"Well," Mr. Roberts said, "I fear there is no doubt that there are blacks about, and from the uneasiness of the animals I should say there are a good number of them. However, we are warned, and I think that the surprise will be on their side and not on ours. We removed all the bars, so the animals can get away if they like. Also, I have locked the door of the stable. Except for the uneasiness of the animals we saw no signs of the enemy at all. Now, the first thing to do is to get the shutters closed." This was at once done. Mr. Roberts had always been a little nervous of trouble with the blacks, so in addition to building his house of solid logs he had had strong loopholed shutters arranged on all the windows of the lower story, which when closed were held in their position by massive cross-bars. They discussed the best position for each to take in case of attack, and having arranged this, one of the men went up to keep a look-out from the upper windows, while the rest of the party remained chatting in the sitting-room. "I wish there was a moon," Mr. Roberts said; "it is so dark that we shall be firing quite at random." "Could we not make some sort of a torch," Effie suggested, "that would light up the place outside?" "That is a first-rate idea, Effie; but how are we to manage it?" The party sat silent for some minutes, then Effie said: "There is plenty of wool. How would it be to make a bundle of it about as big as my head, wind it round with wire, then soak it in paraffin. When the natives come we have only to put a match to it and throw it outside." "Very good indeed, Effie," her father said; "let us try to carry out the idea at once, and as all the materials are to hand it will not take us long." In half an hour six of the balls were finished. Each had a short length of wire by which it could be thrown through the window. Fortunately there was plenty of paraffin, and a bucket being filled with it, the balls were soaked one after another, and were then carried upstairs each in a separate basin. "We shall have to be very careful how we throw them," Mr. Roberts said, "or else we shall be setting ourselves on fire. Thompson, you are, I think, the worst shot of the lot, as you are rather short-sighted. I will therefore trust this business to you. Have an old blanket ready to beat out any of the burning oil that may drop on the floor. Be careful also to keep as much in shelter as possible, some of the blacks are sure to have bows ready." "All right, boss! you need not fear, I will look out. Now, as I am to be on duty upstairs, I might as well go up at once and send James down. I think, boss, you had better take post at the loopholes now, you may catch sight of one of the varmints against the sky-line. I will throw a ball as soon as I hear the first shot."
