On Monday the enemy betrayed signs of activity in the building of a redoubt opposite the Premier Mine. This was disappointing; it looked as if the purpose was to place a gun in the redoubt--to shy shells at the Premier. A special edition of the _Diamond Fields' Advertiser_ lent colour to the assumption. The Boers, the special stated, had a gun fixed up at Mafeking, and had actually trained it on that town. The shells, we were assured, had not burst; but (flying) they could hit a man in the head, we thought. Whence they (the Boers) got the gun was a puzzle to not a few; and how they managed to make it "speak" was beyond the comprehension of others. "They might have another gun," these people exclaimed in horror! They might indeed; the question soon ceased to be one of speculation, for when a body of the Light Horse attempted to cross the Free State border, the boom of "another gun" was unmistakably real. Shell after shell was burled at the Light Horse; none of them were hit, and not having bothered bringing artillery with them, they were unable to retaliate. Later in the day an express rider made his way through the Boer lines. The most interesting news he was able to impart was summed up in the Proclamation he carried in his pocket. It bore reference to the prohibition by the Governor of the sale of arms and ammunition throughout the Cape Colony. It was feared that the Africanders might buy the goods and throw them across the border; it had been done. But information in disproof of this was forthcoming when the story reached us that a number of the Cape Dutch had risen in rebellion and needed the weapons for themselves! Kimberley's voice at once favoured the extreme penalty--death for high treason! Even moderate men, who allowed for racial sympathies, held that neutrality was in the circumstances the proper attitude to assume. But the local extremist--and he was the man of the hour--argued that the object of the rebels was to sweep the English into the sea, and to make Africa the exclusive privilege of the Africander. In the evening, a terrific explosion was heard; a dynamite magazine had been blown up at Dronfield. It was stated that some people went up along with it; but that part of the story has yet to be verified.
