"All summer long these workers are laying in food to keep this large family during the cold weather. If for any reason the supply of food is low the workers sting the babies to death rather than have them starve. Is it any wonder that these workers, who have so much to do and so many cares from morning until night, die very young? The queen may live for two or three years, but the workers do not live longer than six or eight weeks." "Goodness me!" said Jimmie, "I wouldn't have believed there was any insect on the face of the earth as clever as those bees! If insects were all like that, I'd want to know about every one of them. Can't you tell us something of the wasp? They must be clever fellows, too." "Not to-day," answered Ben Gile; "it is getting toward noon, and we must start home for dinner and to get our partridge cooked. Pick up the birds, Jack, and put them in your game-bag. We must be off." XV LEAVING CAMP At last the day had come, and the children were to leave Camp-in-the-Clouds. They had been there for one whole glorious week of fishing, hunting, camping, picnicing, stories, and sleeping in tents. Betty and Jimmie felt rather sober, for the time for them to go back to the city was drawing near. A week now, and their good times for the summer would be over. Already the leaves were turning a little, and the air growing crisper every day. Indeed, up in Camp-in-the-Clouds they had twice in the early morning to break the ice on the spring in order to get the water, and at night the blankets felt warm and cosey. Betty and Jimmie liked their city home, and after they were once in it they enjoyed their school work, too. They had many friends, entertainments, parties, and made many expeditions to the Zoo and to the parks. But, somehow, the happiest days of all the year came in the summer in Rangeley Village. Every hour seemed precious to them now, and the fingers on Betty's right hand--the number of days that were left--were all too few. Even Jimmie, who cared less for the country than Betty did, was sorry. And the children were sorry to have them go. All through the cold, white winter in Rangeley Village they were expecting the Reece children and the old guide. With their coming, good times began again. And this morning, on which they were leaving camp, they felt rather blue, for, although they expected to come back the next summer, as indeed they did, yet it seemed such a long, long time to wait! They followed Ben Gile single file down the mountain at a good pace, but without saying very much. By noon they had reached the Dead River Ponds, and were ready for luncheon. "I think some of that birch, Tom," said Ben Gile, "would make a good fire for us." [Illustration: _A._ Feeding the baby wasps. _B._ A grown-up wasp.]
