followed. But in the course of about two hundred days, the internal combustion was overmastered for lack of fuel; the chemical combinations, which might have gone on for ages causing weak but incessant outbreaks, were completed and their power exhausted.
This source of disturbance extinguished in the reign of the twenty-fifth predecessor of my royal patron, the construction of the great Observatory on Ranelca was commenced. A very elaborate road, winding round and round the mountain at such an incline as to be easily ascended by the electric carriages, was built. But this was intended only as a subsidiary means of ascent. Right into the bowels of the mountain a vast tunnel fifty feet in height was driven. At its inner extremity was excavated a chamber whose dimensions are imperfectly recorded in my notes, but which was certainly much larger than the central cavern from which radiate the principal galleries of the Mammoth Cave. Around this were pierced a dozen shafts, emerging at different heights, but all near the summit, and all so far outside the central plateau as to leave the solid foundation on which the Observatory was to rest, down to the very centre of the planet, wholly undisturbed. Through each of these, ascending and descending alternately, pass two cars, or rather movable chambers, worked by electricity, conveying passengers, instruments, or supplies to and from the most convenient points in the vast structure of the Observatory itself. The highest part of Ranelca was a rocky mass of some 1600 feet in circumference and about 200 in height. This was carved into a perfect octagon, in the sides of which were arranged a number of minor chambers—among them those wherein transit and other
