THE BOY ENGINEERS: WHAT THEY DID, AND HOW THEY DID IT, is an illustrated book published by Messrs. G. P. Putnam's Sons. It seems to have been written for readers living in England, but young amateur machinists anywhere would find it an entertaining book. It gives good practical hints about the management of tools, and explains how to turn and carve in wood and metal, how to make a clock, an organ, a small house, and how to set up a steam-engine. The type is large, and the style easy and pleasant. THE RIDDLE-BOX. VERY EASY SQUARE-WORD. 1. A pointed implement of brass or wood. 2. Wrath. 3. Not old. A.W., AND F.E.D. DECAPITATIONS. 1.
