"What have you colored your skins with?"

"We got some iodine from the doctor, sir, and mixed it with water till it was just thick enough to tinge our skin. It will wash pretty well off with plenty of scrubbing, but we mean to use walnut juice when we start; it lasts much longer, and is a better brown."

"I am not sure, boys, that you had not better leave your faces alone, they and your hands are so sunburnt that you would pass well enough, though you must dye your arms and legs. Fortunately, your hair is pretty dark, for you can't well carry dye. Think well over all these things, for your lives may depend on some trifle of this kind. I shall see you at mess."

So saying, Colonel Tritton walked on, leaving the boys to follow at their leisure. Just as they were about to turn off to make for the woods they saw a soldier coming along the road.

"That's Sam, if I am not mistaken, Peter, we will have some fun with him. We can trust him to say nothing in the regiment about meeting us like this."

The two boys accordingly sat down by a low wall by the roadside, and as Sam came up talked away to each other in Spanish. He passed without paying any attention to them. After he had gone a few yards, Tom said in a deep, loud voice, "Sambo." The black halted suddenly, and turned round. First he looked angrily at the boys, then he went to the side of the road and looked over the wall. Then with a very perplexed air he looked up and down the road.

"Who dat have impudence to call dis colored gentleman Sambo," he said to himself. "Some fellow did, dat for sartin, not dose little Spanish trash, dey not know Sam's name, some rascal in regiment; he's hid somewhere. I pound him to squash when I find him."

Muttering thus he turned to proceed on his way, but before he had gone twenty yards, he again heard a deep shout. "Here, you, Sambo."

The black jumped as if he was shot, "My golly," he exclaimed, and then walked back to the boys, who were talking together, shook his head and again looked over the wall. Then he stooped down to the boys, and shook his fist in their faces, "You little debils, you call Sambo, I pound you to squash." The boys both leapt to their feet with an air of intense surprise and alarm, and began to cry out in Spanish.

"No, can't be you," Sam said, "dis chile must be witched, no place for men to hide, sartin not dem boys. Stone wall can't call Sambo all by self, Sam's going out of mind. Oh! Lor, dis berry bad affair," and Sam sat down by the roadside with a face of such perfect bewilderment and dismay that the boys could stand it no longer, but went off together into a scream of laughter, which caused Sam to jump to his feet again. "What you larf for, what you larf for, you little rascals, you play trick, eh? you call Sambo, who taught you dat name?" and he seized the two boys and shook them furiously.
