you will have to learn the clutch hy patience and 

 experience. 



But I want to say to you that the friction clutch is 

 a source of abuse by many an engineer, because the en- 

 gineer uses no judgement in its use. 



A certain writer on engineering makes use of the 

 following, and gives me credit: "Sometimes you may 

 come to an obstacle in the road, over which your 

 engines refuses to go, you may perhaps get over it in 

 this way, throw the clutch-lever so as to disconnect 

 the road wheels, let the engine get up to full speed 

 and then throw the clutch-lever back so as to connect 

 the road wheels." Now I don't thank anyone for 

 giving me credit for saying any such thing. That 

 kind of thing is the height of abuse of an engine. 



I am aware that when the friction clutch first came 

 into use, its representatives made a great talk on 

 that sort of thing to the green buyer. But the good 

 engineer knows better than to treat his engine that 

 way. 



Never attempt to pull your loads over a steep hill 

 without being certain that your clutch is in good 

 shape, and if you have any doubts about it put in the 

 tight gear pin. Most all engines have both the fric- 

 tion and the tight gear pin. The pin is much the 

 safer in a hilly country, and if you have learned the 

 secret of the throttle you can handle just as big loads
