DEAR MORRITT,--Yours I have just received in mine office at the Register-House, which will excuse this queer sheet of paper. The publication of Rokeby was delayed till Monday, to give the London publishers a fair start. My copies, that is, my friends', were all to be got off about Friday or Saturday; but yours may have been a little later, as it was to be what they call a picked one. I will call at Ballantyne's as I return from this place, and close the letter with such news as I can get about it there. The book has gone off here very bobbishly, for the impression of 3000 and upwards is within two or three score of being exhausted, and the demand for these continuing faster than they can be boarded. I am heartily glad of this, for now I have nothing to fear but a bankruptcy in the Gazette of Parnassus; but the loss of five or six thousand pounds to my good friends and school-companions would have afflicted me very much. I wish we could whistle you here to-day. Ballantyne always gives a christening dinner, at which the Duke of Buccleuch, and a great many of my friends, are formally feasted. He has always the best singing that can be heard in Edinburgh, and we have usually a very pleasant party, at which your health as patron and proprietor of Rokeby will be faithfully and honorably remembered. Your horrid story reminds me of one in Galloway, where the perpetrator of a similar enormity on a poor idiot girl was discovered by means of the print of his foot which he left upon the clay floor of the cottage in the death struggle. It pleased Heaven (for nothing short of a miracle could have done it) to enlighten the understanding of an old ram-headed sheriff, who was usually nicknamed Leather-head. The steps which he took to discover the murderer were most sagacious. As the poor girl was pregnant (for it was not a case of violation), it was pretty clear that her paramour had done the deed, and equally so that he must be a native of the district. The sheriff caused the minister to advertise from the pulpit that the girl would be buried on a particular day, and that all persons in the neighborhood were invited to attend the funeral, to show their detestation of such an enormous crime, as well as to evince their own innocence. This was sure to bring the murderer to the funeral. When the people were assembled in the kirk, the doors were locked by the sheriff's order, and the shoes of all the men were examined; that of the murderer was detected by the measure of the foot, tread, etc., and a peculiarity in the mode in which the sole of one of them had been patched. The remainder of the curious chain of evidence upon which he was convicted will suit best with twilight, or a blinking candle, being too long for a letter. The fellow bore a most excellent character, and had committed this crime for no other reason that could be alleged, than that, having been led accidentally into an intrigue with this poor wretch, his pride
