A drift is really a crossing place over a river, which latter is called a sluit, if it has water in it, or a spruit if it is dry; and whether the drift is easy or difficult for wagons to cross depends on the banks and the bottom. Thus, a shallow drift gives no trouble at all; but if the banks are steep, the mules and oxen go down one side with a run, even if the brake be well screwed up on the wagons, and invariably get mixed up at the bottom, getting their legs over the traces and pole chain: or perhaps one is pulled down, when there is much confusion and delay. If the bank is very steep on the other side, fatigue parties have to come and push the wagons up by main force, or else a team of bullocks is brought from another wagon and hitched on in front of the team which is in difficulties. Even then there is more delay, as the business is to get all the thirty or thirty-six oxen to pull simultaneously; and to induce them to do this, half a dozen drivers with their enormous two-handed whips, like huge fishing rods, flog the wretched animals unmercifully, yelling and screaming all sorts of insults in Basuto at the trembling beasts. If there is mud or water at the bottom of the drift, the difficulty is increased enormously, as the banks become slippery. It is doubtful which are the worst animals to have in your wagon when crossing a bad drift, mules or bullocks. The mules generally get mixed up with the harness, but on the other hand, when once they are started pulling all together, they certainly do tug all they know, and need no more incentive than a row of men on each side of the path yelling at them. Bullocks, however, are faint-hearted and difficult to manage, as they will lie down when they have had enough of it, and nothing will induce them to pull when they think they cannot do any good. There is one good point about bullocks, and that is that if they can only be induced to lean into their yokes, all together, their enormous bulk and weight will move anything. The greatest abomination of all in a drift or on a road is sand, as that causes trouble with both mules and bullocks; and our worst drawback has been the native drivers, as, owing to the enormous number of wagons in use by the troops, the supply of good drivers ran short, and any coolie was accepted. It was the same with the conductors, or civilians in charge of wagons, who were all supposed to be experienced transport riders; but one little man confided to me that he was nothing more or less than a baker out of employment! The Boers, when trekking with their wagons under ordinary circumstances, take things very leisurely at drifts, and hitch on an extra team at once if there is the slightest sign of trouble; but this, although the best plan, wastes a lot of time, and we never had any time to spare on the march.
