It cost us a fatiguing ride of nearly twelve hours' duration--most of it along by-roads and bridle-paths--at intervals passing through tracts of swampy soil, where our horses sank to the saddle-girths in mud. We rode continuously: stopping only once to recruit our horses at one of the "stands," or isolated log hostelries--which are found upon the old "traces" connecting the sparse settlements of the backwoods. It was the only one we saw upon our route; and at it we remained no longer than was absolutely necessary to rest our wearied steeds, and put them in a condition for the completion of the journey. We knew the necessity of haste. Our only hope lay in being able to reach the mouth of the Obion before the canoe could pass out of it. Otherwise, our journey would be in vain; and we should not only have our long ride for nothing, but would be under the necessity of doubling the distance by riding back again. Along the route we found time to discuss the circumstances--both those in our favour and against us. The water-way taken by the canoe was far from being direct. Both the creek and the larger stream curved repeatedly in their courses; and in ordinary times were of sluggish current. The freshet, however, produced by the late rain-storm, had rendered it swifter than common; and we knew that the canoe would be carried down with considerable rapidity--faster than we were travelling on horseback. On such roads, for so great a distance, fast travelling was impossible; and could only have been accomplished at the risk of killing our horses. Mounted as I was, I might have made more of the time; but I was under the necessity of slackening pace for my companion--whose sorry steed constantly required waiting for. Our sole chance lay in our route being shorter, and in the circumstance that the fugitives had not a very long start of us; but for all this the issue was exceedingly doubtful; and by the nicest calculations, we were satisfied we should have but little margin to spare.
