A careful account keptof all labor and material shows that the section on metal tiescost 14 per cent, less for maintenance than the correspond-ing section on wooden ties. The expense of the latter in-creased toward the end of the eight years, because some ofthe ties had to be replaced ; and this expense, it is expect-ed, will continue to increase for several years, as more newties are needed. After a service of nine years the metallic ties are, to all 26 THE AMERICAN ENGINEER [January, iSg3. .ippearances,any time atiittacliments Fig perfect, and the cnninccr in charge cannot fixwliicli tlicy will probalily reipiire renewal.
