Driving a pair is much the same as driving one horse; but allowances should be made for the peculiarities of each, and they should not be treated as though machines of identical construction.
Frequently a woman driving a nervous horse with a quiet one will hit them both with the whip, when, should she touch the quiet one only, the sound of it would urge the other as much as the blow does the dull one.
Here is another objection to clucking to horses: one of them needs it much more than the other, yet they hear it with equal clearness, and simultaneously; therefore the high-mettled horse increases his pace sooner and more than his sluggish companion, and does more than his share of the work. Several noiseless touches of the whip, administered in quick succession to the laggard, will do more to equalize their pace than would a sharp, loud cut or any amount of clucking.
Sometimes a woman will experience great inconvenience from not having her horses properly bitted and harnessed. This should always be seen to, either by herself or some one who is competent to judge for her. When she has more than one horse to control, she will soon become tired if one of them pulls and the other will not go into his collar.
A judicious readjustment of the curb-chain and the coupling-rein will often make the difference between discomfort and ease.
