The feldspar and the mica, for example, as well as the schorl, are found variously coloured in different granites, and coloured in various proportions.

Do the neighbouring rocks of mica-slate and gneiss contain veins? or is the gold disseminated here, as in the granites of Guadarama in Spain, and of the Fichtelberg in Franconia, throughout the whole mass of the rock? Possibly the waters, in filtering through it, bring together the disseminated grains of gold; in which case every attempt to work the rock would be useless.

The rocks chiefly are gneisses, granites, metamorphosed marbles, quartzites, and slates, all of them far too old to bear fossils or coal. "Git up, pup! you've scrouged right in hyur in front of the fire. You Dred! what makes you so blamed contentious?"

"Then shall the taint of sin be purged from the earth, for every temple and pest-hole of Satan, including this whole Wizard City, will be consumed by an awful fire whose lurid light will glimmer long after the metals and granites of this great Tower shall have been reduced to ashes amidst the general ruin."

This divide, also called the Jayb el Sa'luwwah, with granites to the east, and traps mixed with granites on the west, shows signs of labour. Hard by, to the south-west, some exceptionally industrious Bedawi, of the Jerafin-Huwaytat, had laid out a small field with barley.

Granites, slates, lavas, limestone, iron ores, quartz veins, auriferous gravels, remnants of dead fire-rivers and dead water-rivers are developed here side by side within a radius of a few miles, and placed invitingly open before the student like a book, while the people and the region beyond the camp furnish mines of study of never-failing interest and variety.

To what extent some of the metamorphic rocks containing the same minerals as the granites may have been formed by hydrothermal action without the intervention of intense heat comparable to that brought into play in a volcanic eruption, will be considered when we treat of the metamorphic rocks in the thirty-third chapter. Porphyritic granite.

The sandy and stony maritime region, the foot-hills of the Ghats, granites and traps with large veins and outcrops of quartz; and Wadys lined with thick beds of conglomerate. 2. The Jibal el-Tihamah, the majestic range that bounds the seaboard inland, with its broad valleys and narrow gorges forming the only roads. 3.

The accumulations along the coast of Florida are composed chiefly of coral sand, mixed of course with the remains of the animals belonging to that locality; those along the coast of the Southern States consist principally of loam, which the rivers bring down from their swamps and low, muddy grounds; those upon the shores of the Middle States are made up of clay from the disintegration of the eastern slopes of the Alleghanies; while those farther north, along our own coast, are mostly formed of sand from the New-England granites.

One would not expect this colour either, which, nevertheless, is that of all the sands and all the granites of Egypt and Arabia. And then too, the eyes of the statue, how often have we not seen them? And did we not know that they were capable only of their one fixed stare?
