On the other side we pass over masses of porphyritic trap, in contact with the same mica schists, and these probably give to the soil the great fertility we observed.

The great body of the mountains is syenite.

So much mica is washed into the river, that on looking attentively on the stream one sees myriads of particles floating and glancing in the sun; and this, too, even at low water.
It was the 15th of August before the men returned from the ship, accompanied by Mr.Rae and the steward of the "Pioneer." They brought two oxen, one of which was instantly slaughtered to put courage into all hearts, and some bottles of wine, a present from Waller and Alington.

We never carried wine before, but this was precious as an expression of kindheartedness on the part of the donors.

If one attempted to carry either wine or spirits, as a beverage, he would require a whole troop of followers for nothing else.
