Eradicate held the envelope carefully upside down, and read—or rather pretended to read—the name and address. Eradicate knew well enough where Mary lived, for this was not the first time he had gone there with messages from his young master.

"Massa Tom shore am a fine writer," mused the negro, as he slowly turned the envelope around. "I cain't read nobody's writin' but hisen, nohow."

Had Eradicate been strictly honest with himself, he would have confessed that he could not read any writing, or printing either. His education had been very limited, but one could show him, say, a printed sign and tell him it read "Danger" or "Five miles to Branchville," or anything like that, and the next time he saw it, Eradicate would know what that sign said. He seemed to fix a picture of it in his mind, though the letters and figures by themselves meant nothing to him. So when Tom told him the envelope contained the name and address of Miss Nestor, Eradicate needed nothing more.

He rummaged about in some odds and ends in the corner of the laboratory, and brought out a strong, wooden box, which had a cover that screwed down.

"Dat'll be de ticket!" Eradicate exclaimed. "De mahogany present will jest fit." Eradicate took some excelsior to pad the box, and then, dropping inside it the gift, already wrapped in tissue paper, he proceeded to screw on the cover.

There was something printed in red letters on the outside box, but Eradicate could not read, so it did not trouble him.

"Dat Miss Nestor shore will laik her present," he murmured. "An' I'll be mighty keerful ob it' laik Massa Tom tole me. He wouldn't trust dat big lummox Koku wif anyt'ing laik dis."

Screwing on the cover, and putting a piece of wrapping paper outside the rough, wooden box, with the letter in his hand, Eradicate, full of his own importance, set off for Miss Nestor's house. Tom had not returned from the telephone, over which he was talking to Mr. Titus.

The message was an important one. The contractor said he had received word from his brother in Peru that his presence was urgently needed there.

"Could you arrange to get off sooner than we planned, Tom?" asked Mr. Titus. "I am afraid something has happened down there. Have you sent the first shipment of explosive?"
