on the floor or i^rouiul. When leather is to be stored (jr shipped, it 

 shonld be thorou.^hly cleaned and lightly oiled on both sides. 



Metal: The metal parts of horse equipment should be kept clean 

 and free from rust. The manner of cleaning- and removing the rust 

 dei)ends upon the metal and the finish. 



Bronzed metal should not have its finish disturbed. .\ny cleaning- 

 material such as emery, sand, or brick dust, which cuts the surface will 

 destroy the bronze finish and hence should not be used. A soft i)ine 

 stick, comoline and elbow grease will remove rust without damaging 

 the finish. 



White metals are, generally, corrosive and non-corrosive. The non- 

 corrosive are easily cleaned and kept clean, but do not take so high a 

 polish as do the corrosive. The corrosive, such as steel and nickel- 

 plated, are freed from rust in ^^rious ways. The simplest way is by 

 hand with emery cloth or i^owder, or with oil and fine sand or brick 

 dust, then burnished with the chain burnisher to remove scratches and 

 restore the smooth polished surface. This however is not recommend- 

 ed for nickel plate as the plating will soon be worn ofif. It is best to 

 treat it in the same way as bronze. 



Other methods of removing rust are used and when much metal has 

 to be cleaned they will save much labor. A number of pieces can be 

 fastened together in a bunch and' dragged through sand, or they may 

 be placed in a sack and simply shaken, the difTerent pieces cleaning 

 each other. An excellent device for this purpose is a barrel or keg 

 mounted on an eccentric axle, with crank handle on the end of axle to 

 revolve it. As the barrel revolves the ends are raised and lowered alter- 

 nately and the metal within is constantly churning about. Fine sand or 

 brick dust in the barrel will greatly hasten the cleaning. .\11 the harness 

 chains of a section of a battery of Field Artillery can be freed from rust 

 in this manner within from a quarter to half an hour. The same means 

 can be used to burnish and polish, if soft material such as leather scraps, 

 sawdust, or small pieces of paper are used in place of the sand. If there 

 is much cleaning to be done it is preferable to have two barrels, one for 

 cleaning- and one for polishing. Brass is treated similarly to white 

 metal. It can be given a high finish by the use of almost any kind of 

 polish. 



Painted metal requires occasional removal of the old i)aint and re- 

 painting. The paint can be removed by the same means as rust and 

 requires less labor. All metal should be cleaned after use and then 

 wiped off with an oily rag.
