Barrett Manufacturing Co. 
Worcester, Mass., has now used 380,000 gal- 
lons of Tarvia for the preservation of its roads 
and the prevention of dust. 
The Tarvia methods were tried only after 
a prolonged and thorough investigation by the 
Mayor and the Superintendent of Streets. All 
of the street work that was done in the previous 
four years in eastern Massachusetts, both with 
Tarvia and other dust layers, was carefully ex- 
amined. 
The results of the first application of Tarvia 
in Worcester were so satisfactory that the city 
purchased several tank cars of Tarvia each week 
during the season. Practically all the new 
macadam in Worcester was constructed with 
Tarvia X, the grade recommended for new work. 
In a public statement recently, Mayor James 
Logan states, “Tarvia speaks for itself. Thus 
far it has recommended itself, and the tarviated 
streets are the best ones in the city.” No one 
who looks over the city can escape the same 
conclusion. 
A few of the streets treated with Tarvia are 
illustrated herewith. 
The advantages of the Tarvia treatment 
may be stated as follows : 
The road lasts longer. Dust in dry weather 
and mud in wet weather are abolished. Heavy 
automobile traffic wears the road but little. 
Traction resistance is reduced. Frost and snow 
do not soften the road. 
Tarvia is made in three grades : 
Tarvia X for use in road construction. 
Tarvia A for use on the surface of macadam 
roads to preserve them and keep them 
them dustless. 
Tarvia B for use as a dust suppressor.
