And what we see is only, we feel, a stray sample of what there is to be seen. What may there not be in those forest depths which we dare not enter for fear of losing our way! What other towering forest monarchs might we not come across if we plunged into the forest! What other exquisite flowers, what insects, what birds, what animals! What wealth of insect life may there not be at the tops of the trees where the fierce sunshine hidden from us by their leaves is drawing out their flowers! What may there not be going on in the ground beneath us! We know, that in these forests, perhaps near enough to see us, though their forms are hidden by their likeness to their leafy surroundings and the dappled sunlight, are animals as various as elephants, tigers, leopards, foxes, squirrels, and bats; birds as various as hawks, parrots, and finches; and insects from butterflies, bees, and wasps to crickets, beetles, and ants. The forest, we know, in addition to all the wealth of tree and plant life, is teeming with animal and insect life, though of this we are able to see very little, so carefully do animals conceal themselves. In the night they emerge, and in the morning and evening there is a deafening din of insect life. But at noonday there is a soft and solemn hush, and we are tense with curiosity to know all that is going on in those mysterious forest depths and up among the tree-tops, so close but so impossible of access. The great forest is the very epitome of life. Concentrated here in small compass is every form and variety of living thing, from lowliest plant to forest monarch, from simplest animalcule to elephant, monkey, and man. There is life and abundant life all about us. But it is not the noisy, clamorous, obtrusive life of the city. It is a still, intense life, full of untold possibilities for good or harm. And herein lies its mystery: we see much, but we feel that there is infinitely more behind. Of this life of the forest in all its richness, intensity, and variety we shall come to know more as we ascend the Teesta Valley till it reaches the snows, and tropical plant and animal life changes first to temperate and then to arctic forms. But first we must note some beauties of the valley itself. * * * The valley of the great Teesta River, the valleys of its tributaries, the gorges through which the main river and its tributaries rush, the cascades pouring in succession down the mountain-sides, the sequestered glens and dells--all these have beauties which the terrific rain and the mists in which they are usually enveloped do not hide but augment.
