I wandered carelessly about, now following a bird over a rounded hill (one, I remember, was covered literally from end to end with the common brake,--_Pteris_,--which will give the reader an idea of its sterility), now keeping to the road. In such a soil flowers were naturally scarce; but I noticed houstonia, phlox, hieracium, senecio, pentstemon, and specularia. Like the brake, the names are suggestive of barrenness. The senecio (ragwort), a species with finely cut leaves (_S. millefolium_), was first seen on Missionary Ridge. There, as here, it had a strange, misplaced appearance in my eyes, looking much like our familiar _S. aureus_, but growing in dry woods! So the morning passed. The hours were far too brief, and I would have stretched them into the afternoon, but that my trunk was packed for Walden's Ridge. It was necessary to think of getting back to the city, and I took a quicker pace. Two more Kentucky warblers detained me for a moment; a quail sprang up from under my feet; and on the other side of the way an oven-bird sang--the only one found in the valley. Then I came to the car-track; but somehow things wore an unexpected look, and a preacher, very black, solemn, and shiny, gave me to understand, in answer to a question, that the city lay not where I thought, but in an opposite direction. Instead of making a circuit I had cut straight across the country (an unusual form of bewilderment), and had come to another railway. But no harm was done. In that corner of the world all roads lead to Chattanooga. A WEEK ON WALDEN'S RIDGE. I. Throughout my stay in Chattanooga I looked often and with desire at a long, flat-topped, perpendicular-sided, densely wooded mountain, beyond the Tennessee River. Its name was Walden's Ridge, I was told; the top of it was eighty miles long and ten or twelve miles wide; if I wanted a bit of wild country, that was the place for me. Was it accessible? I asked. And was there any reasonable way of living there? Oh yes; carriages ran every afternoon from the city, and there were several small hotels on the mountain. So it happened that I went to Walden's Ridge for my last week in Tennessee, and have ever since thanked my stars--as New England Christians used to say, in my boyhood--for giving me the good wine at the end of the feast.
