THE DUST PROBLEM SOLVED 
'The problem of suppressing road dust is now receiving the attention of the best engineers 
and road makers in all civilized countries. The suppression of this nuisance has become a 
necessity, for not only does it damage crops and decrease real estate values but it is a menace 
to health itself. 
Various methods have been tried for suppressing dust including sprinkling roads with 
'fresh water, treating them with calcium chloride, impregnating the road surface with crude 
oils of various kinds, etc., but all of these methods have fallen short of their purpose. 
Within the past two years, following some experiments by French engineers, this com- 
pany introduced Tarvia, a special tar preparation. The results from this treatment have been 
unusually successful. Some 800,000 yards of macadam roads were treated in about thirty 
different cities. This included work at Jackson, Tenn., under the supervision of the United 
States Department of Agriculture and work on New York roads under the supervision of the 
State Boards. It was absolutely demonstrated that Tarvia not only suppresses dust but adds 
materially to the durability of the road. It has been demonstrated that its use reduces the 
wear on the road itself about one-half, and in this way the treatment practically pays for itself. 
To anyone interested we will gladly send booklet showing numerous roads which have 
been tieated with full data covering the^subject. ’
