At every step we took inland the conviction forced itself upon us that we were in a country differing essentially from any hitherto visited by civilized men. We saw nothing with which we had been formerly conversant. The trees resembled no growth of either the torrid, the temperate, or the northern frigid zones, and were altogether unlike those of the lower southern latitudes we had already traversed. The very rocks were novel in their mass, their colour, and their stratification; and the streams themselves, utterly incredible as it may appear, had so little in common with those of other climates, that we were scrupulous of tasting them, and, indeed, had difficulty in bringing ourselves to believe that their qualities were purely those of nature. At a small brook which crossed our path (the first we had reached) Too-wit and his attendants halted to drink. On account of the singular character of the water, we refused to taste it, supposing it to be polluted; and it was not until some time afterward we came to understand that such was the appearance of the streams throughout the whole group. I am at a loss to give a distinct idea of the nature of this liquid, and cannot do so without many words. Although it flowed with rapidity in all declivities where common water would do so, yet never, except when falling in a cascade, had it the customary appearance of _limpidity_. It was, nevertheless, in point of fact, as perfectly limpid as any limestone water in existence, the difference being only in appearance. At first sight, and especially in cases where little declivity was found, it bore resemblance, as regards consistency, to a thick infusion of gum Arabic in common water. But this was only the least remarkable of its extraordinary qualities. It was _not_ colourless, nor was it of any one uniform colour--presenting to the eye, as it flowed, every possible shade of purple, like the hues of a changeable silk. This variation in shade was produced in a manner which excited as profound astonishment in the minds of our party as the mirror had done in the case of Too-wit. Upon collecting a basinful, and allowing it to settle thoroughly, we perceived that the whole mass of liquid was made up of a number of distinct veins, each of a distinct hue; that these veins did not commingle; and that their cohesion was perfect in regard to their own particles among themselves, and imperfect in regard to neighbouring veins. Upon passing the blade of a knife athwart the veins, the water closed over it immediately, as with us, and also, in withdrawing it, all traces of the passage of the knife were instantly obliterated. If, however, the blade was passed down accurately between two veins, a perfect separation was effected, which the power of cohesion did not immediately rectify. The phenomena of this water formed the first definite link in that vast chain of apparent miracles with which I was destined to be at length encircled. CHAPTER XIX.
