To Prevent a T-Square from Slip- 

 ping on a Drawing Board 



TO KEEP a T-square from slipping 

 on a sloping board, especially 

 where the angle is 45 deg. or more, place 



The rubber bands on the blade of the 

 square keeps it from slipping on the board 



two ordinary rubber bands on the blade, 

 one near the head and the other at the 

 end. These bands will also keep the 

 blade up from the drawing surface and 

 well away from the freshly drawn ink 

 lines. — ^Joseph Briscoe, Jr. 



A Home-Made Fireless Cooker 

 for the Camp 



ON a camping trip, any suggestion 

 which will tend to reduce the labor 

 of cooking meals is generally welcome. 

 One of the easiest ways to cook meals in a 

 satisfactory and thorough manner is with 

 a fireless cooker. It is a simple matter 

 to make such an article, the only mate- 

 rials necessary being a barrel, a tin pail 

 with cover holding about 8 quarts, 

 some strips of asbestos paper, plenty of 

 old newspapers, a few pieces of cloth, 

 and some flour to make a paste similar to 

 that used by paper-hangers. If the news- 

 papers are lacking one can use hay or 

 pine needles. 



After collecting the necessary materials 

 start the construction of the cooker by 

 sawing the barrel in half. Cover the bot- 

 tom with a 2-in. thickness of newspapers 

 and lay a few sheets of asbestos paper on 

 top. Then place the pail, after wrapping 

 with several thicknesses of asbestos 

 paper, in the center of the barrel. Pack 

 newspapers all around the pail, pressing 

 them down as tight as possible. It is 

 advantageous to pour a little paste in 

 with the newspapers from time to time 

 in order to make a compact mass. When 

 the packing reaches the level of the top 

 of the pail, pour plenty of paste over the 

 papers and let the whole harden. 



For a cover to the cooker, make a bag 

 which will fit inside the barrel and which 

 will completely cover the pail. Fill the 

 bag with newspapers, making a compact 

 pad of at least a 3-in. thickness. This 

 pad can be nailed to the head end of the 

 barrel. 



After the paste has dried completely, 

 remove the pail from the packing, taking 

 care that the sheets of asbestos remain to 

 form the lining for the mold in which the 

 pail is set. 



To use the outfit, start the food, which 

 is to be cooked, boiling over the fire in 

 the cooker pail. When it is boiling w^ell, 

 put it into the mold of the cooker and 

 place the padded cover over the pail. 

 A large stone will keep the cover pressed 

 firmly down onto the pail so that no heat 

 will escape. Let the meal cook all night 

 or all day, having no fear that the con- 

 tents will be cooked too much. The most 

 delicious boiled dinners, cereals, etc., can 

 be cooked in this manner with the ex- 

 penditure of little time and energy, so 

 that one may enjoy the camping trip 

 to the utmost. 



Portable Stove for Campers and 

 Automobilists 



A SIMPLE portable stove can be 

 easily made out of an oil-stove 

 top and four iron rods. The rods should 

 be sharpened at one end, so that they 

 may be easily driven into the ground 

 when they are to be used. The other 



The top of an oil stove with four rods for 

 legs makes a convenient stove for campers 



ends are bent into a loop surrounding 

 the metal of the stove-top and support- 

 ing it when the stove is in use. All that is 

 necessary in packing the stove is to fold 

 the rods in. The stove then becomes 

 a flat piece taking up very little room.
