Obser-vations in reference to the heat in the rheostatwere made, although no temperatures were taken,and no difference could be observed in referenceto the heating of this portion of the explanation will be found in the compara-tively small amount of current as seen above, andthe relative infrequency of its application, and fact that the brakeshoes are being constantly be-smeared with .sandand grit thrown fi-om thewheels, and when in this condition
