In conclusion it may be stated that the material closely resembles 

 retort carbon, and as far as can be ascertained from small scale labora- 

 tory tests, incandescent pieces thrown out from the smoke stack of a 

 locomotive would be but little more likely to cause fires than similar 

 pieces of incandescent non-combustible material.
