A very different character marks the next in importance of the mountain-formations that belong to the district of Freeland--namely, the Aberdare range, about forty-five miles west of the Kenia, and stretching from north to south a distance of more than sixty miles, with an average breadth of twelve and a-half miles. The highest peak of this chain reaches nearly 15,000 feet above the sea; and while the Kenia everywhere bears an impress of grandeur, a ravishing loveliness is the great characteristic of the Aberdare landscapes. It is true that here also are not wanting colossal hills that produce an overwhelming impression, but the chief peculiarity is the charming variety of romantic billowy-outlined hills, intermingled with broad valleys, covered in part with luxuriant but not too dense forests, in part spreading out into emerald flowery pastures everywhere watered by numberless crystal-clear brooks and rivers, lakes and pools. This mountain-district of nearly 800 square miles resembles a magnificent park, from whose eminences the mighty snow-sea of the Kenia is visible to the east, and the emerald-and-sapphire sheen of the great Masai lakes--Naivasha, El-Meteita, and Nakuro--to the west. And this marvellously lovely landscape, which combines all the charms of Switzerland and India, bears in the bosom of its hills immense mineral treasures. Here, and not at the Kenia, as our geologists soon discovered, was the future seat of the Freeland industry, particularly of the metallurgic industry. Beds of coal which in extent and quality at least equalled the best of England, magnetite containing from fifty to seventy per cent. of iron, copper, lead, bismuth, antimony, sulphur in rich veins, a large bed of rock-salt on the western declivity just above the salt lake of Nakuro, and a number of other mineral treasures, were discovered in rapid succession, and the most accessible of them were at once taken advantage of. In particular, the newly opened copper-mines had a heavy demand made upon their resources when the telegraph was laid to the coast; the demand was still heavier as electricity became more and more largely used as a motive force.
