The rear pair act chiefly as a yielding cushionwhich does not come into play until the front springs have donetheir work.

It is often many years before iron or steel framework showssigns of deterioration from rust or age, but once the processof decay sets in, unless it is promptly arrested, it spreads withlightning rapidity. A case in point is that of some steel cars which were boughtby a prominent concern about eight years ago for gravel servicein contract work. They passed into the hands of a railroadcompany later on and were used in coal, gravel and cinderservice. Two years ago the cars looked well, showing but fewsigns of the rapid deterioration which subsequently recent examination of the cars showed that they had so de-cayed as almost to necessitate rebuilding. For instance, the beams had rusted away on each side so that there were holesclear through the upright part, while the tap of a hammer onthe bottom or sides of the cars would put more holes in framing if exposed to the drip
