"Cranberry Bogs" song is in the DT with two slightly different lyrics, both credited to the same source, Barney Reynolds of Mather, Wisconsin. Geographical place name "Mather" is correct in one version. The name "Mercer" is used in the other which is not correct. Mather, about 100 northwest of Madison is in a major Wisconsin cranberry growing region. Mercer, on the other hand is way up near the Michigan border, not far from Ironwood. That area was known from mining, then logging, but not agriculture.
