Two diagrams in text. Spirited discussion of such questions as 'Is a horse-power really a horse's power?' 'I was surprised and pleased the other day to find in Marseilles that the man directing the electric tram-cars in that city corresponding to the driver of the old horse-car, sometimes called in America the motorneer, is called the wattman, and I have since learnt that this term is very general in France.'
