Glinda thought over the perplexing matter for a full hour, at the end
of which time she was still puzzled how to explain it. But although
her instruments and chemicals were gone, her KNOWLEDGE of magic had
not been stolen, by any means, since no thief, however skillful, can
rob one of knowledge, and that is why knowledge is the best and safest
treasure to acquire. Glinda believed that when she had time to gather
more magical herbs and elixirs and to manufacture more magical
instruments, she would be able to discover who the robber was and what
had become of her precious Book of Records.

"Whoever has done this," she said to her maidens, "is a very foolish
person, for in time he is sure to be found out and will then be
severely punished."

She now made a list of the things she needed and dispatched messengers
to every part of Oz with instructions to obtain them and bring them to
her as soon as possible. And one of her messengers met the little
Wizard of Oz, who was seated on the back of the famous live Sawhorse
and was clinging to its neck with both his arms, for the Sawhorse was
speeding to Glinda's castle with the velocity of the wind, bearing the
news that Royal Ozma, Ruler of all the great Land of Oz, had suddenly
disappeared and no one in the Emerald City knew what had become of
her.

"Also," said the Wizard as he stood before the astonished Sorceress,
"Ozma's Magic Picture is gone, so we cannot consult it to discover
where she is. So I came to you for assistance as soon as we realized
our loss. Let us look in the Great Book of Records."
