Half-way across we stopped to let our horses dip their noses in the cool water dashing merrily over the stones. Fatima only played with it, swashing her muzzle well, and flinging the bright drops over mademoiselle's horse, who drank steadily. The opposite bank was more heavily wooded, and I became aware, as I sat idly flecking the foam from Fatima's flanks with my riding-whip, that I had for some time been hearing a whippoorwill calling and its mate replying. The woods looked dense enough to be the haunts of the lonely birds, but, nevertheless, I felt uneasy and began to listen—for rarely, indeed, does one hear a whippoorwill in the daytime. I knew birds well, and I soon became convinced that these whippoorwills were like none I had ever heard. They were too deliberate in their calls and replies, and the varying number of each sounded like a system of signals. I began to wish mademoiselle had not been so tardy in starting, that we might have had company on our way, and I strained my ears if I might hear anything of Yorke, who should be not far behind.

But there were no signs of Yorke; and mademoiselle's horse had finished drinking, and there was no excuse for our delaying longer. I would not alarm mademoiselle with my suspicions, yet I wanted my firearms ready to my hand. I drew my pistol from its holster and laid it across my saddle-bow, saying carelessly that if I caught a glimpse of that whippoorwill in the woods I should shoot it for my aunt in Paris, who was making a collection of American birds.

Mademoiselle Pelagie accepted my explanation without comment, and I led the way up the steep bank opposite. Once up, I saw, to my satisfaction, that the path was still wide enough for two. I put mademoiselle on the side nearest La Petite Rivière, and I rode next the woods; and though mademoiselle had suddenly grown talkative, and was full of a saucy French wit, I fear I must have seemed very stupid to her, for all the while I was trying to keep up my share of repartee and quip I was listening, listening. Mademoiselle noticed at last that I was somewhat distrait.

"Why do you keep your eyes turned upon the woods, monsieur? In France we are taught that it is polite to look at a lady when she speaks."

"Pardon, mademoiselle," I stammered. "I am looking for that whippoorwill."

"Your apology is more than sufficient, monsieur," in her haughtiest tones. "There will, no doubt, be no other opportunity so suitable for adding to your aunt's collection."

I had kept my eyes fixed on the woods even while speaking to her, not daring to turn them away, but at her tone I turned quickly toward her.

"Pardon, mademoiselle la comtesse," I began saucily, but went on seriously. "Permit me, I beg, to seem rude, though it is farthest from my desire to appear so. It is more than the whim of my aunt that is at stake. Some day I will explain to you."

Even as I spoke I was startled by a sharp crackle followed by a stealthy rustle, as if some one had inadvertently stepped upon a dry twig and had then glided quickly away. I turned at once to the woods, and could almost have sworn I caught a fleeting glimpse of a copper-colored hand, and the flash of a rifle-barrel. But as I gazed longer I saw nothing but the dense foliage of the low scrub-oaks that grew under the tall forest trees, and I hoped I was mistaken.

A level bit of road stretched ahead of us.
