A prop:rly d.;;crned aircempressor can create wh"tever vacuum is needed abcut tbe plant, as we!! as supply air at pressure. "The agination of liquids is _anorther use to which the air-jet principle has been successfully applied. Mixed paints, varnishes, and ma ay chemical and dyeing solutions must be kept in constant agitation, or very th a roughly stirred !)'•' hand or mechanical means belor? drawing. Axjemf>ressed air manifold in tb" bottom of the tank, with orifices facing downward to prevent Fodimejt. entering and stopping up the holes, is a sw?t efl'ectivo means of accomplishing this

purpose. It cm make the? liquid fair boil. '

"A blast of compressed air also is an excellent moans of blowing the factcrywhistle, if you caaTy no '.team at nigh!; or over holidays. If the air-compressor is electrically driven, it can be started and stopped automatically to replenish the air-supply si ould be whistle have to blow a lorg time. The.United States Steel Corporation at Gary have & special. dornpTessrd air whistle which they blow lour times a, day to call the attention of p?l workmen la the subject of safety."
