A Set of initials the above will afford-- R-Ove through them in order, they form a droll word. I L-eave you to solve it--’t will cure a disease; De-Velop the riddle--’t will set you at ease. D-Espair not, but hope; ’t is easily guessed: L-Ike etching on copper in gay colors dressed, E-Tch it down on your hearts, and there let it rest. _Elizabeth Town, N. J., April 9, 1842._ DEAR SIR: Though perhaps not so young as the generality of your admiring readers, I am confident that there can be none who are more delighted than myself with your works, and particularly your Museum, which is now being published. Of course, I was the more pleased when I noticed the addition of a “puzzle column,” of which I am decidedly fond. I have solved with correctness all the puzzles that have appeared in your Museum, with the exception of Puzzle No. 5 in the April number, which so far passes my comprehension, that, after repeated endeavors after its solution, I have flattered myself that it is a hoax; but if it is not, I must confess it is the hardest puzzle I have seen for some time. Are not the following correct answers to the April puzzles?--No. 1, “Mother.” No. 2, “Charles Dickens.” No. 3, “Boston and Worcester Railroad.” No. 4, “Prince de Joinville;” and Master Bare-Head’s, “Massachusetts.” I forward you an original puzzle, for which I do not profess any very extraordinary difficulty. I am a name of 23 letters. My 5th, 21st, 7th, 10th, 22d, is a Russian noble. My 17th, 18th, 20th, 20th, 12th, 2d, is a valuable metal. My 1st, 10th, 15th, 16th, is a legal writing. My 4th, 14th, 13th, 17th, 12th, is a pleasant amusement. My 11th, 3d, 8th, is seen whenever it is not invisible. My 2d, 12th, 21st, 4th, 12th, 2d, is what if all men were, the world would be happier. My 19th, 12th, 7th, 7th, 23d, 9th, 19th, 6th, 9th, 12th, 6th, 19th, is the title of a justly celebrated periodical. My 22d, 3d, 9th, 9th, 14th, 6th, is a street where my whole is found. If you think the above worthy a place, you can publish it. You may hear from me again soon. My sheet is full, so I have but to subscribe myself, Very respectfully, W. F. W. _Saturday, April 8, 1842._ DEAR SIR: I have taken the liberty to send you this puzzle, which I suppose almost any of your readers can unravel. I am a name of 13 letters.
