In addition to the Kimberley district this territory included that part of the diamondiferous area which had been claimed by the Transvaal, but which had been declared, as the result of the arbitration of R. W. Keate, lieutenant-governor of Natal, part of Waterboer’s land.

I rather incline to the latter theory, and believe that, like the Kimberley ‘pipe,’ as diggers call it, the diamondiferous earth had been shot upwards funnel-wise from below, and that ages of floods and rain-washing had cleansed and left bare the gravel and stones upon the surface.

During 1909 various companies were formed to exploit the diamondiferous area.

Water is kept flowing into the tub through one opening, as the diamondiferous soil is worked in through another.

“The mine is thought to be the ‘pipe’ of an extinct volcano, and it is supposed that the diamondiferous soil containing garnets, ironstone, crystals, and diamonds, has been thrown up by the action of the great heat of this volcano,” replied Donald, “and there seems to be no end of the glorious riches of this bed of diamonds.”
