Mary was the cook, but, as she slept up on the third floor, she would hardly hear the children going out.
"Shut the door easy," said Bunny to Sue, as they reached the front steps. "Don't let it slam."
They had found the door open, as Mr. and Mrs. Brown had left it, and the two children, each taking hold of it, closed it softly after them.
"Now we're all right!" whispered Bunny, as he started down the street on the run, for the bell was ringing louder than ever now, and Bunny was anxious to see the fire, if there was one. He hoped it would not be one of his father's boats, or the office on the fish dock.
"Wait! Wait for me!" cried Sue to her brother. "I can't run so fast, Bunny, 'cause I'll stumble over my bath robe. It's awful long!"
"Hold it up, just as I do," said Bunny, turning around to look at his sister. "Hold it up, and then your legs won't get tangled in it."
Sue pulled the robe up to her knees, and held it there. Bunny was doing the same thing, the bare legs of the children showing white in the moonlight. Bunny started off again.
"Wait! Wait!" begged Sue. "Take hold of my hand, Bunny."
"I can't!" he answered. "I've got to hold up my robe, or I'll tumble and bump my nose. Besides, how can I take hold of your hand when you haven't got any hand for me to take hold of?"
That was true enough. Sue was holding up her long robe with both hands.
