 Whatever packing material is used, it 

 should come to the top of the container for 

 the kettle, and the box should lack about 

 4 in. of being full. A cushion or pad must 

 be provided to fit completely the space be- 



The cover with a deep rim and the con- 

 tainer for the cooking vessel within the box 



tween the top of the packing and the cover 

 of the box after the kettles are put in place. 

 This should be made of heavy goods, such 

 as denim and stuffed with cotton, crumpled 

 paper or excelsior. Hay may be used, but 

 it is somewhat odorous. 



The classes of food best adapted to the 

 cooker are cereals, soups, meats, vege- 

 tables, dried fruits, steamed breads and 

 puddings. When different foods are 

 cooked together in the fireless cooker they 

 must be such as to require the same 

 amount of cooking, since the cooker can- 

 not be opened to take the food out 

 without allowing a large amount of heat 

 to escape. It would not do to put foods 

 which need about IJ^ hours to cook in 

 a cooker with, say, a piece of meat that 

 requires several hours' cooking. 



A Driver for Holding a Screw While 

 Turning It 



TAKE a round piece of wood, some- 

 thing like a lead pencil, of the re- 

 quired length, run a fine 

 saw lengthwise through 

 the end of it; then take a 

 discarded clock spring, 

 cut two pieces of equal 

 lengths and insert them 

 in the saw with the 

 curves out. Wind it se- 

 curely, pinch the ends 

 together, insert them in 

 the slot of a screw and 

 you can hold it at any 

 angle. If a watch spring 

 is used and the ends 

 made keen enough the 

 device can be used to 

 drive very small screws. — E. L. Griffith.

Extension Holder for Hauling Long 

 Stock on Express Wagon 



THE holder is made of two bars, each 

 9 ft. long and % in. in diameter. 

 They are bent at right angles on one end 

 to make an upright 16 in. high. These 

 pieces are joined together with another 

 piece of the same stock welded in as at B. 

 The length of this piece will be regulated 

 by the width of the express wagon box on 

 the inside. 



The bars are held in place inside of the 

 wagon box with four pieces of metal 

 shaped as shown at C and made from 

 stock 1 in. wide and ]^l in. thick. These 

 are bolted to the upper surface of the 

 bottom of the wagon box.

Extension rods on a wagon box to hold the 

 pipe ends and keep them from lashing about 



The upper ends of these rods are thread- 

 ed for almost their entire length and 

 fitted loosely with two nuts. A crossbar, 

 D, made of stock 2 in. wide and % in. 

 thick is drilled to fit on the rod ends be- 

 tween the nuts, A. 



In hauling long rods, pipe or lumber the 

 holder is slipped in place in the clips, C, 

 and the material loaded on it. The cross- 

 bar, D, is then put on and the nuts ad- 

 justed to hold the load. This prevents 

 the long ends of the material extending 

 from the rear' of the box from lashing 

 about and makes it possible for the load 

 to be placed against the front end of the 

 wagon box, where it will not extend over 

 and strike the horse. This device is very 

 serviceable.- James E. Noble.
