The use of glutrIn n the treatment
OF both earth and macadam roads.
while yet in the experimental stage.
has created a considerable amount Of
interest among road engineers and
the New York State Highway Depart
ment In particular. IN common with
many other preparations which have
been brought upon the market OF late
for the treatment Of road surfaces.
such as oil and calcium chloride. the
experiments, so far AZ they have gone,
while they have been more or less
successful, have not extended over 3
sufficiently long period Of time to con-
stitute q proper test
Theoretically, some of these prepa-
rations afford a solution of problem
that has become a serious one with
road engineers, since the advent OF the
automobile, says the Empire State Mo
torisI, but in most cases they have
been tried out under all conditions
and covering a sufficient length OF
time to warrant their definite CLASH
fleation In point of actual results.
Glutrln is byproduet of wood pulp.
Its real ingredients are rosin and
pitch It Is soluble IN water and when
applied diluted, naturally penetrates
the road surface upon which 1t is apz
piled. In consistency, glutrin resem-
b1es maple syrup and Is generally sold
by the gallon in Dbl. lots. In the case OF
earth roads, when applied diluted, Il
forms a crust varying In depth from
four and one-half to five and one-half
inches. Because of the penetration Il
Is absolutely impossible for water 10
get down into the road. Dew, fog.
water, and in fact moisture of all
kind, asslmilate with glutrin readily
and thus increase Its penetration.
Probably the best example of the
glutrln treated earth roads is the
stretch conducted IN the town
of Middlefleld, Otsego county, about 4
year ago, under the supervision OF tie
bureau of Town Roads OF the State
Highway Department. That expert
mental stretch Is some thirteen hun
dred feet in length and Is located in
