot be villain enough to forsake her, nor must I dare to trifle with the heart of Julia Franklin.
