From Rand, McNally & Company, Map-makers and Publishers, Chicago:
"As to the source of the Mississippi, we gave it considerable attention in preparing our new map of Minnesota, and finally fixed it as Lake Glazier. This, we consider, has the best claim."
From George F. Cram, Map and Atlas Publisher, Chicago:
"I mail you to-day a copy of the corrected map of Minnesota, showing Lake Glazier as the source of the Mississippi."
From Matthews, Northrup & Company, Art Printers, Buffalo, New York:
"We regard Lake Glazier as the true source of the Mississippi, and are so showing it on all maps, etc., issued by us."
