USUALLY we think of springtime as the song time of the year, but this does not apply to all singing creatures; there are some whose singing season is in the autumn. In this class are a few of our insect friends—the cicadas, grasshoppers, and crickets.

Strangely enough several of these autumn musicians are night singers. Though the grasshoppers and cicadas are day singers, the crickets hold the night world without much opposition, and of these perhaps the most wonderful musicians are the little green treecrickets.

These frail little pale-green creatures, belonging to the genus Ecanthus, do not follow the ways of the commoner field-crickets of the ground, but live in the trees. In appear

"THE DEVIL'S SLIDE" AND NONNEZOSHE They know that in early autumn a chorus of Roo-roo's" begins to come from the orchard, What kind of welcome would you expect if that it increases in volume, and by and by you should step up to the clerk's desk in a fades with the coming of the frost; and that first-class Eastern hotel, and register from is all. As in the case of the other crickets, Devil's Slide, Utah? Nevertheless, that is the only the ales sing. The two sexes are rather unlike, for, as shown in the two photographs on the preceding page, the female is more slender, with narrow wings, while the male has a wing spread (folded) that gives him a broad, flat back, tapering toward the head.

On the inner surface of each wing are two tiny instruments which might well be called a scraper and a rasp, and it is the subbing of the two that produces the vibrant, stridulous note that serves as a song. The wings are elevated almost to the perpendicular, and somewhat spread, as the strange note is rasped out on the air.

To the human ear it is melodious. It fills the August day and night with pulsating melody. To stand in the orchard on a still warm night of early autumn and hear hundreds of these voices in chorus is to hear one of Nature's strangest orchestras. Though all the singers or fiddlers do not strike the same note, varying by several tones, they fall roughly into tune and produce a pulsating, rhythmical sound that becomes tremendously strong in volume and power; the air fairly booms. While there is a steady undertone, resulting from the voices out of tune, the majority sing so correctly in time that the air throbs with a mighty, rhythmical, "Rooroo-roo!"
