TO HARNESS IN GARRISON, WHEEL. =Collar.=--Each wheel-driver puts on and locks the collar of his off horse. =Pad.=--He puts on the hair-pad, and also the saddle-cloth if it is to be used. If the saddle-blanket is used instead of the hair-pad, it will be folded and put on as described. =Saddle.=--He puts on the saddle, with its attachments, taking care not to displace the pad or blanket, adjusts and secures the girth, buckles the collar-strap to the saddle, and then adjusts the breeching and buckles the crupper. =Traces.=--He takes the traces from the peg, passes them through the loin-loops, attaches the rear ends to the single-tree, which is hanging on the cantle-hook, and then the front ends to the collar, beginning with the off trace; the near trace will be laid on the saddle while attaching the other. =Bridle.=--He puts on the bridle and secures the coupling-rein to the manger. He then passes the reins through the roller. =Collar.=--Each wheel-driver begins to harness his near horse, as prescribed for harnessing the off horse, at the command "_Collar_." =Pad, etc.=--Same for the near horse as for the off horse, omitting the directions for the coupling-rein and roller. =Yoke.=--The wheel-driver puts on his leg-guard, and then, going to the front of his horses, backs them out of the stall, places them side by side, facing the exit, and beginning with the off horse attaches the near yoke by means of the breast-straps, then passes the martingales between the fore legs and through the standing loop on the cincha, and attaches the hooks at the end of the side-straps to the martingale D ring, and then stands to horse. To back out his pair, the wheel-driver unfastens the coupling-rein, then stands with his back to the manger, takes the reins of the near horse in his right hand and those of the off horse in his left hand near the bit, and backs the pair into the gangway. In single stalls, separated by partitions, each horse must be backed out by himself.
