"Not now. You have heard about those that will be most likely to attract your attention, and when you can name them, they will introduce you to all the rest of their relations."
"It is a great family," said Rap, who was sitting thinking. "Big birds and little, plain gray and brown, or red, blue, and yellow—some like warm weather and some want it cold." "Speaking of cold, I wonder what became of the ice that Dodo saw Mammy Bun cracking this morning?" asked the Doctor, looking at Olive. "The very word has a pleasant sound, for it seems to me to be growing warmer and warmer."
"Toot! toot! t-o-o-t!" squeaked a tin horn across the field from the direction of the farmhouse.
"What's that?" said Nat, jumping up; "it's the dinner horn, and it can't be dinner-time."
"Not more than eleven o'clock," said Rap, looking at the sun after the fashion of those who spend much time out of doors.
"I know what the horn means," said Olive. "It means that the cake, that Nat said Mammy Bun was going to bake with the ice, is done!"
"But that was only nonsense, you know," said Nat. "Ice won't bake anything!"
"Perhaps not, but ice can freeze something, if you mix salt with it, even on this warm day, and the horn means that mammy has a tin pail full of ice cream, waiting for some one to eat it! Ice cream, made with fresh strawberries! Don't break your neck, Nat!" For Nat had dashed off so quickly that it was no use for Dodo and Rap to try to keep up with him.
