Q, thanks for the data. The Juvenile Singing School was first published in 1837, but the page number is 129. I'll post the contents of other songbooks by Mason later: Lowell Mason, The Boston School Song Book (Boston: Wilkins, Carter and Co., [1840], 1844); Lowell Mason & George James Webb, eds., The Song-Book of the School-Room (Boston: Wilkins, Carter, & Co., [1847], 1850); Lowell Mason, The Song-Garden; A Series of School Music Books, Progressvely Arranged, Bks 1-2 (New York/Boston: Mason Brothers, 1864); Lowell Mason, Mason's Normal Singer (New York: Mason Brothers, 1856). The Odeon, I think, isn't a school songbook ("designed for adult singing schools, and for social music parties").
