What vernacular words does Twain use in "The Celebrated Jumping Frog of Calaveras County" and how is this more authentic?

Much of the humor in Mark Twain's short story "The
Celebrated Jumping Frog of Calveras County" is result of the native dialect in which the
 "good-natured, garrulous old Simon Wheeler" tells his story to Mark Twain. The use of
the native dialect in addition to giving an authentic ring to the story foregrounds  the
native folk element of the narrative. Simon Wheeler belongs to the now defunct mining
camp of Angel's and in order to make the story as authentic and realistic as possible
Mark Twain makes Simon Wheeler speak in the native dialect of Angel
Camp.

Some examples are as
follows:

1. 'feller' instead of
'fellow.'

2. 'solittry' instead of
'solitary.'

3.  'anywheres' instead of
'anywhere.'

5.  'dangdest'   slang expressing annoyance or
dislike.
