dust was eliminated, and in rainy 
weather the road stayed hard, dry and 
free from mud. This condition pre- 
vailed for a period of ten months be-

of wear. Prior to the oil treatment 13 
cubic yards of sweepings were taken

after the treatment there was not more 
than cubic yards removed in the 
same period, making a saving of about 
63 per cent in the wearing surface of 
the road. In a period of ten months this 
meant the saving of about three-quar- 
ters of an inch of the road wearing sur-

every four years would be about 27 
cents per square yard, during which 
time the road would be either dusty or 
muddy, and uneven. The oil treatment 
cost cents per square yard.
