“Couldn’t he at least pay some attention to us?”

“It would perhaps be difficult to induce him to do so.”

Then turning to the attendant:

“Speak to him, Gaydon. Perhaps he will answer you.”

“Oh! he’ll answer me right enough, sir, never fear,” replied Gaydon.

He went up to the inventor and touching him on the shoulder, said gently: “Thomas Roch!”

The latter raised his head, and of the persons present he doubtless saw but his keeper, though Captain Spade had come up and all formed a circle about him.

“Thomas Roch,” continued Gaydon, speaking in English, “here are some visitors to see you. They are interested in your health—in your work.”

The last word alone seemed to rouse him from his indifference.

“My work?” he replied, also in English, which he spoke like a native.
