But Mackay was all for pushing forward, and Captain Bax was no less eager. So they spent a night in the forest and the next day marched on up another and higher range. As they journeyed, the travelers could not but burst into exclamations of delight at the loveliness about them. Behind those great trees and in those tangles of vines might lurk the head-hunters, but for all that the beauty of the place made them forget the dangers. The great banyan trees whose branches came down and took root in the earth, making a wonderful round leafy tent, grew on every side. Camphor trees towered far above them and then spread out great branches sixty or seventy feet from the ground. Then there was the rattan creeping out over the tops of the other trees and making a thick canopy through which the hot tropical sun-rays could not penetrate. And the flowers! Sometimes Mackay and Bax would stand amazed at their beauty. They came one afternoon to an open glade in the cool green dimness of the forest. On all sides the stately tree-ferns rose up thirty or forty feet above them, and underneath grew a tangle of lovely green undergrowth. And upon this green carpet it seemed to their dazzled eyes that thousands of butterflies of the loveliest form and color had just alighted. And not only butterflies, but birds and huge insects and all sorts of winged creatures, pink and gold and green and scarlet and blue, and all variegated hues. But the lovely things sat motionless, sending out such a delightful perfume that there could be no doubt that they were flowers,--the wonderful orchids of Formosa! Mackay was a keen scientist, always highly interested in botany, and he was charmed with this sight. There were many such in the forest, and often he would stop spellbound before a blaze of flowers hanging from tree or vine or shrub. Then he would look up at the tangled growths of the bamboo, the palm, and the elegant tree-fern, standing there all silent and beautiful, and he would be struck by the harmony between God's work and Word. "I can't keep from studying the flora of Formosa," he said to Captain Bax. "What missionary would not be a better man, the bearer of a richer gospel, what convert would not be a more enduring Christian from becoming acquainted with such wonderful works of the Creator?" At last they stood on the summit of the second range and saw before them still more mountains, clothed from summit to base with trees. They were now right in savage territory and their guide clambered out upon a spur of rock and announced that there was a party of head-hunters in the valley below. He gave a long halloo. From away down in the valley came an answering call, ringing through the forest. Then far down through the thicket Mackay's sharp eyes descried the party coming up to meet them. Just then their own guide gave the signal to move on, and the missionary and Captain Bax walked down the hill--the first white men who had ever come out to meet those savages.
