19.13 Junior Lab Solution

You might think, because of the odd appearances of punctuation within words, that this is a keyboard change puzzle (like QWERTY-Dvorak) but it is just an arbitrary cryptogram in which punctuation is encoded just like any other letter. The key below was in the provided solution, with quirks: Cipher a, supposedly encoding underscore, is not used in the puzzle, q represents itself, and no character represents v. The puzzle appears to have an uncorrected error, that w's are used instead of s's to encode what ought to be an ellipsis at the end of the message.

Key:
