With compound locomotives little has been done in this country. A few have

 been able to learn. It is certainly very desirable to reduce the consumption of fuel in 

 our locomotives ; but if compounding involves of necessity the use of a cranked- 

 axle, as in some examples, it can never be adopted in America, since the well- 

 known evils of that feature must far outweigh all possible gain from compound 

 cylinders. The locomotive engine is, without doubt, the most important application
