"Polly says she has, but we have never seen one," replied Anne, eagerly. "Well, Oak Creek is going to have its annual fair, or celebration, two weeks from Monday. It generally lasts for three days, and they have all sorts of stunts there. You-all must be _sure_ to go." "The Boss says we can have a day off and go, too!" declared Jim. "I wish it would happen to come on the day you girls go," added Kenneth, anxiously. "We'll try and plan it that way. Maybe we will go to each day's show," quickly said Eleanor. "Maybe you can find out from Mrs. Carew what day her husband thinks we can have," ventured Jim, in a whisper. Eleanor nodded; then she turned to John and told him what they wanted to know from Mrs. Carew. Thus it was learned that the survey Crew was to be given Tuesday _and_ Wednesday--as it would take almost half a day to travel to Oak Creek, and another half day to get back to camp. The boys gave a wild hurrah when they heard this good news, and immediately planned to start from camp directly after midnight Monday so as to enjoy a full day at the fair. After good-bys were said, and the Pebbly Pit party were ready to start on the homeward trail, Jim whispered to Polly and Eleanor, "Now don't forget! Ken and I have a date with you two at the Fair, Tuesday and Wednesday." And the girls laughingly promised to make a note in their social calendar book. The two weeks intervening between the visit to Buffalo Park, and the celebration at Oak Creek, passed rapidly, for John and Tom had a new excursion planned for each day. Of course, Polly and Eleanor were members of these picnics, so they almost forgot about the fair until a day, or so, before the time. "We-all attend the fair, you know, and take our camp outfit with us," said Mr. Brewster, at supper on Sunday evening. "Aren't there any restaurants where we can dine?" asked Barbara. "Well, there is Snake-Bill's place where you get hash piled up with your pie and odds or ends, all on an inch-thick dish. Then there is the Rocky Mountain Cafie--as every one calls it,--but ladies are not welcome, there. Neither of these places will appeal to you girls, Ah'm sure," explained Sam Brewster. "Oh, no! They have no idea of what it is like, Sam," declared Mrs. Brewster, holding up both hands in horror at the very idea. "Will we start early in the morning?" now asked Eleanor, wondering if they would be on time to keep their engagements. "Oh, we will leave here about one or two o'clock," replied Mr. Brewster, nonchalantly. "One or two!" cried Barbara, aghast, thinking he meant A. M. "Yes, then we will arrive about four or five. By the time we have the tents pitched and everything in tip-top working order, it will be suppertime. There won't be so much going on the first night, you know, but we will be there for Tuesday's early games." "Oh, my goodness! You don't mean we shall camp over night?" exclaimed Barbara.
