Arbor Day was an important day for Iowa in 1906. State administrators wanted to make the day special so that the people of the state would plant trees in their yards, parks, and near roadways. To encourage this, the State Superintendent of Public Instruction, John F. Riggs, wrote this booklet filled with short plays, tableaux, songs, recitations, and finger plays for schools' use. Bird Day is a companion holiday to Arbor Day, and is always celebrated May 4th. Arbor Day is the last Friday in April.
