Donald Walker, Walker's manly exercises (1855)
“ It is with coach-horses as with mankind—that where the physical strength is in the governed, they must be humoured a little. When starting, the coachman must not pull at their heads, but feel their mouths lightly, or they may bolt, throw themselves down, or break through their harness. If they are old, and the stage commences with a descent, they should be allowed to go a couple of hundred yards before they are put to their usual pace. A young horse should be started very quietly, making the old horse take collar first. ”
