him. Picked him up and set him down again; eh?"
"Sure. One hand!" boasted the giant. "Eradicate him not be heavy. More as a sack of flour now."
"No, poor Eradicate is getting pretty old and thin," commented Tom. "He can't move very quickly. But you should have let him come, Koku. It makes him feel badly when he thinks he can't be of service to me any more."
"Man say he in hurry." The giant spoke softly, as though he felt the gentle rebuke Tom administered. "Koku run quick tell you—bang on door."
"Yes, you banged all right, Koku. Well, it can't be helped, I reckon. Where is this strange man? Who is he? Did you ever see him before?"
"Me no can tell. Master. Not sure. But him now be at the outer gate. Eradicate watch."
"All right. I'll go and see who it is. I don't want any strangers poking around here, especially with the plans of my new gyroscope lying in plain view."
Before he left the laboratory Tom swept into a desk drawer the mass of papers and blue prints, and locked the receptacle.
"No use taking any chances," he remarked.
