Maples and occasionally elms suffer severely at times from the attacks of this scale insect. A few full grown individuals are represented in the accompanying figure. The insect may be recog- nized by its brownish scale at one end of a large white cottony mass. In bad attacks, the insects may form festoons along the under side of the smaller limbs. Remedies. Like the elm bark louse this species obtains its food by suction from the underlying tissues and therefore can not be poisoned. The cottony mass covering the body of the female protects her from contact insecticides, conse- quently little can be done till the unprotected young appear in July, when spraying with kero- sene emulsion or whale oil soap solution will be found most effective. VALUE OF OUR NATIVE BIRDS The valuable services rendered by our native birds should be more generally recognized. It is a matter of record that after the introduction of the English sparrow, most of our native birds were driven from the cities and that the tus- sock moth caterpillars, previously hardly noticed as pests, became destructive. It is very true that prior to the intro- duction of the English sparrow, a measuring worm had been a pest in various cities, but this is an additional proof of the effect birds may have upon insect life. In the same way there are a number of birds known to prey on the tent caterpillars and were these friends of man accorded the protection and encouragement they deserve, instead of being hunted and driven away, it is very probable that the ravages of these pests would be much less severe than at present. Robins, orioles, chipping sparrows, cat birds, cuckoos, the red eyed, white eyed and warbling vireos, cedar birds and nuthatches have been observed feeding on forest tent caterpillars by Miss Soule. " The nuthatches would stand by a patch of larvae lying close
