Nature was here something savage and awful though beautiful. I looked with awe at the ground I trod on, to see what the Powers had made there, the form and fashion and material of their work. This was that Earth of which we have heard, made out of Chaos and Old Night. Here was no man’s garden, but the unhandseled globe. It was not lawn, nor pasture, nor mead, nor woodland, nor lea, nor arable, nor waste land. It was the fresh and natural surface of the planet Earth, as it was made forever and ever.

— Thoreau, The Maine Woods

Unhandseled means untouched, or pure, but has the sense of being unchristened, or even unblessed, since a handsel is a gift you give to kick off a new enterprise. Unspoiled; virgin.
