“Why don’t I slow it now? you will say. Well, because I found the smaller and quicker battery put on, although the other was there: why was it put on unless to use all possible speed? I cannot but think that Leäfar considers the prospect of pursuit so great that speed is in his view the first necessity. I may be wrong, but, somehow, this view of the case makes me unwilling to slow the machinery.” “I think you are right,” I said; “still it is quite possible that there may be nothing in it. The workers whom Leäfar employs may have been simply bidden to secure the batteries, and to put one of them on; the difference between the batteries may have been altogether overlooked.” “It may be so,” he said, “and one must not overlook the possibility, but I don’t think it likely.” “Then you see something in the presence of the larger battery?” “That’s it,” he said. “If only the voyage to the wire were in view a second one of the smaller batteries would have given us an ample margin for contingencies. I think that the chance of our overshooting the wire has been reckoned upon, and for that reason the other battery has been provided. The smaller battery wastes in less than twenty-four hours, the other lasts, I believe, about four weeks. But the speed of the larger is not much more than half the speed of the smaller. Now, if we do overshoot the wire, a spare battery of the smaller kind would fail us in the midst of the bush, while the larger one would enable us to reach some settlement. “Just one word more. We are now at full speed, and I found the machinery fixed for full speed when we came on board. Besides, the wind has not in any way changed since the middle of the day, and it is full in our favour now. Our speed is at the very highest, and whosoever put in the battery must have known that it would be so; even if the wind were to fall the difference would not be very great. Now, what do you say?” _Easterley._ I think we must go as we are going until dawn of day anyway. If we are not pursued before then, we shall not be pursued at all. _Wilbraham._ Why do you think that? _Easterley._ It seems to be the way of these fellows to keep as clear of civilised men as is consistent with the pursuit of their malevolent purposes. _Wilbraham._ What do you suppose to be their motive?
