Reading edition
55. Original had "today"; changed to "to-day" to be consistent with other occurrences in the text.
56. Original had "varition"; changed to "variation".
57. Original had "Copper-Mine-River"; changed to "Copper-Mine River".
58. "S." in the latitude reading is very unlikely; almost certainly a misprint for "N."
