It will be noticed that aconsiderably larger and longer boiler is used on these enginesthan on the tandem-compounds, and still the heating surface issomewhat less. In the tandem-compounds 507 2-in. tubes arecarried in a 77-in. boiler, while in these engines there are only458 2-in. tubes in an 80-in. boiler; this cannot help but favorthe steaming qualities of the boiler, and is commendable prac-tice. The following ratios and dimensions furnish a basis for com-parison with other engines: Ratios. Heating surface to volume of cylinders = Tractive weight to heating surface = Tractive weight to tractive effort = Tractive effort to heating surface r= Heating surface to grate area ;= Tractive effort X diameter of drivers, to
