n any other way. From the outline of this bed, it struck me that Chaussures Nike Air Max TN IX Terra Ninety some natural obstacle or other had checked the detritus, brought down by the current, as sand and gravel are checked and accumulated against a log or other impediment athwart a stream, presenting a gradual ascent on the side next the current and a sudden fall on the other. Such, in truth, is the apparent form of the great fossil bed of the Murray. This idea, which Kvinnor Jackets struck me as I journeyed down the river, was strengthened, when at a lower part of it I observed a ridge of coarse red granite, running across the channel of the river, and disappearing under the fossil formation on either side of it. It appeared to me to be probable that this ridge of granite might rise higher in other places, and that stretching across the current as it did, that is to say from west to east, the great accumulation of fossil and other Naiset Cg Montebello Parka CG55 Suomi remains had Kobiety Barbour Quilted Kurtka been gradually deposited against it, forming a gradual ascent on the northern side of the ridge, and a precipitous fall upon the other.
I have already observed that at a particular point the rivers of the interior, which Dame Moncler Downy Trimmed I had traced on my first expedition, appeared to lose their character as such, and that they Menn Moncler Eric soon afterwards ceased in some extensive marsh, the evaporation and absorption over such extensive surfaces being greater than the supply of water they received. This point is about 250 or 300 feet above the level of the sea, and if we draw a line eastward, from the summit of the fossil formation, and prolong it to the western base of the Blue Mountains, Dame Moncler Bady we shall find that it will pass over the marshes of the several rivers falling into the interior, and will strike these rivers where their channels appear to fail, as if that had been the former sea-level.
The impressions I have on this interesting subject are clear enough in my own mind, but they are difficult to explain, and I fear I have but ill expressed myself so as to be understood by my readers. I only wish however to record my own ideas, and if I am in err |
