"Let's see that," said Knowlton, dropping on one knee. "Looks pretty sore. Yes, it's more than sore; it's infected. How'd you get it, anyway?" No answer. Knowlton probed his face keenly. Rand straightened out his legs, wriggled his toes, and scowled. "Queer!" muttered the lieutenant, rising. "He looks as if he actually didn't know how he got that wound. You'd think he'd remember that much, anyhow. I sure am afraid his head is all scrambled up." He went to the canoe, returned with his meager medical kit, and knelt again. "Now listen here, Rand. I don't know how well you understand me, but I'm taking the chance. This foot has to be opened up and cleaned out. Otherwise you're going to have serious trouble with it. I'm going to hurt you. If you raise a row you'll get an anæsthetic--a swift punch under the ear. Better sit still and make no fuss." With which he went to work. He did a thorough job, and there was no doubt that it hurt. But Rand gave no trouble, nor even a sign of pain--except that he dug his fingers into the dirt. "Good boy!" the amateur surgeon approved, when he finished. "You're a Spartan--if you happen to remember what that is. Now we'll move on. But before we go, wash your face good and hard. Get that tribe paint off. These Indians with us don't like it. You're no Indian, anyhow; you're white, like us. Savvy? White man. Wash off paint!" He rolled up his kit and returned to the canoe. The Mayorunas, men and women, were entering their own craft. Rand sat motionless a moment, McKay and the Brazilians watching him keenly. Slowly then he got up of his own accord, limped to the water's edge, and began to scrub his face. When he desisted the marks still showed, for the red dye clung stubbornly to his skin; but they were fainter than before. The other men eyed him thoughtfully, none speaking. He settled himself in his former place, curled up, and began to doze. "A queer fish!" Pedro said, softly. "Is he crazy or not?" "Hanged if I know," replied McKay. "He's no maniac, anyhow. I'd give real money to know just what his mental condition is. But we can forget him for a while. I'm going to let you fellows sleep by turns now. I had some sleep last night; you've had none at all. Merry, your eyes need rest. You curl up in the bow and snooze one hour. Then another man, and so on. And how about letting Tucu lead the parade again?" "Excellent, Capitao! I was thinking of that." Lourenço talked to Tucu, who swung out into the current. The boat of the white men followed, then the others. At a steady cruising speed the brigade surged on downstream. Knowlton's allotted hour passed. Pedro took his place and was instantly asleep. In turn he was aroused, and Lourenço laid down his paddle. But just then Tucu's canoe slowed and floated in to the left bank.
