is most abundant. The Cedar-bird eats cater- 

 pillars, spiders, and grasshoppers, but does most 

 marked good in destroying the elm leaf-beetle 

 that strips our village and city trees of leaves. 

 Mrs. Mary Treat writes of one town in which the 

 elms had been ruined for several years before the 

 Cedar-birds came, and which were afterward com- 

 paratively free from beetles. From one calcula- 

 tion, it is shown that 30 Cedar-birds would de- 

 stroy 9,000 worms during the month when the 

 cutworm caterpillar is' exposed. 



To prevent the Cedar-bird from eating culti- 

 vated fruit, and to attract it to secure its help in 

 destroying caterpillars, it would be well to plant

 such as blackberry, wild cherry, choke-cherry, 

 sour gum, flowering dogwood, rough-leaved dog- 

 wood, chokeberry, red cedar, Juneberry, hack- 

 berry, black haw, black elder, huckleberry, frost

 lows and the Shrikes. They are unique among 

 North American birds in having wax-like append- 

 ages on the tips of their wing-feathers (Fig. 72). 

 As we run over the groups of birds we have had, 

 we see how the Cedar-birds differ from them in 

 general characters. In the matter of coloration, 

 the earth, leaf, and stubble browns of the ground 

 birds are modified in them, for they approach
