in particular places that these ridges can be crossed. Generally the road leads through gaps, and winds around the sides of the mountains; and, even at these places, is steep and difficult.
The rocks and cliffs of the mountains are principally grit, or free-stone; but in several places, particularly towards the foot, the slate and lime-stone predominate. Through the Glades, the slaty schist and lime-stone is abundant. On Laurel Hill, and the mountains westward of that, the fossil coal (Lithanthrax) abounds, and lies so near the surface that it is discoverable in the gullies of the road, and among the roots of trees that have been overthrown by the wind. {26} Thursday, April 14
Now that we have crossed all the mountains, the gradual and easy slope of the ground indicates to us that we are approaching those vast savannas through which flow "the Western waters." The plain expands on all sides. The country assumes a different aspect; and even its decorations are changed. The woods are thick, lofty, and extremely beautiful, and prove a rich soil. A refreshing verdure clothes the open meadows. The banks of the brooks and river are enamelled with flowers of various forms and hues. The air, which before was cold and raw, is now mild and warm. Every breeze wafts a thousand perfumes, and swells with the gay warblings of feathered choristers.
"Variæ, circumque supraque,
Assuetæ ripis volucres et fluminis alveo,
Æthera mulcebant cantu, lucroque volabant."
The painted birds that haunt the golden tide,
And flutter round the banks on every side,
Along the groves in pleasing triumph play,
And with soft music hail the vernal day.
