Mackay had just recovered from one of those violent attacks of malaria from which he suffered so often now, and he was still looking pale and weak. So Sun-a, a bright young student-lad, came to the study door with the suggestion, "Let us take Lu-a for Kai Bok-su to ride."

There was a laugh from the other students and an indulgent smile from Kai Bok-su himself. Lu-a was a small, rather stubborn-looking donkey with meek eyes and a little rat tail. He was a present to the missionary from the English commissioner of customs at Tamsui, when that gentleman was leaving the island. Donkeys were commonly used on the mainland of China, and though an animal was scarcely ever ridden in Formosa, horses being almost unknown, the commissioner did not see why his Canadian friend, who was an introducer of so many new things, should not introduce donkey-riding. So he sent him Lu-a as a farewell present and leaving this token of his good-will departed for home.

Up to this time Lu-a had served only as a pet and a joke among the students, and high times they had with him in the grassy field behind the missionary's house when lessons were over. In great glee they brought him round to the door now, "all saddled and bridled" and ready for the trip. The missionary mounted, and Lu-a trotted meekly along the road that wound down the bluff toward Kelung. The students followed in high spirits. The sight of their teacher astride the donkey was such a novel one to them, and Lu-a was such a joke at any time, that they were filled with merriment. All went well until they left the road and turned into a path that led across the buffalo common. At the end of it they came to a ravine about fifteen feet deep. Over this stretched a plank bridge not more than three feet wide. Here Lu-a came to a sudden stop. He had no mind to risk his small but precious body on that shaky structure. His rider bade him "go on," but the command only made Lu-a put back his ears, plant his fore feet well forward and stand stock still. In fact he looked much more settled and immovable than the bridge over which he was being urged. The students gathered round him and petted and coaxed. They called him "Good Lu-a" and "Honorable Lu-a" and every other flattering title calculated to move his donkeyship, but Lu-a flattened his ears back so he could not hear and would not move. So Mackay dismounted and tried the plan of pulling him forward by the bridle while some of the boys pushed him from behind. Lu-a resented this treatment, especially that from the rear, and up went his heels, scattering students in every direction; and to discomfit the enemy in front he opened his mouth and gave forth such loud resonant brays that the ravine fairly rang with his music.

A balking donkey is rather amusing to boys of any country, but to these Formosan lads who had had no experience with one the sound of Lu-a's harsh voice and the sight of his flying heels brought convulsions of merriment. "He's pounding rice! He's pounding rice!" shouted the wag of the party, and his companions flung themselves upon the grass and rolled about laughing themselves sick.

With his followers rendered helpless and his steed continuing stubborn, Mackay saw the struggle was useless. He could not compete alone with Lu-a's firmness, so he gave orders that the obstinate little obstructer of their journey be trotted back to his pasture.

"And to think that any one of us might have carried the little rascal over!" he cried as he watched the donkey meekly depart. His students looked at the little beast with something like respect. Lu-a had beaten the dauntless Kai Bok-su who had never before been beaten by anything. He was indeed a marvelous donkey!

So the journey to the Kap-tsu-lan plain was made on foot. It was a very wearisome one and often dangerous. The mountain paths were steep and difficult and the travelers knew that often the head-hunters lurked near. But the way was wonderfully beautiful nevertheless. Standing on a mountain height one morning and looking away down over wooded hills and valleys and the lake-like terraces of the rice-fields, Mackay repeated to his students a line of the old hymn:

Every prospect pleases and only man is vile.

Around them the stately tree-fern lifted its lovely fronds and the orchids dotted the green earth like a flock of gorgeous butterflies just settled. Tropical birds of brilliant plumage flashed among the trees. Beside them a great tree raised itself, fairly covered with morning-glories, and over at their right a mountainside gleamed like snow in the sunlight, clothed from top to bottom with white lilies.

But the way had its dangers as well as its beauties. They were passing the mouth of a ravine when they were stopped by yells and screams of terror coming from farther up the mountainside. In a few minutes a Chinaman darted out of the woods toward them. His face was distorted with terror and he could scarcely get breath to tell his horrible story. He and his four companions had been chipping the camphor trees up in the woods; suddenly the armed savages had leaped out upon them and he alone of the five had escaped.
