The Danger of Dust in Schoolrooms 



How it Can be Reduced Nearly One Hundred Per Cent. 



DUST Danger is a real — not a theoret- 

 ical menace. Scientific research 

 J has proved that dust is the greatest 

 carrier and distributer of disease germs 

 known. It is ever present and ever active 

 — it threatens mankind everywhere — in 

 offices, stores, schools, corridors and in 

 nearly every public building. 



The Dust problem in schoolrooms is 

 one that should have the serious considera- 

 tion of every Board of Education, every 

 Superintendent of Schools, every Principal, 

 every Teacher. The elimination of dust is 

 a duty that must appeal with peculiar force 

 to those charged with the responsibility of 

 caring for the health of pupils. 



HOW DUST SPREADS DISEASE 



Disease germs multiply with exceeding 

 rapidity. A single germ falling on fertile 

 soil will, in an incredibly short space of 

 time, generate millions upon millions of its 

 kind. These micro-organisms are found 

 by the million in dust, so that every current 

 of air causes the dust to be set in circula- 

 tion, and with it the countless myriads of 

 living germs that are such a menace to 

 health. 



The remedy for the elimination of dust 

 is not sweeping and dusting, for such ex- 

 pedients merely start the germs afresh on 

 their aerial errand of warfare against 

 mankind. 



THE TRUE REMEDY 



The most effective method of dust pre- 

 vention is that of treating all wooden floors 

 with a suitable dressing. 



Standard Floor Dressing is the true 

 remedy for the elimination of dust. It 

 has been tested by Physicians and Educa- 

 tional Boards with the most gratifying 

 results, and reports show that it reduces 

 the percentage of floating dust jiearly one 

 hundred per cent. It is being used with 

 remarkable success in thousands of places 

 for counteracting the dust evil. Every 

 year the number of permanent users in- 

 creases, and in all cases results are ex- 

 tremely satisfying. The action is purely 

 mechanical. The application of a thin 

 coat is sufficient to keep the floor at just 

 the right degree of moisture to catch and 

 hold all dust and dirt. 



Standard Floor Dressing should be 

 applied to floors about three or four times 

 a year to get the best results ; meanwhile, 

 the floors should be thoroughly cared for, 

 so that with each sweeping the surface is 

 left perfectly clean. 



Floors treated with Standard Floor 

 Dressing present a splendid appearance. 

 The dressing acts as a preservative and 

 prevents the boards from splintering or 

 cracking. The dressing does not evap- 

 orate, and by reducing the labor of caring 

 for the floors saves its cost many times over. 



Standard Floor Dressing is not intended 

 for household use. 



We are making a remarkable offer 

 applying to schools, public buildings, 

 stores and offices. Our offer is this —
