Many times it has happened that laborers have supposed that they would be great losers from the invention of labor-saving machines. Instead of this proving to be true, it would seem that laborers are benefited by the inventions. There is much evidence showing that while inventions greatly diminish the amount of labor necessary to accomplish a certain result, on the other hand they open up new lines of industry which fully compensate laborers for the loss which would otherwise fall upon them. It is to be noted also that, in our country at least, the wages of laborers have increased in the period during which labor-saving machines have been invented.
The modern sewing machine is an inestimable blessing to a family. In former days, the mother of half a dozen children would be obliged to ply the needle night after night until the small hours in order to keep her little ones properly clad. Now, with the little iron machine standing upon its small table on one side of the room, the good mother can make up the necessary garments for her children in quick time, leaving her far more hours for sleep, recreation, and social life than would be possible under the old method. Many a one can now call down blessings not only upon "the man who invented sleep," but upon the man who invented the sewing machine which gives one time to sleep.
CHAPTER VII.
THE STEAM ENGINE.
At the very summit of a mountain near Pasadena, California, stands a huge windmill, which may be seen for many miles in all directions. Here the wind blows almost constantly, and the great arms of the windmill are employed to lift water from a well in the valley below to irrigate the orange groves on the hillsides. Thus the wind has been harnessed by man to serve his purpose.
