As light is now produced, itmeans the absorption of energy and thewasting of much more. The light fromthe electric lamp represents a large wastefrom the burned fuel to the dynamo andthe conversion of the electric current intolight again is attended by an additionalenormous loss, as the greater part of itsenergy goes to producing heat instead oflight. To secure light without heat is theeffort of the electrician, but whether hisefforts are to be crowned with success isas yet uncertain. In the investigation of light, some inter-.

It may be that on some roads where it isnot the practice to plane tlie drixing boxflanges taper, as shown at D-i D-2 D-3D-4, that there is less difficulty from jour-nals wearing taper from the driving wheel. Something About Light. The only practical means known by man-kind for producing light is by raising thetemperature of some substance, usuallycarbon, to a state of incandescence whichthen becomes luminous or gives a state of incandescence is not re-quired for light giving is apparently evi-denced by the mysterious light of the fire-fly and the These insignifi- esting laws are learned regarding theluminosity of incandescent bodies. Theluminosity or light emitted by an incan-descent body like glowing carbon, is pro-portional to the fifth power of its tempera-ture. Thus the temperature of the elec-tric arc. as determined by Violle. is
