On the inside of the rail for the first half mile, the vitrified brickused on Wabash avenue, with corner cut off on a sloping angle, were usedto give flange space, and between the ends of the brick, asphalt was usedin the regular way On the last mile the merits of the Havdenvilleblocks having been brought tu our attention it was decidtd 10 ii^e them.

This track andasphalt paving are bt^autiful in finish, and of unusual strength andsmootliness. It is a genuine pitasure for passengers to ride over thistrack, for there is no motion perceptible, except the forward motion. Our next experience with T rail construction was during the year1S93, in several streets paved with brick. The rail was 60-pound shang- hai, and rail plates, bond wire and supplementary wire were the same asin the street laid in asphalt.
