The following lines provide direct characterization in this novel:
1. Endowed with commonsense, as a massive and hard as blocks of granite
2. On the score of delicacy, or any scrupulousness which a finer sensibility might have taught him, the Colonel, like most of his breed and generation, was impenetrable.
3 - (I am not sure about this one though) - fastened together by stern rigidity of purpose
