Note 147 — {188} CHAPTER IX {VII}

A series of erroneous dates begins here. The expedition undoubtedly left Platte Cañon July 8, of which day the text gives no account. July 9 was Sunday, instead of July 10, as the text states below. A compensating error is introduced by giving the date July 12 to accounts of the journeys of parts of two days. The Philadelphia edition also has the erroneous dating of the ninth, tenth, and eleventh, but includes the remainder of the chapter under the last date, thus failing entirely to account for the twelfth, and really including the operations of three days (tenth, eleventh, and twelfth) under date of July 11. The itinerary for these days is more accurately indicated on the map.—Ed.
