Found some of Joseph Rock's books here in the Rock (source for Pound's "Na-Khi" imagery in late Cantos). Reading some of his late fragments (Pound's), note the New Englandy, genealogical trend (the bits about the colonial charter of Connecticut, which one of his maternal ancestors had something to do with - a Joseph Wadsworth).

Reminds me of Olson a little.

Mark Scroggins in interesting thread.
