no flange, and it can be stiffened by nailing 3x2- 

 inch wood round it (on the inside). If the lower pan 

 has been fitted with iron bars crossed over the top, there 

 is no need to stiffen the bottom of the upper tray. 



When in use, the top pan is placed on the bottom pan, 

 and this is supported on two of the heaters described in 

 (a) above. For better and more even heat, a piece of 

 sheet iron should be placed between the heater and the 

 bottom of the lower pan. If it is to be used as a water 

 heater it must be made water tight and should be made 

 of galvanized material. It should also be fitted with two 

 steam escape pipes 2 inches in diameter by 1 foot long 

 to take the excess steam away from the drying meal. 

 When used as a water heater, the bottom bath should 

 not be filled more than half full, and care should he taken 

 to see that it does not boil dry. 



If the lower pan is to be used as an air heater, it is best 

 to make it of black iron. In this case, care must be taken 

 to avoid overheating the drying meal. 



In any case, galvanized iron is the best material for 

 the upper pan, although this is not essential. 



(e) Grinder. (Figure 18) 



A good grinder can be made from a stout barrel with 

 both ends intact. Take a piece of sound, square lumber, 

 about 3x3 inches, and around the center of each 

 end of the barrel cut a hole to fit this bar tightly. Pass 

 the bar of 3 x 3 inches through both holes so that it sticks 

 out about 15 inches at each end. A couple of stout nails 

 driven into the bar of wood will hold the barrel in this 

 position. 



About 6 inches clear of the barrel at each end, round 

 the 3 x 3-inch bar for a distance of about 3 inches. 



Next cut a hole about 6x6 inches in the middle of the 

 side of the barrel. This is for putting things into and 

 taking them out of the barrel. It must be fitted with a 

 snug cover that will not fall off or out. 



Take reasonably heavy pieces of lumber and make a 

 frame similar to the one shown in Figure 18. Let the 

 rounded part of the bar through the barrel turn in a 

 notch cut in the lumber as shown in the Figure. Nail a 

 strip of leather^ metal or lumber over the top of the notch
