The heatingis inversely proportional to the amount of radiating surface whichis much greater with four motors. The division of the equipmentinto four parts instead of two also reduces the strain propor-tionally on the gears, axles, bearings, thus reducing the wearand tear of these parts. The bulletin contains a list of no roads on which fourmotor equipmciUs are in service and a number of Icsfimnnialsfrom high speed railways are strongly in favor of them. Seit. i;, 1901.

Roebling, who died while the work ivas vet in progress.
