"Not a bit," King answered. "It's a trick of some sort."

"Is wireless telegraphy a trick then?" retorted the Mahatma. "If so, then yes, so this is. Only this is as far in advance of wireless telegraphy, as telegraphy is in advance of the semaphore. This is a science beyond your knowledge, that is all. Name another city."

"Timbuctu," I said suddenly; and nothing happened.

"Mombasa," I said then, and Mombasa appeared instantly, with Kilindini harbor fringed with palm-trees.

I had been to Mombasa, whereas I never had seen Timbuctu. Almost certainly none present had ever seen the place, or even a picture of it.

The Gray Mahatma said something in a surly undertone and the golden light turned itself on again, flooding the whole chamber. King nodded to me.

"You can speak into a phonograph and reproduce your voice. There's no reason why you can't think and reproduce that too, if you know how," he said.

"Aye!" the Mahatma interrupted. "If you know how! India has always known how! India can teach these sciences to all the world when she comes into her freedom."

Throughout, the man who had admitted us had not spoken one word. He stood with arms folded, as upright as a soldier on parade. But now he unfolded his arms and began to exhibit signs of restlessness, as if he considered that the session had lasted long enough. However, he was still silent.

"Your honor is extremely clever. I've enjoyed the exhibition," I said to him in Hindustanee, but he took not the slightest notice of me, and if he understood he did not betray the fact.
