Bouguereau William

Bouguereau William
Oz ordered the balloon carried out in front of the Palace, and the people gazed upon it with much curiosity. The Tin Woodman had chopped a big pile of wood, and now he made a fire of it, and Oz held the bottom of the balloon over the fire so that the hot air that arose from it would be caught in the silken bag. Gradually the balloon swelled out and rose into the air, until finally the basket just touched the ground

The balloon was by this time tugging hard at the rope that held it to the ground, for the air within it was hot, and this made it so much lighter in weight than the air without that it pulled hard to rise into the sky.
"Come, Dorothy!" cried the Wizard. "Hurry up, or the balloon will fly away."
"I can't find Toto anywhere," replied Dorothy, who did not wish to leave her little dog behind. Toto had run into the crowd to bark at a kitten, and Dorothy at last found him. She picked him up and ran towards the balloon.
