“I have a better plan,” said the old man. “When the smoke conceals us, follow me. There is one exit that is unguarded, probably because they do not dream that we would use it. When I passed over the dais behind the throne I took occasion to note that there were no Bolgani guarding it.”
“Where does it lead?” asked Tarzan.
“Into the basement of the Tower of Diamonds—the tower in which I discovered you. That portion of the palace is nearest to the east gate, and if we can reach it before they suspect our purpose there will be little doubt that we can reach the forest at least.”
“Splendid!” ejaculated the ape-man. “It will not be long now before the smoke hides us from the Bolgani.”
In fact it was so thick by this time that the occupants of the throne room were finding difficulty in breathing. Many of them were coughing and choking and the eyes of all were watering from the effects of the acrid smoke. And yet they were not entirely hidden from the observation of the watchers all about them.
“I don’t know how much more of this we can stand,” said Tarzan. “I have about all I care for, now.”
“It is thickening up a bit,” said the old man. “Just a moment more and I think we can make it unseen.”
“I can stand it no longer,” cried La. “I am suffocating and I am half-blinded.”
“Very well,” said the old man; “I doubt if they can see us now. It is pretty thick. Come, follow me;” and he led the way up the steps of the dais and through an aperture behind the thrones—a small opening hidden by hangings. The old man went first, and then La, followed by Tarzan and Jad-bal-ja, who had about reached the limit of his endurance and patience, so that it had been with difficulty that Tarzan had restrained him, and who now was voicing his anger in deep growls which might have apprised the Bolgani of their avenue of escape. Behind Tarzan and the lion crowded the coughing Gomangani; but because Jad-bal-ja was just in front of them they did not crowd as closely upon the party ahead of them as they probably would have done otherwise.
The aperture opened into a dark corridor which led down a flight of rough steps to a lower level, and then straight through utter darkness for the rather considerable distance which separated the Tower of Diamonds from the Tower of the Emperors. So great was their relief at escaping the dense smoke of the throne room that none of the party minded the darkness of the corridor, but followed patiently the lead of the old man who had explained that the first stairs down which they had passed were the only obstacles to be encountered in the tunnel.
