Wait a minute, wait a minute! I goofed!

The basic strum is not Burl Ives basic. What Guthrie is doing on this bit of tablature is the basic Carter Family strum.

Maybelle Carter would play a bass string with her thumb, then brush her index finger down across the treble strings and then flick it back up again, so she got a sort of "Bump-Diddy, Bump-Diddy" rhythm. With this as her basic strum, between picking her bass notes judiciously (and even coming up on the treble strings with her thumb sometimes) and adding hammer-ons and pull-offs, she could get pretty close to playing the melody line of a song while accompanying it with chords at the same time.

You can hear examples of this on any Carter Family recording, and at least on her first LPs, Joan Baez used this style to accompany several songs. Woody Guthrie used it a lot.

I hope this helps.
