The door is made in two parts, of the 

 dimensions shown, using the same kind of 

 material as was used for the siding of the 

 building. By nailing on the curved facial 

 boards to the ends and those on the sides, 

 together with the corner boards, a neat 

 looking building results. The boards fitted 

 at the top of the sides must be matched to 

 fit the projecting rafters. Care must be 

 taken to nail the corner boards as shown, 

 and in fitting the quarter-round molding, 

 nail it to only one of the boards. Then 

 when the ends and sides are taken down, 

 the molding will come with whichever 

 board it was nailed to. 



From the foregoing description, it will be 

 noted that the building can be taken down 

 very easily and in a comparatively short 

 time. If it is desired to do this, the thin 

 batten on the roof is first taken off and the 

 screws on one side of the cleats, joining the 

 rafters, taken out. the cleats remaining 

 fixed to the other rafter piece. Then 

 remove the cleats holding down the rafters 

 to the studs. The roof can now be lifted 

 off in two sections. Next remove two of 

 the screws in the angle-irons which hold 

 the ends and sides at the top. Only the 

 lag screws at the bottom now remain to be 

 taken out. A sloping runway is built at 

 the front, resting on several large stones. 



Marking an Automobile for 

 Positive Identification 



USUAL marks of identification on auto- 

 mobiles can be easily obliterated and a 

 popular make will be diflficult to claim. 

 Here is a method I have used for marking 

 tools, and it 

 can be a p - 

 plied in the 

 same way to 

 an automo- 

 bile so that 

 the car may 

 be identified 

 beyond ques- 

 tion. A small 

 piece of sheet 

 metal, preferably brass, is stamped with 

 the owner's name, or other inscription, 

 then rolled up closely and slipf)ed into a 

 hole drilled in the frame in some out-of-the- 

 way place. The hole is then plugged and 

 finished over so that it cannot be seen. 

 The owner can easily locate the place and 

 show conclusively that the car belongs to 

 him. — C. A. Johnson.

x\ New Combination Triangle for 

 Draftsmen's Use 



THE illustration shows a triangle com- 

 bining several unique features of 

 value to the draftsman. In mechanical 

 drawing two lines are generally laid out 

 first; namely, the vertical center line and 



A triangle with combinations that serve for 

 various tools other than the ordinary one 



the horizontal center line. If a line is 

 wanted parallel to A and 2 in. to the 

 right, the triangle is shifted along the 

 T-square to the f)osition as shown. By 

 running the pencil along the vertical edge of 

 the implement the desired result can be 

 obtained. If the line is wanted 2 in. to the 

 left, instead of to the right, it would simply 

 mean shifting, the triangle along the T- 

 square in the direction of the arrow C until 

 the 2-in. mark on the right horizontal scale 

 is flush with A, then by running the pencil 

 along the vertical edge of the implement the 

 line wanted can be drawn. The same 

 principle can be employed when measuring 

 below the horizontal center line B, using, of 

 course, the upper edge of the blade. 



An Emergency Clothes Hanger 

 Made from Roll of Paper 



WHEN traveling or visiting, one fre- 

 quently is so situated that a clothes 

 hanger is not available. A good substitute 

 may be made in a quick and simple way. 

 Roll up a newspaper loosely and tie it in the 

 middle with a piece of string, leaving a 

 loop by which to hang it. This may be 

 suspended from a gas bracket or from a 

 handy hook. — Jennie E. McCoy.
