The four young folks started on the trail that wound about the cliffs, and Mrs. Brewster went indoors to cook some old-fashioned doughnuts--a large stone crock of which was always kept in the pantry. The walk seemed very long to Barbara, who was unaccustomed to much walking, but the other three girls reveled in the exhilarating air and bright morning sunshine. Reaching the first cliffs, Polly explained about the volcanoes of that section of Colorado and showed the visitors many interesting formations of lava. They were about to continue to the Giant Guards, when Barbara complained of aching feet. She declared it was the rough trail and not her tender feet that caused the pain and ache. So the girls sat down to rest, while Polly told of trips to other volcanic craters and peaks. They were about to start on their way again, when the echoes of a lively whistle sounded over the lava walls. "It's Jeb going to the corral to find our horses for this afternoon," explained Polly, leaning out over a fragment of lava to see who was passing by. But Jeb did not pass. He called loudly for his young mistress. "Miss Pol-lee--Ah got sumthin fer you-all!" "Come up here, Jeb! We're resting on the Giant Guards!" shouted Polly. Soon Jeb appeared on the edge of the cliffs and held out a huge paper bag that had great grease-spots here and there on its sides and bottom. "Yer Maw hed me bring these dunnits t' you-all, ez Ah come by. She sez fer you-all t' let me have anudder one, too." "Oh, they are still warm!" exclaimed Eleanor, as Polly handed her one from the bag. "Shore! But that makes 'em tas' better!" declared Jeb, anxiously watching Polly hand one to Anne next, and one to Barbara, before remembering him. "They're horribly greasy things," said Barbara, holding the doughnut fastidiously with the tip ends of her fingers. "Mebbe folks'd call 'em by anudder name ef no grease war used t' cook 'em by. Ah likes 'em, howsomeever, grease an' all!" returned Jeb, grinning with relief as Polly gave him two large ones. "Um! But they're good!" Eleanor smacked her lips at the first bite. "I can't eat mine--they look so impossible!" And Barbara raised her hand and threw her doughnut over the cliff. "Oo-ah!" came from Jeb in dismay, but he hurriedly left the girls. Polly was surprised, too, but she merely said: "We never waste anything worth while. The chickens and pigs like doughnuts--if we ever have any left for them." Anne had to turn away to hide a smile, and at that moment she saw Jeb at the foot of the cliff, glancing up to see if any one saw him pick up the discarded delicacy from the ground. The incident over the doughnut silenced Polly as she led the way between the two giant peaks of lava. They reared their heads more than sixty feet high and were so oddly shaped that they derived their names of "Giant Guards" from the spears seemingly held out from the shoulders to challenge passersby.
