These widely-spreading trees are favourites with the black wasps, to which they attach their pensile nests. Externally the nests are like fancifully cut brown-paper sacks, or a series of such sacks arranged one above another, with frills and ornate cuttings, like the fancy paper grate-covers in English parlours in summer time. We avoided such trees religiously, and when there was no such terror as a big nest of wasps near, we could rest in comfort and examine the forest at leisure. We first saw besides countless grey columns, thousands of pendent slender threads and wavy lines, loops, festoons, clustered groups and broad breadths of grey mingled with more than studied disorder with darkest depths of green, lightened only by broad damp leaves reflecting stray glints of sunshine or sprays, and a magic dust of softened light perpetually shifting and playing, profound spaces of darkness relieved by a breadth of grey tree trunk, silvered rods of parasites, or fancy grey filigree of vine stems. As we surveyed the whole, the eye caught various crimson dots of phrynia berries, or red knots of amoma fruit, outer fringes of auburn leaves, a cap of a mushroom staring white out of a loose sheaf of delicate ferns, or snowy bits of hard fungi clinging like barnacles to a deeply-wrinkled log; the bright green of orchid leaves, the grey green face of a pendent leaf of an elephant-eared plant--films of moss, tumorous lumps on trees exuding tears of gum, which swarmed with ants, length after length of whiplike calamus--squirming and twisting lianes, and great serpent-like convolvuli, winding in and out by mazy galleries of dark shadows, and emerging triumphant far above to lean their weight on branches, running coils at one place, forming loops at another place, and then stretching loosely their interminable lengths out of sight.
