Iron parts when rusted should be cleaned with kerosene, wiped dry, and then have applied a light coating of asphaltum paint; allow it to dry and then apply a second coat.
In the field there will not usually be much time or many materials for cleaning harness. Rust should be cleaned off ironwork with sand and then it should be oiled. Leather work should be kept soft and pliable. First remove the mud and dried sweat with as little water as possible and then work in a little oil or soft soap.
INSTRUCTIONS FOR DRIVERS, ETC.
The carriage-mule is always the leader when packing, or on the near side in draught. This mule should therefore be the most tractable and intelligent.
The mule-driver is at the left of and near the head of his mule.
If the leader is well trained and intelligent it is better to let him have his head, the driver taking place abreast the saddle.
In saddling, the driver should make sure that the hair lies fair on the mule's back under the blanket; that the blanket is properly folded; that the saddle is securely girthed, and the load evenly balanced and firmly lashed.
When on a march, as soon as it is time to feed in the morning, rub off the animal's back until the hair lies smooth; place the blanket well forward on the withers and draw it back until in proper position. Saddle, drawing the cincha half tight, and feed. After feeding, and when ready to pack, draw up the cincha.
During packing and unpacking the driver should never leave the mule's head.
