Making use of all the cover we could, and continuing our way till Closeburn was left behind, we came out upon a narrow and unfrequented road overshadowed by beech and oak trees. The air thrilled with the song of birds, and the spirit of the hour seemed to have descended upon the packman, for as we trudged along he whistled merrily. By and by we came to the edge of a wood. Just on its margin we crossed a rustic bridge which spanned a little brown rivulet that trickled sinuously in and out between its mossy banks. Following the line of the stream we entered the wood, Hector leading the way. The ground was a great carpet of luscious green, save where it was spangled over with beds of blue speedwell. The foliage of the trees--beech, oak and mountain ash, pine and fir--broke up the rays of sunlight and the air within the wood was delightfully cool. Our path led steadily up from the bed of the stream till it looked like an amber thread meandering through a gorge a hundred feet beneath us. Here and there its course was checked by a quiet pool, so still that one might think the stream had ceased to flow; and where some branch of a bush or tree touched the surface of the water it was garlanded with a ball of tawny froth from which little flakes broke away and studded the surface of the pool like scattered silver coins. We penetrated deep into the wood--the stream chattering far below us--and at last Hector, half-turning, and saying earnestly "Tak’ tent," began to clamber down the slope towards it. I followed, and in a few moments we had reached the edge of the water. Leaping from stone to stone, Hector led the way past a waterfall upon our left which, thin as veil of gossamer and iridescent in the sunlight, fell from an overhanging rock into the burn. Just beyond us and to the right the stream issued from a defile. Above us, on both sides, the sandstone rocks towered, and looking up from the depths one could see the sky through the leafy screen of foliage that overshadowed us. Carefully choosing every footstep, we continued up the stream. The way, though difficult, seemed quite familiar to the packman.
