Railroad passengers arg frgqnentl! surprised by the unexpected entrane' into tAA cars of . sroup of anatteriug bareheaded women. Those who do. no recognize them as car cleaners ant clusters wonder who they are and how they boarded the train. The womer usually appear several blocks. from the terminal station. and 50 proficient art they in the art of "hipping,' a tcalr that,the engineers do not come, to afss, stop when they see their feather dust CTS and their brooms beside the track but reduce their speed somewhat, ant the women swing on as neatly as brake men. When the last passenger has, Jeff the train the women take possession ol the .cars.. They are healthy and mus. cular, quick with the broom and active with feather duster and chamois skin and by the time the cars are thrown oi the cleaning switch they have the floors well cleaned of peanut shells, paper and cigar stubs, and are ready for the sea, cushions. ..
 On some of the roads the women still carry the cushions outside of the car and beat the dust from them by whip. ping them with willow beaters. But compressed air has taken the place of the paddle on most of the roads. The hose which contains the compressed air is run into the car window or door, and the women. handling it as they would garden hose sprinkling the grass, turn the jet of missing air upon the plush cushions and the dust flies out. No whisk broom, willow paddle, leather strap, or beater can get at the dust as compressed air does. The jet search es every crack and cranny and drives the dust from the wood itself. Some times the women turn the air upon the window castings and in a jiffy 1t is clean of dust. ..-.
 The man who makes air compressors cited this novel use of compressed air as another point In favor of the claim made by his craft that compressed air was just beginning to enter into the common everyday work of the world. rJa aadAd +Jo+ fauu ,,orsore Lpn1,y %1, a uses to which compressed air was put outside of stopping trains drilling rock and inflating bicycle tires.
 "Electricians think that this Is the electrical age" he said. "Well, perhaps 1t is. so far as lighting, telephoning. teIegraphing and yielding goes, hut when 1t comes to the transmission of power they are talking too much. They have worked and studied for years to make an electric rock drill which would take the place, of the air drill. but they have not succeeded. They have tried to make an electric train brake which would bring limited express to a full stop sooner than the automatic air brakes will do 1t, but they are so far be-
  hind that they will never catch up. It will not be long before street cars will be running with compressed air as the motive power. and they will be safer, more easily controlled will,run as fast, will stop quicker. will weatslpnger, and will be operated At les expense than the best electric system hey can put on rails.
