When Mr. Grubb had been in the Chaco for seven years he went home to England for a vacation, the first vacation he had had. Other young men had come to help him, and the mission was so well established that it would not suffer in his absence.
Before he went away, he planned carefully for his return. He intended then to visit a distant tribe called the Toothli, to which Poit belonged, and he had already built a bullock road in that direction. He sent Poit to a distant settlement with seventeen head of cattle and other goods and told him that he was to settle down there and make friends with the people. He was not to sell the cattle to people who would use them for food, but only to those who would raise other cattle, because Mr. Grubb was very anxious for the natives to learn to care for stock.
Poit was to tell the Toothli that the missionaries would come and live with them if they would do certain things. They must give up making beer, and they must not hold feasts which lasted more than three days. They must work when they were called upon for the good of the whole settlement, and they must help to build the cart track and keep it clear. They must live at peace with their neighbors, and above all they must cease at once the killing of little children.
Poit had done so well, that this important work was entrusted to him and off he went with his cattle and his goods. He was very proud and at first he obeyed Mr. Grubb's directions. But alas, his pride in Mr. Grubb's confidence and his feeling of responsibility did not continue. He forgot what he had learned; he convinced himself that Mr. Grubb was gone for good; and he took possession of the property which Mr. Grubb had given him. He began to sell the cattle to people who used them for food, and he took the money for himself.
When Mr. Grubb came back, Poit was terrified. He had not believed Mr. Grubb's promise nor had he understood in the least how devoted Mr. Grubb was to his work. Now the money had to be paid over, and he had to give an account of the cattle, and he had spent a part of the money, and the cattle had been eaten. In order to cover his crime, he stole money from the missionaries. He was so clever that they did not at first suspect that he was the thief. But he could not bring the cattle back to life and soon he realized that discovery was at hand; Mr. Grubb would learn that he had not been faithful.
Mr. Grubb prepared at once to fulfil his promise to visit the Toothli people, and so little did he suspect Poit of wrong-doing that he made him the leader of the six Indians whom he took with him.
It was so hot that the party traveled by night to avoid the sun. They had a pretty comfortable track to walk on, but on both sides were thickets of trees and vines in which the twenty-four kinds of frogs croaked in twenty-four different notes, and everywhere were mosquitoes which flew out hungrily when they heard human beings approaching.
Suddenly Mr. Grubb looked round and saw that, of all his company, only Poit was in sight. He sent him back at once to find out why the others lingered. In a little while Poit reappeared and reported that one of the bearers had a thorn in his foot, and his companions were extracting it. They would all be along, he said, in a few minutes.
But the few minutes passed and the Indians did not come. Poit had wickedly told them that Mr. Grubb did not need them and that they might return toward the mission. He had dreamed that when his disobedience was found out, Mr. Grubb had killed him, and he had decided in terror that he must kill Mr. Grubb as soon as possible. He meant to go on for a few days until they had reached the Toothli country and then he would do the deed. He believed that the people of his tribe would help him to hide his crime.
Mr. Grubb noticed that Poit seemed downcast, but he did not dream what he had in his heart. The two went on alone, and still the other Indians did not overtake them. Poit suggested that perhaps they had gone home because they did not approve of the journey. Still Mr. Grubb did not suspect his evil intention, and they traveled on, arriving presently at the village which was Poit's home.
