 is his regular routine and he has hard work keeping up

 great amount of coal, and wonders why he does not get 

 better results. 



Before leaving him let us take a look at his firebox, 

 and we will see that it is full of coal, at least up to the 

 level of the door. We will also see quite a pile of ashes
