The sun was low when they woke. They watched it dip below the hills, and then, after waiting until it began to get dusk, started for the valley. No one was to be seen on the road, and they ran rapidly down the slope, until they reached the heap of boulders. Surajah tore off a strip of cotton, six inches long by an inch wide, from the bottom of his dress, went forward to the stream, and wetted it. When he came back, they squeezed the moisture from it, broke up a cartridge, rubbed the powder into the cotton, and then rolled it up longways.
"That will be dry enough, by the time we want to start," Dick said. "I hope we sha'n't have to use it, but if there is no other way, we must do so."
They remained where they were, until they thought that the garrison of the fort would be, for the most part, asleep. Then they crossed the stream, and walked along by the side of the road, taking care not to show themselves upon it, as their figures would be seen for a long distance, on its white, dusty surface. Presently, the sides of the valley approached more closely to each other; and, just where they narrowed, they could make out a number of dark objects, which were, they doubted not, the houses occupied by the garrison. They at once took to the bed of the stream, stooping low as they went, so that their bodies would be indistinguishable among the rocks.
They could hear the murmur of voices, as they passed through the village. Once beyond it, they entered the gorge. Here there was but room enough for the road and the stream, whose bed was several feet below the causeway. A few hundred yards farther, the gorge widened out a bit, and in the moonlight they could see the wall of the fort stretching before them, and a square building standing close to it.
"That is the guard house, no doubt," Dick said, in low tones. "It is too close to be pleasant, if we have to attack the sentry."
Very carefully, they picked their way among the rocks, until close to the wall; then Dick gave a low exclamation of disappointment. The stream ran through a culvert, some twelve feet wide and ten feet high, but this was closed by iron bars, crossing each other at intervals of only five or six inches, the lower ends of the perpendicular bars being fixed in a stone dam, extending across the bed of the stream. Dick waded across the pool formed by the dam, and felt the bars, but found them perfectly solid and strong.
"It is no good, Surajah," he said, when he returned. "There is no getting through there. There is nothing for it but the gate, unless we can find the steps up to the top of the wall, and get up unnoticed. Then we might tear up our sashes longways, knot them together, and slip down.
"The first thing to do is to have a look round. I will get up close to the wall. It is in shadow there."
Entering the pool again, he climbed up the steep bank, which was here faced with stones. He stopped when his eyes were above the level, and looked round. There was the gate, twelve feet away, and to his delight no sentry was to be seen. He was about to whisper Surajah to join him, when he heard voices. They came from above, and he at once understood that, instead of a man being posted behind the gate, two were on guard on the wall above it. He beckoned to Surajah to join him, and when he did so, whispered what he had discovered.
"If the gate is only barred, we are all right now, Surajah; except that we shall have to run the risk of being shot by those fellows on the wall. We shall be a pretty easy mark, on that white road by moonlight. Our only plan will be to keep close to the wall, when we are through the gate, get down into the bed of the stream again, and then crawl along among the rocks. The bottom will be in shadow, and we may get off without being noticed. The only fear is that we shall make a noise in opening the gate.
