snobbish about spelling

It's unclear to me whether the offending passage is original to Glick or whether Glick is merely quoting George Washington. If the latter I would cut him a little slack in the spelling department; they weren't as nit-picky in those days. Even if the former I would be hard pressed to discount such a long passage on the basis of two misspellings/typos which could easily have been introduced anywhere in a long line of writing/proofreading/copy-editing.
