Where the ties arelocated, a trench is excavated 4K ins. below the tie and about 12ins. in width, and is filled with concrete, the remainder of thepavement being on a 6-in. concrete base. Under the whole is a4-in. layer of stone chips. Drain tile is laid parallel with thetrack and connected with the sewers. The paving is laid upon acushion of sand i in. in depth. In brick or asphalt paving theconcrete is carried slightly above the base of the rail. Since 1897,when this construction was first tried, we have laid considerablesimilar construction with 6-in., 7-in. and 9-in. rail, in asphalt, brickand Medina stone pavements.
