“When we are in the fields, clear of the house, keep close by my side, and even try to keep step with me. What you have to say, say NOW; there must be no talking to betray our position--we must go silently, and you'll have enough to do to exercise your eyes and ears. I shall stand between you and any attack, but I expect you to obey orders without hesitation.” He opened the back door, motioned to Cato to pass out, followed him, locked the door behind them, and taking the negro's arm walked beside the low palings to the end of the garden, where they climbed the fence and stood upon the open field beyond. Unfortunately, it had grown lighter with the breaking of the heavy clouds, and gusty gleams of moonlight chased each other over the field, or struck a glitter from standing rain-pools between the little hillocks. To cross the open field and gain the fringe of woods on the other side was the nearest way to the quarters, but for the moment was the most exposed course; to follow the hedge to the bottom of the field and the boundary fence and then cross at right angles, in its shadow, would be safer, but they would lose valuable time. Believing that Cato's vengeful assailant was still hovering near with his comrades, Courtland cast a quick glance down the shadowy line of Osage hedge beside them. Suddenly Cato grasped his arm and pointed in the same direction, where the boundary fence he had noticed--a barrier of rough palings--crossed the field. With the moon low on the other side of it, it was a mere black silhouette, broken only by bright silver openings and gaps along its surface that indicated the moonlit field beyond. At first Courtland saw nothing else. Then he was struck by the fact that these openings became successively and regularly eclipsed, as with the passing of some opaque object behind them. It was a file of men on the other side of the fence, keeping in its shelter as they crossed the field towards his house. Roughly calculating from the passing obscurations, there must have been twelve or fifteen in all.
