frightened by the drag-rope, look up in astonishment and stare at the strange monster, not knowing whither to turn in flight from such a menacing apparition. How the strange monster was a few hours later within a hair’s breadth of burying us in the waves of the Baltic Sea is another story.... [Illustration: _C. G. Schillings, phot._ THE SUMMIT OF MOUNT ’NGAPTUK, ABOUT 6,000 FEET HIGH. THE CLEARNESS OF THE AIR MAKES IT LOOK AS IF THE ASCENT COULD BE QUICKLY MADE, BUT IT IS A WORK OF SEVERAL HOURS. I CLIMBED IT IN 1899--THE FIRST ASCENT BY A EUROPEAN. IN THE RAVINE RUNNING UP ON THE LEFT I FOUND SEVERAL ELEPHANTS. IN THE DRY SEASON THESE HILLS ARE THE RESORT OF NUMBERS OF RHINOCEROSES.] How many hundred times, after I had gone back to the Dark Continent, have I wished for such a lofty observatory, an airship that would bear me over velt and desert, and from which I could fathom all the secrets of the animal world of the tropics, instead of having to travel toilsomely, fettered to the earth, often merely making step after step automatically in the blazing heat of the sun. When one day such a wish as this is fulfilled, that animal world in its beauty and splendour will have to a great extent passed away.... I must, therefore, content myself with lofty observatories of another kind, that are not unfrequently to be found in the Masai uplands, in the form of numerous hills and rock masses. These afford splendid views and pictures of the animal creation to the spectator who waits patiently on their summits for hours and days, and has the help of good optical instruments. What life and activity displays itself there before our eyes under favourable circumstances! Though the wilderness may appear a desert solitude, bare and empty of all life, let only a few hours go by and the sun change its position a little, and already one sees movement under the trees and bushes that have been till now casting deep shadows. Then with measured steps, prudently regardful of their safety, all kinds of animals come forth to graze. We see the different wild species appearing, at first a few individuals, and soon in greater or smaller herds.
