Describe Loo and the country round it.

From the text:

For a native town it is an enormous place, quite five miles round, I should say, with outlying kraals projecting from it, that serve on grand occasions as cantonments for the regiments, and a curious horseshoe-shaped hill, with which we were destined to become better acquainted, about two miles to the north. It is beautifully situated, and through the centre of the kraal, dividing it into two portions, runs a river, which appeared to be bridged in several places, the same indeed that we had seen from the slopes of Sheba's Breasts. Sixty or seventy miles away three great snow-capped mountains, placed at the points of a triangle, started out of the level plain. The conformation of these mountains is unlike that of Sheba's Breasts, being sheer and precipitous, instead of smooth and rounded.
