Before us the banks of the roaring river were lined with lush vegetation; great trees raised their leafy branches far above the waters; the brilliant, scarlet sward was lapped by the little wavelets and everywhere bloomed gorgeous flowers and shrubs of many hues and shapes. Here was a vegetation such as I had never seen before upon the surface of Barsoom. Here were forms similar to those with which I was familiar and others totally unknown to me, yet all were lovely, though some were bizarre. Emerging, as we had, from the dark and gloomy bowels of the earth, the scene before us presented a view of wondrous beauty, and, while doubtless enhanced by contrast, it was nevertheless such an aspect as is seldom given to the eyes of a Barsoomian of today to view. To me it seemed a little garden spot upon a dying world preserved from an ancient era when Barsoom was young and meteorological conditions were such as to favor the growth of vegetation that has long since become extinct over practically the entire area of the planet. In this deep valley, surrounded by lofty cliffs, the atmosphere doubtless was considerably denser than upon the surface of the planet above. The sun's rays were reflected by the lofty escarpment, which must also hold the heat during the colder periods of night, and, in addition to this, there was ample water for irrigation which nature might easily have achieved through percolation of the waters of the river through and beneath the top soil of the valley. For several minutes Nur An and I stood spellbound by the bewitching view, and then, espying luscious fruit hanging in great clusters from some of the trees, and bushes loaded with berries, we subordinated the esthetic to the corporeal and set forth to supplement our meal of raw fish with the exquisite offerings which hung so temptingly before us. As we started to move through the vegetation we became aware of thin threads of a gossamer-like substance festooned from tree to tree and bush to bush. So fine as to be almost invisible, yet they were so strong as to impede our progress. It was surprisingly difficult to break them, and when there were a dozen or more at a time barring our way, we found it necessary to use our daggers to cut a way through them. We had taken only a few steps into the deeper vegetation, cutting our way through the gossamer strands, when we were confronted by a new and surprising obstacle to our advance--a large, venomous-looking spider that scurried toward us in an inverted position, clinging with a dozen legs to one of the gossamer strands, which served both as its support and its pathway, and if its appearance was any index to its venomousness it must, indeed, have been a deadly insect.
