Time is measured by sensation, and with me minutes were drawn out into hours. "Surely, it is midnight. I have been here three hours at the least. The road must have forked, and I have gone the wrong way. The most sagacious of horses could not be expected to know which of two roads to take. There is nothing to be done. I am in for the night, and had better stay here than go farther in the wrong direction." I dismount, fill my pipe, and strike a light. I laugh at my thoughtlessness, and another match is lighted to look at my watch, which tells me I have been on the road precisely twenty minutes. I mount. Spitfire seems quite composed, perhaps a little astonished at the unusual conduct of his rider, but he walks on composedly, carefully avoiding the rolling stones. It is not a pleasant situation,--on a prairie alone and at night, not knowing where you are going or where you ought to go. Zimmermann himself never imagined a solitude more complete, albeit such a situation is not so favorable to philosophic meditation as the rapt Zimmermann might suppose. I employ my thoughts as well as I am able, and pin my faith to the sagacity of Spitfire. Presently a light gleams in front of me. It is only a flickering, uncertain ray; perhaps some belated teamster is urging his reluctant mules to camp and has lighted his lantern. No,--there are sparks; it is a camp-fire. I hearken for the challenge, not without solicitude; for it is about as dangerous to approach a nervous sentinel as to charge a battery. I do not hear the stern inquiry, "Who comes there?" At last I am abreast of the fire, and myself call out,-- "Who is there?" "We are travellers," is the reply. What this meant I did not know. What travellers are there through this distracted, war-worn region? Are they fugitives from Price, or traitors flying before us? I am not in sufficient force to capture half a dozen men, and if they are foes, it is not worth while to be too inquisitive; so I continue on my way, and they and their fire are soon enveloped by the night. Presently I see another light in the far distance. This must be a picket, for there are soldiers. I look around for the sentry, not quite sure whether I am to be challenged or shot; but again I am permitted to approach unquestioned. I call out,-- "Who is there?" "Men of Colonel Carr's regiment." "What are you doing here?" "We are guarding some of our wagons which were left here. Our regiment has gone forward at a half-hour's notice to reinforce Zagonyi," said a sergeant, rising and saluting me. "But is there no sentry here?" I asked. "There was one, but he has been withdrawn," replied the sergeant. "Where are head-quarters?" "At the first house on your right, about a hundred yards farther up the road," he said, pointing in the direction I was going.
