How does the Mormon/LDS Primary song "I Have A Garden" go?

I am trying to find sheet music or a recording for this song, written by Mary Hale Woolsey. I can find the lyrics, but I can't find the tune anywhere! There is a piece of the song in a play I'm working on, and it's very important that I figure out how it goes. So, if you could link me somewhere, or even record yourself singing it, that would be wonderful! The part of the song I'm looking for, specifically, is this one: "I have a garden, a secret garden where thoughts like flowers grow day by day. 'Tis I must choose them and tend and use them and cast all wrong ones like weeds away." Thank you for your help!
