To be sure, there was the reassuring fact that Hazen would or should appear within the next forty-eight hours, but it was decidedly problematical as to whether I could communicate with him or could receive any aid from the air. However, there was nothing to be done but obey and puff away at my pipe. With the idea of cutting the exhibition short I stepped closer to the throne and blew the smoke towards the faces of the king and the priest. The monarch was soon coughing and spluttering, but he was game, while the priest, to my amazement, sniffed the smoke and seemed to enjoy it. Here was trouble. Evidently he had a natural taste for tobacco and this fact caused me a deal of worry, for if the old rascal took it into his head to acquire the habit and demanded I should let him try a puff at the pipe I would be in a pretty fix indeed. However, my fears on this score were groundless, and presently the king, who could stand it no longer, signalled for me to depart, which I did most gladly. I still had it in mind to investigate the water supply, and with Zip—reminding me of an acrobatic clown—beside me, headed for the aqueduct. This I found was of stones, dovetailed together in water tight joints, and built like an open trough and the speed of the water flowing through it proved the supply well above the city’s level. It was an easy matter to follow the conduit, for a well-trodden path was beside it, but it was a steep up-grade climb for nearly a mile before I gained the spot where the aqueduct tapped the mountain rim. Here the water gushed from a hole in the solid rock and from its volume I knew it must come from some large reservoir. From where I stood I could look directly down into the quarry and the thought flashed through my mind that if the people continued to quarry in the place for many more years they would undermine and weaken the foundations of the aqueduct.
