"Calabar needs a brave heart and a strong body," said Mary. "I don't have much of a brave heart, but I often feel the need of it when I am sick and lonely." "Mary, you must go home to Scotland and rest," said Mammy Anderson, "then you will get well from the fever. You will never get well here." "That's true, Mammy," said Mary, "but you know that I cannot leave my field of work was until the Board of Missions says I may." "That's right, but you have a furlough coming. I do hope we hear from the Board soon." In June, 1879, the letter came. Mary read it gladly. It told her that she could come home for a year's vacation. It did not take Mary long to pack. She left for Scotland on the next steamer. There were tears in her eyes as she stood on the deck. There on the shore were her black friends waving good-by to their white ma. They were crying, too. "Come back again! Come back again! God bless you and keep you!" they said. Mary waved to them. "I will be back," she said. Mary loved Africa. She loved the people there, but she knew if she wanted to get well she would have to go home. Then, too, she was anxious to see her mother and sisters again. The ocean trip did Mary much good. The cool ocean breezes blew the fever away. It made her cheeks pink again. Every day she prayed for the people of Africa. She prayed that she might go back again. She prayed that more missionaries would be sent out to show these poor people the way to Heaven. How happy Mary's mother and two sisters were to have her with them again! And how happy Mary was to be with them! They could not hear enough about Calabar. It made Mary's mother very happy to know that her daughter had taught the black children the way to Heaven. She was glad to hear about the other missionary work which Mary had done. But other people, too, were anxious to hear about Calabar. So Mary had to speak at Wishart Church and other churches. Mary told about the heathen, the wicked things the heathen natives did to twins, the mean way they treated slaves, and the many other cruel, wicked things these people did. "There is only one thing that will change these people," said Mary. "There is only one thing that will turn these heathen from their sins. That is the Gospel of Jesus Christ, the good news about the Saviour. But who will tell these people about Jesus? We need many, many more missionaries. If you cannot go yourself, you can send gifts and offerings for this work. We need money so the missionaries can buy food and clothing. We need money so that they can build homes and churches and hospitals. Have pity on these poor people! Pity the poor little children! Help them now! Above all, pray for these people, and pray for your missionaries that God will bless their work with these lost souls."
