The letter referred to, (which was sent back from Ireland in consequence of some misdirection,) was full of kind feeling, and manifested on the part of the writers a firm and simple trust in the goodness of Providence. The post master sent word to the widows that this letter was in his possession, and accordingly was visited by the bereaved women, whose tears flowed fast as they gazed upon the record which recalled so vividly the kindnesses of their departed husbands. The little sum enclosed, as they stated, was the result of the united efforts of the two families, who cheerfully joined in this labor of love. How many a recollection of unmurmuring self-denial, with the hope that made it easy; how many a remembrance of bright anticipations of the happiness to be enjoyed, when the beloved one, for whose sake these efforts were made, should be received within their family circle; how many such things must have been brought to mind by the sight of the missive, so freighted with affection and memories of the past! The post master informed the widows that by returning the draft to the office from which it was purchased, they might obtain the money on it; but they replied that since it had once been dedicated to an object sacred both to the departed and their survivors, it must go back to Ireland, and fulfil its mission. So these poor stricken women, to whom ten pounds was a large sum, (even larger than when the letter was first sent,) and who much needed the comforts it would purchase, sent back the draft, and have since had the happiness of meeting their relative in America, and seeing the wishes of their husbands faithfully carried out. This is but one of many constantly recurring instances of generosity and devotion which come to the knowledge of post masters; and while we have put on record some of the blunders of an impulsive people, our sense of justice as well as inclination, has prompted us to make public the foregoing incidents, so forcibly illustrating the warm attachments that grace the IRISH HEART. * * * * * MY WIFE'S SISTER. The most ridiculous errors and omissions sometimes occur on the part of persons applying to post masters for missing letters. The following amusing correspondence will illustrate this phase of post-office experience:-- New York, 29th Jan. 1855. Post Master New York. Dear Sir, A week ago last Monday, I mailed two letters, both having enclosures, but of no intrinsic value, directed to my wife's sister in New Haven, Conn., neither of which have ever reached their destination. Very respectfully yours, W. B. H----. The above letter was forwarded to the post master of New Haven, after having been read by the New York post master. It was soon returned with the following pertinent inquiries:--
