Dignified.

Anderton, Three Bulls, Sitting on an Eagle Tail Feathers, Crowfoot,  and Red Crow at Fort Walsh, 1884

Joy was a word that belonged to the Indians.  Life was rich, and the Indians were only very stoical and sullen in the presence of whites during the war and reservation period.  They were really a happy, delightful people, so ready to laugh an amusing incident or a clever joke that they reminded the early white visitors of children at play.

In his manner and bearing, the Indian is habitually grave and dignified, and in the presence of strangers he is reserved and silent.
