"The freezers?" he asked; "the freezers--oh, yes, they are all ready. At least I suppose they are, they've been standing so long. I've been having a great time with old _Silver_ in the stockade!" "Well," said Mildred, doubtfully, "if you've been off on one of your treasure trips, I don't know whether the freezers will be ready or not." But when they looked inside, there was the thick frost all over the tin. "Perfect!" said Mother Blair. "Now you will see how quickly the cream will freeze. It makes all the difference in the world whether or not it is ice-cold inside." Then they poured in the cream and shut the freezer tightly, and Jack began to turn the handles, first of one and then of the other, with "Treasure Island" open before him on an upturned pail, though he very soon found that the freezers needed all his attention. He was devoting himself to his task with grim determination when Mildred peeped in at the door and stood watching him for a moment before she asked, mischievously, "And what is old _Silver_ doing now, Jack? I believe you're really going to deserve those three plates of ice-cream, after all." "Come, Mildred!" called her mother, "we will make something perfectly delicious to drink," and she handed a fresh receipt to the girls. GRAPE-JUICE LEMONADE 4 lemons. 1 quart of water. 2 large cups of sugar. 1 quart of grape-juice. 1 orange. Put the water and sugar on the fire and boil them two minutes. Roll the lemons and squeeze the juice; when the water is cool, add this and stand it away till you need it. Then add the grape-juice, and put it in a large bowl with a good-sized piece of ice; slice the orange very thin and cut into small pieces and add last. Serve in glass cups. "That is so easy anybody could make it," said Brownie. "I guess I'll make some for us all on the next hot night." "Oh, goody!" said Mildred. "Think how lovely it would taste out on the porch just before bedtime!" "Specially if there was a moon," said Brownie. "Yes, indeed! especially if there was a moon! You won't forget, will you?" Brownie promised faithfully she would not. By the time this was done and ready to put away in the refrigerator to get very cold, Jack was shouting for somebody to come and see if the cream was frozen. "It turns awfully hard," he complained, rubbing his arms.
