"That 'ere was its first name," explained Solomon knowingly. "Accordin' to them papers o' Professor 'Elmuth's, it was changed to Fort St. Thomas after its destruction. You see, sir and miss, some o' them 'ere relics belonged to Saint Thomas—Didymus, I doubt it was—and as they was never dug up again the name just stuck to the place, so to speak. This 'ere'd be the place for Jenson, Mr. 'Ammer," and he chuckled again as he laid his finger on one of the squares in the corner of the plan.

As Solomon had told them before, the fort was merely a group of buildings with a wall around, much as were the barracoons and warehouses for less valuable goods. The corner to which he pointed was that farthest away from shore, and seemed to be separated from the fort proper by the angle of the corner bastion.

"Why?" asked the girl. "What was that, John?"

"This 'ere, miss, was a little room set above the ground, according to the plan. It was a prison—them Portuguese were main cruel, which was why they didn't last—and under this 'ere room was a stone pit full o' puff-adders."

Solomon went on to say that he had not seen this room when there before, as there was too much jungle to inspect the place closely; but the text, with the plans, explained its purpose fully.

In fact, it was not until a native king had perished in this snake-pit that the place was finally attacked and razed, with the help of the fleet from Muscat which had already taken Port Jesus, or Mombasa.

Suddenly, Hammer recollected Omar's wild tales about monkeys throwing skulls at him and pits full of snakes, and related what he could of the man's story.

Solomon nodded gravely, saying that there might still be snakes there, though the monkeys were probably imagination, and fully reassured Sara Helmuth that she would be in no danger through joining his Arabs and making camp in the ruins; and, in any case, puff-adders would hardly be encountered outside the pit.

Upon which, with the air of a man who has played his part exceeding well, Solomon stated that he was in need of rest and would take a nap until the run was finished.

Hammer had seen no sign of Jenson's launch ahead, for he had no glasses, and the secretary had obtained a good start. When Solomon had curled up on the bottom beneath the thwarts the American sat beside Sara Helmuth in the stern, as they had sat on that eventful night that seemed ages ago, when Baumgardner had paid for treachery with his life.
