Jeanne says: My Grandmother Delia Blythe is on the end right, third person down from the top.  It appears she has a bow or something in her hair and has a scarf or ascot around her neck.  From family history, I know she attended summer school at Cassville during 1907 or 1908 to obtain a second or third grade teaching certificate so assume this was one of those years.

From Jane Kay (Foland) Poore:  In the third row back, the woman in white on the left end is my grandmother, Leland Jane Jordan.  The gentleman next to her is my grandfather, Earl Lee Smithson.  Jane Jordan graduated from Cassville High School in April 1907.  She was teaching school when she married my grandfather on 26 Dec 1908.  So, I can't pinpoint it any closer than Jeanne has.
