Jason Elmer Hammond, Suggestive programs for special day exercises… (1898)
“ Birds are singing in the trees, Tra, la, la! Tra, la, la! Boughs are swaying in the breeze, Tra, la, la, la, la! The skies are clear, the skies are blue, Tra, la, la! Tra, la, la! The trees and flowers are drest anew, Tra, la, la, la, la! Their sweetest songs the birds now trill, And brooks go tumbling down the hill; To the woods now haste away, Tra, la, la! Tra, la, la! This is happy Arbor Day, Tra, la, la, la, la! —Journal of Education. This work was published before January 1, 1928, and is in the public domain worldwide because the author died at least 100 years ago. ”
