And what is this? A yellow-jacket has found an ambrosial attraction here upon the bramble leaf. Meanwhile a great black and white paper-hornet has seen his opportunity, and is soon slyly approaching behind the sipper. That he has designs on that jacket and its contents is apparent. In a moment the onslaught is consummated, and in the struggle which ensues the black assailant relieves his victim-of his watch presumably, for he has captured the entire garment, which he soon rifles and discards with some show of satisfaction.
And so my carnival proceeds. So it began with the dawn; so it will continue till dusk; and through the night, with new revels, for aught I know, and will be prolonged for days or weeks.

Reflective reader, how often, as you have strolled through some nook in the suburban wood, have you paused in philosophic mood at the motley relics of good cheer which sophisticated the retreat, so pathetically eloquent of pristine joys to which you had been a stranger? Here in my present picnic is the suggestive parallel, for even though no such actual episodes as those I have described had been witnessed by me, an examination of the premises beneath my bramble were a sufficient commentary. These were the unimpeachable witnesses of the pleasures which I have pictured. Dismembered butterfly wings strewed the grassy jungle, among which were a fair sprinkling from that black and white halo already noted. Occasional dead wasps and detached members of wasp and hornet anatomy were frequent, while the blue glitter of the bodies of flies lit up a shadowy recess here and there, showing that Musca had not always so correctly gauged his comparative wing resources as my observation had indicated.
It was interesting to discover, too, down deep among the herbage, another suggestive fact in the presence of a shrewd spider that showed a keen eye to the main chance, and had spread his gossamer catch-all beneath the bramble. It was all grist into his mill, and no doubt his charnel-house at the base of his silken tunnel could have borne eloquent testimony alike to his wise sagacity and his epicurean luxury.
I have pictured my picnic, and the question naturally arises, what was it all about-what the occasion for this celebration? There was certainly no distinct visible cause for the social gathering upon this particular bramble-bush. There were a number of other bramble-bushes in the near neighborhood which, it would seem, should possess equal attractions, but which were ignored. In what respect did the one selected differ from the others?
This bramble had become the scene of my carnival simply because it chanced to be directly beneath an overhanging branch of pine some twenty feet above. Here dwelt mine host who had issued the invitations and spread the feast, the limb for about a foot space being surrounded by a colony of aphides, or plant-lice, from whose distilling pipes the rain of sweet honey-dew had fallen ceaselessly upon the leaves below. The flies, butterflies, and ants had been attracted, as always, by its sweets; the preoccupied convivial flies, in turn, were a tempting bait for the wasps and hornets, and my dragon-fly and mock bumblebee found a similar attraction in the neighborhood.
An examination of the trunk of the pine showed the inevitable double procession of ants, both up and down the tree, with the habitual interchange of comment; and could we but have obtained a closer glimpse of the pine branch above, we might certainly have observed the queer spectacle of the small army of ants interspersed everywhere among the swarm of aphides. Not in antagonism; indeed, quite the reverse; herders, in truth, jealously guarding their feeding flock, creeping among them with careful tread, caressing them with their antennæ while they sipped at the honeyed pipes everywhere upraised in most expressive and harmonious welcome.
This intimate and friendly association of the ants and aphides has been the subject of much interesting scientific investigation and surprising discovery. Huber and Lubbock have given to the world many startling facts, the significance of which may be gathered from the one statement that certain species of ants carry their devotion so far as literally to cultivate the aphides, carrying them bodily into their tunnels, where they are placed in underground pens, reared and fed and utilized in a manner which might well serve as a pattern for the modern dairy farm. Indeed, after all that we have already seen upon a single bramble-bush, would it be taking too much license with fact to add one more pictorial chronicle-an exhilarated and promiscuous group of butterflies, ants, hornets, wasps, and flies uniting in "a health to the jolly aphis"?
