Banding a Tree Trunk to Catch 

 and Destroy Moths 



WHEN the codling moth larva has 

 done its best to destroy the ap- 

 pearance of the ripest and rosiest fruits 

 it can find, it seeks a place to spin a 

 cocoon, and for this purpose it generally 

 crawls up or down a tree trunk. Hence 

 the usual method 

 of trapping the 

 moth is to wrap 

 a band of burlap 

 around the tree 

 trunk. An im- 

 provement on this 

 method, devised 

 by E. H. Sigler, 

 of the United 

 States Bureau 

 of Entomology, 

 employs a wire 

 screen over the 

 burlap band to 

 form a trap into which the larva enters 

 and spins its cocoon, but from which 

 it cannot escape as a moth. 



To make the trap, strips of burlap 

 six inches wide are folded into three 

 thicknesses. The loose bark from the 

 lower branches and trunk of the tree is 

 removed. A strip of this burlap is folded 

 once around the trunk and held in place 

 by large tacks, driven in such a way that 

 the edge projects about one-fourth of 

 an inch beyond the burlap. Black- 

 painted wire screening with twelve 

 meshes to the inch is then cut into strips 

 six inches wide, and the edge of each 

 strip is folded twice, allowing one-fourth 

 of an inch to each fold. 



The strip of screening should be long 

 enough to allow for an overlap of three 

 to four inches when placed around the 

 tree over the burlap. It is tacked to the 

 tree so that both the upper and lower 

 edges fit snugly against the bark. The 

 projecting tacks used to fasten the burlap 

 prevent the wire from pressing against 

 the cloth. To make sure that no moths 

 can escape through the openings along 

 the edges of the trap or along the flap, 

 a thin coating of pitch tar may be 

 used. 



The traps may be placed on the tree 

 during the winter or in the spring, not 

 later than one month after the petals have 

 dropped. 



Cleaning the Gilded Portion on 

 Picture Frames 



GILT picture frames and chandeliers 

 will, in the course of time, get dirty 

 and turn black. Procure a box of wall 

 paper cleaner and rub some of it over the 

 gilt frame or chandelier. This removes 

 the grease and dirt. Next boil some onions 

 in water so as to get a strong solution. 

 Dip a soft cloth in it and wipe over the 

 frame, polishing with a dry cloth. 



Cooling Camp Food by the Evapora- 

 tion Method 



/VWAY from an ice supply it is often 

 l\ difficult to keep the food in good con- 

 dition when no spring is near. However, 

 a very efficient refrigerator that will go a 

 long way in keeping the camp food fresh 

 can be made from a small wood box 

 mounted on stilts as shown in the illustra- 

 tion. Shelves and a door are put in to 

 hold the various dishes. 



The whole is then covered with flannel 

 which reaches down into the water below.

Wood box cloth covered and mounted on 

 stilts in a brook to keep food by evaporation 



The evaporation from the cloth will cool 

 the contents of the box in a very efficient 

 manner. Such a device also keeps the 

 food away from the crawling things that 

 infect the woods. — Thos. W. Benson.
