'Mid mossy banks

Figure of speech. Aping elevated (and antiquated) poetic diction, Dan Dawson's speech omits letters from many words, turning "though" into "tho'," "amid" into "'mid," "beneath" into "'neath," "over" into "o'er," and "it were" into "'twere." Rhetorical theory has many different names for such omissions, depending on where they occur in a word. All are forms of metaplasm, or changes of spelling.
