From Rev. Andrew D. Stowe, Rector, Trinity Church, Anoka:
"This is to certify that from the testimony of Indians and Half-breeds living at White Earth Agency, Minnesota, during my residence there of two years, I am persuaded that Lake Glazier, instead of Itasca, is the real source of the Mississippi."
From D. Sinclair, Winona:
"In the autumn of 1862 I spent several weeks in that portion of Northern Minnesota, extending from Crow Wing to Leech Lake, and the country about Red Lake, in company with Paul Beaulieu, the well-known Indian guide and interpreter. During a conversation as to the source of the Mississippi, Beaulieu informed me that Lake Itasca was not the real source of that river, but that a smaller lake, located a short distance south of Itasca, was entitled to that distinction. After investigating the matter recently, I have no doubt of the genuineness of Captain Glazier's claim to be the person who first publicly established the fact that the lake which now bears his name is the true source of the Mississippi River."
From William A. Spencer, Clerk United States District Court, Saint Paul:
"I have resided in Minnesota upwards of thirty years, and until recently have always thought that Lake Itasca was the source of the Mississippi; but after an examination of the claim of Captain Glazier to be the discoverer of the true source, I am satisfied his claim is well founded."
