As we lay at the side of this flue, we soon discovered that butterflies were hovering about us; no, not hovering, but flying swiftly up between the rocks from somewhere down the flue. I could scarcely believe my eyes. What could any living thing be doing here?—and of all things, butterflies? This was three or four thousand feet above the last vestige of vegetation, a mere point of volcanic rock (the jagged edge-piece of an old crater) wrapped in eternal ice and snow, with sulphurous gases pouring over it, and across it blowing a wind that would freeze as soon as the sun was out of the sky.
But here were real butterflies. I caught two or three of them and found them to be vanessas (Vanessa californica), a close relative of our mourning-cloak butterfly. They were all of one species, apparently, but what were they doing here?
Scrambling to the top of the piece of rock behind which I had been resting, I saw that the peak was alive with butterflies, and that they were flying—over my head, out down over the crater, and out of sight behind the peak, whence they reappeared, whirling up the flue past me on the wings of the draft that pulled hard through it, to sail down over the crater again, and again to be caught by the draft and pulled up the flue, to their evident delight, up and out over the peak, where they could again take wings, as boys take their sleds, and so down again for the fierce upward draft that bore them whirling over Mount Hood’s pointed peak.
Here they were, thousands of feet above the snow-line, where there was no sign of vegetation, where the heavy vapors made the air to smell, where the very next day a wild snowstorm wrapped its frozen folds about the peak—here they were, butterflies, playing, a host of them, like so many schoolboys on the first coasting snow!
CHAPTER III
A CHAPTER OF THINGS TO SEE THIS SUMMER
I
The dawn, the breaking dawn! I know nothing lovelier, nothing fresher, nothing newer, purer, sweeter than a summer dawn. I am just back from one—from the woods and cornfields wet with dew, the meadows and streams white with mist, and all the world of paths and fences running off into luring spaces of wavering, lifting, beckoning horizons where shrouded forms were moving and hidden voices calling. By noontime the buzz-saw of the cicada will be ripping the dried old stick of this August day into splinters and sawdust. No one could imagine that this midsummer noon at 90° in the shade could have had so Maylike a beginning.
