Not long ago I stood one day amidst the flying shuttles of 

 one of our many cotton mills, and as I looked I questioned. 

 On my left, where employees were at work, were looms cap- 

 able of yielding three hundred yards of woven fabric per 

 week. The attendant was caring for eight of these, making 

 her weekly output twenty- four hundred yards. Over on my 

 right were other looms so improved that one person could 

 care for eighteen to twenty-four, at the same output per 

 loom, making the total seventy-two hundred yards. " What 

 marks the diflference ? " we asked. " Chiefly the greater har- 

 mony in adjustment of parts and consequent reduction of 

 friction," said the official ; and then I began to hark back, as 

 the boys say. 



Later I called at one of the saw mills on our river, and as 

 I stood there watching it devour logs, I noticed over yonder 

 the old up-and-down saw working its way laboriously through 

 the logs and throwing oft* daily about six thousand feet of 

 lumber. Hard by was the gang, set at swifter motion and 

 with capacity increased to twenty thousand feet. ' On the 

 upper slip was the band saw with its musical whirr as it flew 

 on its mission with friction seemingly reduced to the mini- 

 mum, eating its way through forty-five thousand daily, and 

 saving one inch in every eight cuts. "What marks the 

 difierence?" we asked. "Harmony of adjustment and re- 

 duced friction," was the reply ; and again I harked back. So 

 through the whole field of mechanics might we wend our way, 

 finding every where the same lesson and the same experience. 



The tremendous energies of man are constantly being 

 turned to the invention of a screw, a hinge, a pivot or a 

 wheel, which will give finer adjustment, and larger as well
