Abate the Dust Evil 



It has been proven beyond a shadow of doubt that many diseases of 

 school children can be traced directly to the dusty condition of schoolroom 

 floors. Dust carries the germs of disease. The constant changes of classes and 

 the ever moving feet of the pupils cause the dust to rise from the floor and cir- 

 culate through the air. Proper ventilation aids materially in getting rid of dust, 

 but so long as the floors remain dry and untreated the danger will still exist. 



Hygienic conditions and dustless schoolroom floors can be had at small 

 cost. By treating floors three or four times a year with 



STANDARD 

 FLOOR DRESSING 



dust can be practically eliminated. Experience proves that Standard Floor 

 Dressing reduces dust over eleven-twelfths; so that with dust abated and the 

 atmosphere cleansed the chances for contracting disease are reduced propor- 

 tionately. 



Standard Floor Dressing not only makes sanitary schoolrooms, but also 

 preserves the floors. Prevents them from cracking and splintering and at the 

 same time lessens the cost and labor of caretaking. 



Standard Floor Dressing is sold everywhere in barrels, half-barrels, and 

 in one gallon and five gallon cans. 



Not intended for household use.
