"But I'm not hot now," said Davy. "There's a fine breeze, and I like to sit here and talk." So they talked on about the different kinds and classes of plants, and by and by when big Prue found them, little Prue had much to tell her about all the new things she had learned. And she was careful not to pronounce anything wrong, and to explain that an Exogen was a plant that grew on the outside, and that an Endogen was another plant that grew on the inside, and big Prue said that Davy must be an Exogen, because he was getting so fat, and that little Prue must be an Endogen, because she was growing so smart. Then everything had to be told over, and then it was tea-time, with a dainty table all spread under the arbor, and delicious raspberries, and very, very delicious ice-cream. III I DON'T SEE WHAT WEEDS ARE FOR, ANYWAY AND the very next day was Fourth of July, with all the fire-crackers and torpedoes and sky-rockets that always come on that day. But there was something else. For when big Prue and the Chief Gardener come to the breakfast-table, they found that Davy and little Prue had arranged what Prue called a "susprise." The room was all red, white, and blue--not with flags or bunting, but with flowers. There were bowls of red and white and blue morning-glories on the sideboard, and in the center of the table there was a very large bowl of red, white, and blue sweet-pease, so nicely arranged that each color was separate, and the whole looked like a cake of flowers cut in three equal parts. And there were other red and white and blue flowers, too, but the sweet-pea bowl in the center was the finest of all. There was not much gardening that day, of course, for there were parades to see and music to hear, and fireworks in the evening. The Chief Gardener had brought home the fireworks, and when all the rockets had been fired and the Roman candles, he brought out something larger than the rest, and when it was lighted, it all at once turned into a great flower-pot and sent out hundreds of the most beautiful fiery flowers, such as no garden would grow, no matter how hot it was. "That is to pay for the sus-prise you gave us this morning," said the Chief Gardener, when little Prue was through dancing and squealing and jumping up and down with delight. "They grew in that hot sun yesterday." But little Prue didn't believe it, though she did ask if some of the stars which came out of the rockets didn't stay in the sky with the other stars. She was quite certain she had never seen so many in the sky before.
