It was a relief to be out in the fields again after the foul odors of the night, and the travelers were off before dawn. The country looked more familiar to Mackay this morning, for they passed through wheat and barley fields. It seemed so strange to wander over a man's farm by a footpath, but it was a Chinese custom to which he soon became accustomed.
The sun was blazing hot, and it was a great relief when they entered the cool shade of a forest. It was a delightful place and George Mackay reveled in its beauty. Ever since he had been able to run about his own home farm in Ontario his eyes had always been wide open to observe anything new. He had studied as much out of doors, all his life, as he had done in college, and now he found this forest a perfect library of new Things. Nearly every tree and flower was strange to his Canadian eyes. Here and there, in sheltered valleys, grew the tree-fern, the most beautiful object in the forest, towering away up sometimes to a height of sixty feet, and spreading its stately fronds out to a width of fifteen feet. There was a lovely big plant with purple stem and purple leaves, and when Dr. Dickson told him it was the castor-oil plant, he smiled at the remembrance of the trials that plant had caused him in younger days. One elegant tree, straight as a pine, rose fifty feet in height, with leaves away up at the top only.
This was the betel-nut tree.
"The nuts of that tree," said Mr. Ritchie, standing and pointing away up to where the sunlight filtered through the far-off leaves, "are the chewing tobacco of Formosa and all the islands about here. The Chinese do not chew it, but the Malayans do. You will meet some of these natives soon."
On every side grew the rattan, half tree, half vine. It started off as a tree and grew straight up often to twenty feet in height, and then spread itself out over the tops of other trees and plants in vine-like fashion; some of its branches measured almost five hundred feet in length.
The travelers paused to admire one high in the branches of the trees.
"Many a Chinaman loses his head hunting that plant," remarked Mr. Ritchie. "These islanders export a great deal of rattan, and the head-hunters up there in the mountains watch for the Chinese when they are working in the forest."
Mackay listened eagerly to his friends' tales of the head-hunting savages, living in the mountains. They were always on the lookout for the farmers near their forest lairs. They watched for any unwary man who went too near the woods, pounced upon him, and went off in triumph with his head in a bag.
The young traveler's eyes brightened, "I'll visit them some day!" he cried, looking off toward the mountainside. Mr. Ritchie glanced quickly at the flashing eyes and the quick, alert figure of the young man as he strode along, and some hint came to him of the dauntless young heart which beat beneath that coat of Canadian gray.
Two days more over hill and dale, through rice and tea and tobacco-fields, and then, in the middle of a hot afternoon, Mr. Ritchie began to shiver and shake as though half frozen. Dr. Dickson understood, and at the next stopping-place he ordered a sedan-chair and four coolies to carry it. It was the old dreaded disease that hangs like a black cloud over lovely Formosa, the malarial fever. Mr. Ritchie had been a missionary only four years in the island, but already the scourge had come upon him, and his system was weakened. For, once seized by malaria in Formosa, one seldom makes his escape. They put the sick man into the chair, now in a raging fever, and he was carried by the four coolies.
