same shape, and made of galvanized iron. The upper division 

 (18 inches long, 10 inches wide, and 4 inches deep) is used to melt the 

 food, the lower is heated by fuel, and serves to keep the upper part 

 warm ; there is also a round pan with a long handle which is placed 

 between the upper and lower receptacle over the fuel when the 

 apparatus is closed, and a tin ladle. Any ironmonger can easily make 

 one of these apparatuses from the illustrations. 



Figure 3 shows clearly how the food is to be poured on 

 when the warming apparatus is used. The pan, held in the left 

 hand, contains the food taken from the upper iron receptacle, and 

 serves at the same time to catch the fat that drips from the branches. 



FIG. 2. HEATING APPARATUS (OPEN). 



If the food is poured on by two people, the upper receptacle can be 

 used instead of the pan. One person holds the receptacle with both 

 hands, while the other ladles out the mixture with the spoon and 

 pours it on. 



As the solid substances sink to the bottom of the boiling fat, the 

 mixture should be frequently stirred.

 kind of feeding-place. 



For this reason, and because the birds are plainly visible, the 

 " food- tree " affords a very interesting opportunity for observing them
