=Harness, Lead and Swing.=--The lead-and swing-drivers harness in the same manner as wheel-drivers, with such omissions as are required by the difference in the harness. The traces are passed through the loin-strap loops, the front ends attached to the collars, and they are then trussed by bringing the rear ends forward and passing the toggle through the ring. The lead and swing pairs are not turned around nor backed into the gangway after harnessing unless it is intended to lead out. TO UNHARNESS. =Unyoke.=--Beginning with his near horse, each wheel-driver detaches the hooks at the end of the side-straps from the martingale-ring and draws the martingale from the standing loop on the cincha; he then unhooks the inside end of each breast-strap, detaches the neck-yoke, and hangs it up on its peg. =Unbridle.=--He uncouples his horses, leads them into the stall, secures the coupling-rein of the off horse to the manger, unbridles his near horse, puts on the halter and ties the halter-strap to the manger, hangs up the bridle, and takes off his leg-guard and places it on the peg. =Collar off.=--He unbuckles the collar-strap, detaches the front ends of traces from the collar, removes the collar and hangs it on its peg. =Traces off.=--He unhooks the traces from the single-tree, takes them off and hangs them on their peg. =Unsaddle.=--He unbuckles and frees the crupper, disengages the girth, places the breeching and then the girth on the saddle, takes off the saddle and places it on its peg with the saddle-pad on top. =Unbridle.=--Each wheel-driver unfastens the coupling-rein, unbridles his off horse, puts on the halter, ties its strap to the manger, and hangs up the bridle. =Collar off, etc.=--The off harness is taken off in the same order as the near harness. TO UNHARNESS IN THE FIELD. =Without Harness-racks.=--The pole-prop is placed under the end of the pole; the single-trees are left attached to the double-trees; the wheel-traces are unhitched from the collars only, and laid over the chest from front to rear, or on the foot-board; the collars of the wheel-team on top of the limber-chest (paulins having been removed) next to the rail on the near side, the swing-collars in the middle, and the lead-collars next to the other rail; the collar of the off horse is placed on top of that of the near horse of the same team; the remainder of the harness is placed on the pole, that of the near wheel-horse next to the double-tree and as close to it as possible, next that of the off wheel-horse, both in the order laid down for the wheel-harness; the traces of the lead-and swing-harness (folded once) are laid over the pole; then on top of them the saddles, with the attachments over them, so as not to rest on the ground. The neck-yoke is placed on the foot-board.
