Keep 

 The Dust Down 



In schoolrooms and gymnasiums it is of the greatest 

 importance that everything be done to benefit the health 

 even in the smallest degree. The harmful effects of too 

 much dust in the air are well known. 



The constant shuffling of feet in the schoolroom, 

 and the more violent exercise in the gymnasium, stir up 

 dust and circulate it in dangerous quantities. It is of the 

 greatest importance to general health that the amount of 

 this floating dust should be reduced. 



MMm 



holds down all dust that settles, and prevents its circulation in the 

 air. Standard Floor Dressing is a special preparation, and vegetable 

 and animal germs cannot find subsistence in it. They are held 

 down and swept away at the end of the day. Many schools, 

 -gymnasiums and stores, where the importance of reducing dust was 

 recognized, have been quick to avail themselves of the properties 

 of Standard Floor Dressing.
