WOLF, GOAT, AND CABBAGES.--First he takes over the goat; he then returns and takes the wolf; he leaves the wolf on the other side, and brings back the goat; he now takes over the cabbages, and comes back once more to fetch the goat. Thus the wolf will never be left with the goat, nor the goat with the cabbages.

THE DOUBLE HANDCUFFS.--This is the way to do it. C must gather up into a loop the string which binds his hands, pass it under the string fastened round either of B's wrists, and slip it over B's hands. This done, both will be set free. To replace the strings, reverse the process.
$Wood Carving.$--The best kinds of wood include white holly, walnut and sycamore, and pieces of empty cigar boxes, often Spanish cedar, are not to be despised. A pocket-knife, some bradawls, a few files, flat, round and triangular, a fine saw and some coarse sandpaper complete the tools needed for most of the work.
Draw very carefully upon paper the design with which you wish to ornament some article you may have made with wood. When you have at last drawn the design quite accurately there are many ways in which you may transfer the drawing to the wood. It may be pasted upon the wood so that paper and wood will be cut away together in those parts that are to fall below the general surface of the wood and at the end the paper that remains may be washed away. Another way is to cut out the design with scissors, lay it upon the wood and go carefully round the edges with a lead pencil; or you may without cutting it out place it upon the wood and prick through the design or at any rate the principal points with a pin. If you were to scribble with crayon, coloured chalk or pencil upon the back of the paper and were then to lay the paper upon the wood and go over the design with a hard point, using some pressure, the design would be transferred to the wood, or still another way would be to use carbon paper (see Chap. XXIV.) between the paper and the wood instead of scribbling upon the back of the paper.
However, we will suppose the design in some way or another has been placed in pencil upon the wood. Now with regard to every part in which the intention is to take out the wood completely from front to back bore a hole. Then take your fret-cutter's saw or dentist's saw and unfastening one end put this end through the hole and fasten it again. Saw perpendicularly.
