"A few occasionally, going to Touggourt, but seldom. They are formidable-looking fellows, in their indigo-coloured masks, which stain their skin blue, but they are tractable enough if one does not offend them."

There was only one room which could be made passably habitable for Saidee and Victoria, and they went into it, out of the hot sun, as soon as it could be prepared. The little luggage they had brought went with them, and the basket containing the two carrier pigeons. Saidee fed the birds, and scribbled a few words on a scrap of paper, to tell Sabine that they had arrived safely at Toudja. On second thoughts, she added a postscript, while Victoria unpacked what they needed for the night. "He chose the rendezvous," Saidee wrote. "I suppose I'm too superstitious, but I can't help wondering if his choice had anything to do with the ruined tower? Don't be anxious, though. You will probably receive another line to-morrow night, to say that we've reached the next stage, and all's well."

"I suppose you think I'm doing wrong to write to him?" she said to Victoria, as she took one of the pigeons out of its basket.

"No," the girl answered. "Why shouldn't you write to say you're safe? He's your friend, and you're going far away."

Saidee almost wished that Victoria had scolded her. Without speaking again, she began to fasten her letter under the bird's wing, but gave a little cry, for there was blood on her fingers. "Oh, he's hurt himself somehow!" she exclaimed. "He won't be able to fly, I'm afraid. What shall I do? I must send the other one. And yet—if I do, there'll be nothing for to-morrow."

"Won't you wait until after Mr. Caird has come, and you can tell about the little boy?" Victoria suggested.

"He mayn't arrive till very late, and—I promised Captain Sabine that he should hear to-night."

"But think how quickly a pigeon flies! Surely it can go in less than half the time we would take, riding up and down among the dunes."

"Oh, much less than half! Captain Sabine said that from the bordj of Toudja the pigeon would come to him in an hour and a half, or two at most."

"Then wait a little longer. Somehow I feel you'll be glad if you do."
