On the level a fair pace can be maintained, but up hill no merciful man will ever press his beasts. When a heavy load has to be drawn up a sharp short hill, it is not a bad plan to cheat the horse out of the first half of it by going at it with an impetus, suffering the pace to merge into a walk without further pressure as the first impetus declines.
When the ascent is long and gradual, horses should be allowed to walk the whole way, which can always be admitted of on ordinary roads, where the pace is not intended to exceed eight miles an hour, as the speed may be accelerated when the fall of ground is reached, without distressing the animals.
Let a man suppose himself to be obliged to wheel a hand-cart with a heavy burden for a given distance within a given time, on an undulating roadway, and he will soon discover the course he would pursue to effect his object; he would certainly save himself by going very slowly up the hills, and make up the time and distance with most ease by rolling the vehicle at a rapid rate down the declivities. Let the principle of working thus exemplified be always applied to the usage of horses in harness.
An old driving maxim may be added, though not recommended by the metre:—
“Up the hill spare me;
Down the hill let me run and bear me;
On the level never fear me.”
Or,
