Trying to track down a very old children's poem...?

My great aunt is 95 this year and she remembers part of a lovely poem from when she was a small child. As she is a poetry lover, I would really like to find the full version to give her. Can anyone help me? Obviously its very old but I have searched high and low to no avail. It starts with the lines...

"On Saturdat next at half past eight,
I musn't be half a second late,
I'm going down to the garden gate where the dew is glittery pearly..."

Thanks for any help!
