The Boer territory extended a few miles beyond this. Komati-poort was close to the frontier. As they knew nothing as to the construction of the bridge beyond the fact that it was iron, and were not even sure whether it was entirely on Boer ground, or if the eastern bank of the river here belonged to the Portuguese, they decided that at any rate it was better to travel as near the frontier as possible, as, were they pursued they could ride at once across the line. Not that they believed that the Boers would respect this, but they would not know the country so well as that on their own side, and would not find countrymen to join them in the pursuit. Keeping down on the eastern side of the hills, they continued until they could see the white line of steam that showed the direction in which a train from the south-east was coming, and were therefore able to calculate within half a mile where the bridge must be situated. They camped in a dry donga, and next morning at daybreak left their horses behind them in charge of the men and walked forward. A mile farther they obtained a view of the bridge. It stood at the point where the river, after running for some little distance north-west, made a sharp curve to the south. The bridge stood at this loop. If the object had been to render it defensible, it had been admirably chosen by these Boers who laid out the line to the Portuguese frontier, for from the other side of the bank the approach could be swept by cannon and even musketry on both flanks. Lying down, they took in all the details of the construction through their glasses, and then, choosing their ground so that they could not be seen by any on the bridge, they kept on until they were able to obtain a view from a distance of a quarter of a mile. The examination that was now made was by no means of a satisfactory nature. Near the bridge there were sidings on which several lines of loaded trucks stood. An engine was at work shunting. At least a score of natives were at work under the direction of Portuguese, while several men, who were by their dress evidently Boers, were pointing out to the officials the trucks they desired to be first forwarded. Three or four of these carried huge cases, two of them being each long enough to occupy two trucks. "There is no doubt those are guns," Chris said. "If we can do nothing else, we can work a lot of damage here, which will be some sort of satisfaction after our long ride. As to our main object, things don't look well." Half a dozen armed Boers could be made out stationed at the Portuguese side of the bridge, and as many more at the opposite end. Two lately-erected wooden huts, each of which could give shelter to some fifty men, stood a short distance beyond the bridge, and it was evident by the figures moving about, and a number of horses grazing near, that a strong party was stationed there to furnish guards for the bridge.
