We followed them intently, and I noticed that they both kept looking up towards the top of the hill, behind the town, which I have told you was the highest point on the island. They seemed extremely interested in something there, and even stopped the boat and gazed steadily up at it through field-glasses.
They were evidently satisfied, went on again, and we saw them run alongside the Hong Lu and climb up her accommodation-ladder.
The Commander had watched them carefully through his glasses, and now I saw him earnestly searching the top of that hill.
"That explains it all," he muttered to himself, and passed them across to me. "Look under those trees."
I could see nothing at first except a great broad track running up the side as if some heavy weights had been roughly hauled up it, but looking more closely under the trees I saw crowds of Chinese working like ants, then I made out the bend of a derrick, like a single boat's davit, showing up against the sky-line.
With this to guide me, and looking very carefully, I made out a great tarpaulin or canvas, covering something. It was a huge gun.
"Now I know why they fished up the old Ting Yuen," said the Commander, "and why she has no guns. They've managed to mount one of her 12-inch guns on top of that hill, and there is another on the beach close alongside her waiting to go up too, if I am not mistaken.
"My aunt," he chuckled, "how proud our sappers and gunners would be with a job like that!"
He seemed perfectly cheerful, and chuckled merrily to himself, though, for my part, I only thought that that big gun up there made it all the more impossible to capture the island, and that lying, as we were, right in the middle of the pirate harbour on a little ledge of rock not a hundred yards away from the sentries, with no chance, as far as I could see, of escaping, was not particularly funny.
I was simply frightfully hungry and fearfully thirsty. I had sucked grass and licked wet leaves till I was nearly sick. My legs and body were so stiff that it pained me even to roll over, ever so gently, and the sun was not warm enough to dry me properly. Jones was still sound asleep, and the Commander began making more sketches of the top of the hill, peering hard through his glasses, then adding a little to the drawing, and correcting the measurements by holding the pencil up against his eyes and moving his thumb along it. He was strangely elated.
