Thataway is the one that took me back a bit. In NZ we generally pronounce it these days more like 'zataway' with a voiced th as in the, or as is now quite common exactly like a z so the is pronounced like za with a very short z, whereas thence and thither (from the line in the poem) are the same th as in thorn. So by the looks of the rune poem, thence and thither are pronounced in America more like the th in the, ie voiced?
