Wayland was sure of this a few steps farther on, when the Supervisor's horse went down in a small bog-hole, and Berrie's pony escaped only by the most desperate plunging. The girl laughed, but Wayland was appalled and stood transfixed watching McFarlane as he calmly extricated himself from the saddle of the fallen horse and chirped for him to rise. "You act as if this were a regular part of the journey," Wayland said to Berrie. "It's all in the day's work," she replied; "but I despise a bog worse than anything else on the trail. I'll show you how to go round this one." Thereupon she slid from her horse and came tiptoeing back along the edge of the mud-hole. McFarlane cut a stake and plunged it vertically in the mud. "That means 'no bottom,'" he explained. "We must cut a new trail." Wayland was dismounting when Berrie said: "Stay on. Now put your horse right through where those rocks are. It's hard bottom there." He felt like a child; but he did as she bid, and so came safely through, while McFarlane set to work to blaze a new route which should avoid the slough which was already a bottomless horror to the city man. This mishap delayed them nearly half an hour, and the air grew dark and chill as they stood there, and the amateur ranger began to understand how serious a lone night journey might sometimes be. "What would I do if when riding in the dark my horse should go down like that and pin me in the mud?" he asked himself. "Eternal watchfulness is certainly one of the forester's first principles." The sky was overshadowed now, and a thin drizzle of rain filled the air. The novice hastened to throw his raincoat over his shoulders; but McFarlane rode steadily on, clad only in his shirtsleeves, unmindful of the wet. Berrie, however, approved Wayland's caution. "That's right; keep dry," she called back. "Don't pay attention to father, he'd rather get soaked any day than unroll his slicker. You mustn't take him for model yet awhile." He no longer resented her sweet solicitude, although he considered himself unentitled to it, and he rejoiced under the shelter of his fine new coat. He began to perceive that one could be defended against a storm. After passing two depressing marshes, they came to a hillside so steep, so slippery, so dark, so forbidding, that one of the pack-horses balked, shook his head, and reared furiously, as if to say "I can't do it, and I won't try." And Wayland sympathized with him. The forest was gloomy and cold, and apparently endless. After coaxing him for a time with admirable gentleness, the Supervisor, at Berrie's suggestion, shifted part of the load to her own saddle-horse, and they went on.
