Of the “Penny Dreadfuls,” and of “blood and nastiness,” so called, we had never before heard, but we did not think it remarkable that a man so gifted as our correspondent should earn forty-five shillings a week by writing for the cheaper periodicals. It did not, however, appear to us probable that any one so remunerated would be willing to leave that engagement for another which should give him only thirty shillings. When he spoke of the “filth of his present position,” our heart began to bleed for him. We know what it is so well, and can fathom so accurately the degradation of the educated man who, having been ambitious in the career of literature, falls into that slough of despond by which the profession of literature is almost surrounded. There we were with him, as brothers together. When we came to Mr. Grimes and the Spotted Dog, in Liquorpond Street, we thought that we had better refrain from answering the letter,--by which decision on our part he would not, according to his own statement, be much disappointed. Mr. Julius Mackenzie! Perhaps at this very time rich uncles and aunts were buttoning up their pockets against the sinner because of his devotion to the Spotted Dog. There are well-to-do people among the Mackenzies. It might be the case that that heterodox want of comprehension in regard to The Trinity was the cause of it: but we have observed that in most families, grievous as are doubts upon such sacred subjects, they are not held to be cause of hostility so invincible as is a thorough-going devotion to a Spotted Dog. If the Spotted Dog had brought about these troubles, any interposition from ourselves would be useless. For twenty-four hours we had given up all idea of answering the letter; but it then occurred to us that men who have become disreputable as drunkards do not put forth their own abominations when making appeals for aid. If this man were really given to drink he would hardly have told us of his association with the public-house. Probably he was much at the Spotted Dog, and hated himself for being there. The more we thought of it the more we fancied that the gist of his letter might be true. It seemed that the man had desired to tell the truth as he himself believed it.
