We visited the plant and had the
process carefully and infinitely ex-
planned to us.
1t is possible that this creo-resinate
treatment, as it is called, may be
more slippery in the heat of summer
than blocxs treated with Greodone or
Creoline, OF some other creosote oil
without the resin-since the resin
would exclude to some extent and
cover the surface-yet this presence
of resin at any other season of the
year would tend to roughen the sur
face and make it less slippery.
We have very few sweaty days, and
even though On such days wood block
pavement would be Objectionable,
coming so seldom, We could either
avoid them, or go over them eau
tiOusly; and as the autimobile be-
comes more universal, such objections
would be entirely eliminated.
| On our trip through the Central
West we heard no such criticism.
There the Kreodone Wood Blocks
were used.
! In Toledo, in company with Mayor
James G. Woodward, Alderman HOl
land and Councilmen Wikle and Bow
en-, we inspected several streets so
paved, and spent some time with the
workmen engaged in the actual work
of putting down the pavement We
examined shavings and pieces of many
thousands of blocks used herein, and
every one examined were thoroughly
iimpregnated with the Greodone oil
pores absolutely filled.
| One of the pavementS we examined
had been down five years and had
been subjected to heavy traffic, yet
not a sign of wear did we discover
not even the blocks around manholes
and catch basins showed any wear
land not a block was the least out of
position, except an occasional block
adjacent to the curbs had been squeez-
led up about one-fourth inch by the
pavement expanding slightly, and on
this street they had made no provi-
sion for expansion.
On all future pavements they had

There is nothing complicated or

treatment Of the blocks, or the laying
of the pavement.

The blocks should be sawed uniform

icylinder is closed and the blocks are

one hour. to sterilize and dry the
wood. Pressure up to ninety pounds
per square inch is gradually applied
for two hours and the heat raised to

The heat is gradually reduced ir

Heat is further reduced and pressure
