Humphrey Milford, Oxford University Press, 1935
Small 8vo, 48pp
7 illustrations in ink (dated 1907)
This first separate edition is in The Oxford Story Readers, Second Series. Not listed in The British Library online catalogue.
The illustrations are dated 1907, and I have information this story was first published in a Mrs. Strang's Annual for Children, also published by Oxford UP, but not located as yet.
