From the library
A bridge spanned it midway and from there to its lower end, where an amber-hued belt of sand-hills shut it in from the dark blue gulf beyond, the water was a glory of many shifting hues--the most spiritual shadings of crocus and rose and ethereal green, with other elusive tintings for which no name has ever been found.
There, on a table, surrounded at some distance by a large and luxurious divan, every species of tobacco known,—from the yellow tobacco of Petersburg to the black of Sinai, and so on along the scale from Maryland and Porto Rico, to Latakia,—was exposed in pots of crackled earthenware of which the Dutch are so fond; beside them, in boxes of fragrant wood, were ranged, according to their size and quality, puros, regalias, havanas, and manillas; and, in an open cabinet, a collection of German pipes, of chibouques, with their amber mouth-pieces ornamented with coral, and of narghiles, with their long tubes of morocco, awaiting the caprice or the sympathy of the smokers.
