L. Frank Baum

“ Glinda, the Good, in her palace in the Quadling Country, had many things to occupy her mind, for not only did she look after the weaving and embroidery of her bevy of maids, and assist all those who came to her to implore her help—beasts and birds as well as people—but she was a close student of the arts of sorcery and spent much time in her Magical Laboratory, where she strove to find a remedy for every evil and to perfect her skill in magic. ”

“ Glinda found the Scarecrow playing croquet with Trot and Betsy Bobbin, two little girls who lived at the palace under Ozma's protection and were great friends of Dorothy and much loved by all the Oz people.
"Something's happened!" cried Trot, as the chariot of the Sorceress descended near them. "Glinda never comes here 'cept something's gone wrong." ”

“ Glinda reflected earnestly on this information and decided that someone must go to Ozma's assistance. While there was no great need of haste, because Ozma and Dorothy could live in a submerged dome a long time, it was evident they could not get out until someone was able to raise the island. ”
