They hurried on. "Where are Kalfastoban's quarters?" asked Tarzan. "I do not know. In Trohanadalmakus warriors are detailed to the quarries for but short periods and do not transfer their quarters or their slaves during the time that they are there. I do not know the custom here. Kalfastoban may have finished his tour of duty in the quarries. On the other hand it may be for a long period that they are detailed for that service and his quarters may lie on the upper level of the quarry. We shall have to inquire." Soon after this Tarzan stepped up to a warrior moving in the same direction as he and Komodoflorensal. "Where can I find Kalfastoban Vental?" he asked. "They will tell you in the guard room, if it is any of your affair," he replied, shooting a quick glance at the two. "I do not know." After that they passed the fellow and at the first turn that hid them from him they increased their speed, for both were becoming suspicious of every least untoward incident, and their one wish now was to escape the quarry in safety. Nearing the entrance they attached themselves to a column of slaves toiling upward with their heavy burdens of rocks for the new dome, and with them they came to the guard room where the slaves were checked out. The officer and the clerks labored in a mechanical manner, and it appeared that it was to be as easy to leave the quarry as it had been to enter it, when the officer suddenly drew his brow together and commenced to count. "How many slaves in this crew?" he asked. "One hundred," replied one of the warriors accompanying them. "Then why four guards?" he demanded. "There are but two of us," rejoined the warrior. "We are not with them," Komodoflorensal spoke up quickly. "What do you here?" demanded the officer. "If we can see you alone we can explain that quickly," replied the Trohanadalmakusian. The officer waved the crew of slaves upon their way and beckoned to Komodoflorensal and Tarzan to follow him into an adjoining chamber, where they found a small anteroom in which the commander of the guard slept. "Now," he said, "let me see your passes." "We have none," replied Komodoflorensal. "No passes! That will be difficult to explain, will it not?" "Not to one of your discrimination," replied the prince, accidentally jingling the golden coins in his pouch. "We are in search of Kalfastoban. We understand that he owns a slave we wish to purchase and not being able to obtain a pass to the quarry in the short time at our disposal we ventured to come, upon so simple an errand, without one. Could you direct us to Kalfastoban?" Again he jingled the coins. "I shall be delighted," replied the officer. "His quarters are upon the fifth level of the Royal Dome upon the central corridor and about midway between the King's Corridor and the Warriors' Corridor. As he was relieved from duty in the quarry this very morning I have no doubt but that you will find him there."
