A few interesting things to notice on this early Syllabic chart. 

1.  Long vowels are marked not by a dot-accent, but by cancelling (putting a white line through) the character.

2.  There is a distinction between short <e> and long <ē>, which does not exist in Cree (all e's are long)

3.  There is a rare <sp> syllabic series which is no longer used.
