Show Man Power and Coal Power. Does any ono realize the power oi coal ns a worker? A man was eet to 1 work to pump as hard as ho could all day, and nt the end of ten hours It t was found that he had done Just as much work aa a little Icsb than two ounces of coal could do, Taking all the energy put forth by . a hard-working man during one wholo year, the same amount of force would be furnished by 3G pounds of good coal, or say 40 pounds of average coal. .. Wo produce six tons a head of population, pop-ulation, and this contnlnt the energy of 330 mon working for a whole year. Of course, even In our best engines the greater part of the working en ergy of coal Is wasted, nut even If j only one-tenth Is turnod to account, one and a half hundred weight of coal is equal to a man working for 300 , days of the year. ' A horse can do as much work aa ten men, but one and a quarter pounds of coal has as much working force as a horse exponds In one day. So that a ton of coal, If we could use all Its ' force, would do as much work as six horses working for a whole year. ,. . i ,r - . - . |
