MY DEAR SIR,--I am greatly obliged to you for your kind note and inclosure of to-day. I had never seen the Sanatorium pamphlet, and have been greatly pleased with it. The reasons for such an Institution, and the advantages likely to result from it, could not have been more forcibly or eloquently put. I have read it twice with extreme satisfaction. You have given me hardly less pleasure by sending me the Instructions of the Children's Employment Commission, which seem to me to have been devised in a most worthy spirit, and to comprehend every point on which humanity and forethought could have desired to lay stress. The little book reaches me very opportunely; for Lord Ashley sent me his speech on moving the Commission only the day before yesterday; and I could not forbear, in writing to him in acknowledgment of its receipt, cursing the present system and its fatal effects in keeping down thousands upon thousands of God's images, with all my heart and soul. It must be a great comfort and happiness to you to be instrumental in bringing about so much good. I am proud to be remembered by one who is pursuing such ends, and heartily hope that we shall know each other better.--My dear Sir, faithfully yours, CHARLES DICKENS. Dr SOUTHWOOD SMITH. Another characteristic and genial letter, dated half a-year later, appears to refer to some proposed expedition, in the course of which Dickens was to see on the spot some place where children were at work in a coal-mine:-- DEVONSHIRE TERRACE, _Wednesday, June the Second, 1841_. MY DEAR DR SMITH,--I find it can't be done. The artists, engravers, printers, and every one engaged have so depended on my promises, and so fashioned their engagements by them, that I cannot with any regard to their comfort or convenience leave town before the nineteenth. At any other time I would have gone with you to John-o'-Groat's for such a purpose; and I don't thank you the less heartily for not being able to go now. If you should see one place which you would like me to behold of all others, and should find that I could get easy access to it, tell me when you come back, and I'll see it on my way to Scotland, please God. I will send your papers home by hand tomorrow.--In haste, believe me with true regards, faithfully yours, CHARLES DICKENS. Dr SOUTHWOOD SMITH. The following year, Dickens, being about to proceed to Cornwall, wrote to my grandfather asking his advice as follows:-- DEVONSHIRE TERRACE, _Saturday, October Twenty-second, 1842_. MY DEAR SIR,--I have an expedition afoot in which I think you can assist me.
