"Our cornet had a telegram this afternoon," one of them said, "that we were to be specially vigilant here, and we must keep a sharp lookout at night. I don't suppose they are on this side of the river. They may be going to pull up the railway, or blow up a culvert somewhere between this and Barberton. Four men with their Kaffirs might do that, but they certainly could not damage this bridge." At ten o'clock most of the party retired into a small shed a few yards away, but two remained sitting by the fire, and were evidently left on guard, for they kept their rifles close at hand. The lads now crawled away some distance, and then made their way down a steep bank to the river. It was a stream of some size, running with great rapidity, and it did not take them long to decide that it would be impossible to swim out with the cases and place these in such a situation that the explosion would damage the structure. They then moved quietly up to the spot where the end of the last span touched the level ground; it rested upon a solid wall built into the rock, and ran some forty feet above their heads. They were now just under where the Boers were sitting, could hear their voices, and see the glow of their fire. They were unable to make out the exact position of the girders, but they had, when watching it, obtained a general view of the construction. It consisted of two lines of strong girders on each side, connected by lattice bars, with strong communications between the sides at each pier. The depth of the girders was some twenty feet. After cautiously feeling the wall and finding that there were no openings in which their explosives could be placed, they crawled away noiselessly, ascended to the bank again a couple of hundred yards from the bridge, and returned to their camping ground. They observed as they went that there were still fires burning in the station yard, that some Kaffirs were seated near these, and as, in the silence of the night, a faint sound could be heard like that of a distant train, they had no doubt that they were waiting up for one to arrive. Indeed, before they had reached the camping place they saw a train pass by. It had no lights save the head-lights and that of the engine fire, and they therefore had no doubt that it was another train with stores. When they reached their tents they had a long consultation. No fire had been lighted. The horses had been taken some way up a little ravine down which a stream of water trickled; here the four natives had taken up their post. These had only come down in the middle of the day to fetch their food, which Jack cooked over the spirit stove. This was alight when the lads returned, but was carefully screened round by blankets so that not the slightest glow could be seen from a distance. "What do you think of it, Chris?" Brown said.
