Hygienic Importance of Dustless Conditions 

 in Scliool Buildings 



The problem of preserving hygienic conditions in school build- 

 ings is one that deserves the serious attention of those responsible 

 for the health of pupils under their care. 



Ample ventilation and scrupulous cleanliness are vital, but 

 unless the floors receive proper attention and treatment the dust 

 that accumulates will be a constant menace, for dust is recognized 

 as the greatest carrier and distributer of disease-germs known. 



A simple yet effective treatment of floors is found in 



STANDARD 

 FLOOR DRESSING 



— a preparation that accomplishes its purpose by catching and 

 holding all dust particles and killing millions of disease-bacilli 

 coming in contact with it. Then, again, Standard Floor Dressing 

 preserves the floors by preventing them from cracking and 

 splintering. It makes the wood last longer and reduces the 

 labor and cost of caretaking. 



Three or four treatments a year are all that are necessary.
