Such was the history given by Mokoum. He said that he thought it right to tell the Colonel the whole truth, adding, that for his own part (if the Colonel so wished) he should not hesitate to continue the march.
Colonel Everest consulted with his colleagues, and it was settled that the work, at all risks, should be continued. Something more than half of the project was now accomplished, and, whatever happened, the English owed it to themselves and their country not to abandon their undertaking. The series of triangles was resumed. On the 27th the tropic of Capricorn was passed, and on the 3rd of November, with the completion of the forty-first triangle, a fifth degree was added to the meridian.
For a month the survey went on rapidly, without meeting a single natural obstacle. Mokoum, always on the alert, kept a constant look-out at the head and flanks of the caravan, and forbade the hunters to venture too great a distance away. No immediate danger, however, seemed to threaten the little troop, and they were sanguine that the bushman's fears might prove groundless. There was no further trace of the native who, after eluding them at the cromlech, had taken so strange a part in the oryx chase: nor did any other aggressor appear. Still, at various intervals, the bushman observed signs of trepidation among the Bochjesmen under his command. The incidents of the flight from the old cromlech, and the stratagem of the oryx hunt, could not be concealed from them, and they were perpetually expecting an attack. A deadly antipathy existed between tribe and tribe, and, in the event of a collision, the defeated party could entertain no hope of mercy. The Bochjesmen were already 300 miles from their home, and there was every prospect of their being carried 200 more. It is true that, before engaging them, Mokoum had been careful to inform them of the length and difficulties of the journey, and they were not men to shrink from fatigue; but now, when to these was added the danger of a conflict with implacable enemies, regret was mingled with murmuring, and dissatisfaction was exhibited with ill-humour, and although Mokoum pretended neither to hear nor to see, he was silently conscious of an increasing anxiety.
On the 2nd of December a circumstance occurred which still further increased the spirit of complaint amongst this superstitious people, and provoked them to a kind of rebellion. Since the previous evening the weather had become dull. The atmosphere, saturated with vapour, gave signs of being heavily charged with electric fluid. There was every prospect of the recurrence of one of the storms which in this tropical district are seldom otherwise than violent. During the morning the sky became covered with sinister-looking clouds, piled together like bales of down of contrasted colours, the yellowish hue distinctly relieving the masses of dark grey. The sun was wan, the heat was overpowering, and the barometer fell rapidly; the air was so still that not a leaf fluttered.
Although the astronomers had not been unconscious of the change of weather, they had not thought it necessary to suspend their labours. Emery, attended by two sailors and four natives in charge of a waggon, was sent two miles east of the meridian to establish a post for the vertex of the next triangle. He was occupied in securing his point of sight, when a current of cold air caused a rapid condensation, which appeared to contribute immediately to a development of electric matter. Instantly there fell a violent shower of hail, and by a rare phenomenon the hailstones were luminous, so that it seemed to be raining drops of boiling silver. The storm increased; sparks flashed from the ground, and jets of light gleamed from the iron settings of the waggon. Dr. Livingstone relates that he has seen tiles broken, and horses and antelopes killed, by the violence of these hail-storms.
Without losing a moment, Emery left his work for the purpose of calling his men to the waggon, which would afford better shelter than a tree. But he had hardly left the top of the hill, when a dazzling flash, instantly followed by a peal of thunder, inflamed the air.
