Across the main range, Van Reenen's is the largest and best known pass.

The old farmer who gave it the name is living there still and bitterly laments the chance of war.

But there are other passes too, any of which may suddenly become famous now--Olivier's Hoek, near the gigantic Mont aux Sources, Bezuidenhaut, Netherby, Tintwa, and (north of Van Reenen's) De Beer's Pass, Cundycleugh, Muller's, and Botha's, beyond which the range ends with the frontier at Majuba.

Three or four of these passes are crossed by waggon roads, but Van Reenen's has the only railway.

The frontier, marked by a barbed wire fence across the summit of the pass, must be nearly forty miles from Ladysmith, but from the cliffs above it, the little British camp can be seen like a toy through this clear African air, and Boer sentries watch it all day, ready to signal the least movement of its troops, betrayed by the dust.
