That night the boys talked over all their plans. They agreed that if the next night was a stormy one they would try to rescue Mr. Roscoe. The donkey was tethered outside the tent, and seemed satisfied with his surroundings. The boys patted him and fed him on all sorts of dainties, from sugar to pancakes made from quick-raising flour.
"Might as well keep on the good side of him," observed Fenn. "He's got quite a trip ahead of him."
They decided to start off early in the morning and take the ladder to the edge of the sanitarium grounds, hiding it in the woods.
It began to rain that night. There was a regual downpour, so hard that it awakened the boys by pelting on the canvas roof over their heads.
"This is a storm, and no mistake!" exclaimed Fenn, sitting up in his cot. "If it keeps up tomorrow night we could rescue every inmate in the sanitarium."
Suddenly, above the sound of the rain, there came a startling noise. It was like the mingled roar of a lion and the snarl of a tiger.
"What's that?" cried Ned.
"It's the donkey braying!" replied Fenn, and, a moment later, when the sound was repeated, his companions knew Fenn was right.
"He doesn't like being out in the rain," Fenn went on. "I'm going to put him under the wood-tent."
This was a piece of canvas stretched between two trees and served to keep the camp wood, and some other effects, dry. Fenn put on his raincoat, slipped a pair of rubber boots on and went outside. He carried a lantern, and as soon as he emerged from the tent the donkey set up a bray that was twice as loud as the others had been.
"He's glad to see me," called Fenn, and he led the beast under the shelter. It seemed that this was what the donkey wanted, for he became quiet after that, and the boys went to sleep in spite of the noise the rain made.
It had not cleared when morning came, but they did not mind that. They all had raincoats, for Frank had not taken his to the sanitarium, and, with rubber boots, were ready to brave the elements.
Once more the ladder was fastened to the donkey's back and the boys started off. They closed the tent to keep the rain out, and put the canoe where it would be safe. They took a lunch along, for they felt they might have to undertake a longer journey than the boys had made in going to the asylum, as the animal could not follow over some of the places where the lads had tramped.
They followed, in a general direction, the telephone line. Frank told them he had learned this connected with the central exchange in Darewell, and had only been in use a short time. It had been strung by some of the asylum attendants and was a private wire.
For a while the boys trudged on through the rain, picking out the easiest paths for the donkey, which Bart was leading. Fenn walked ahead to see that there were no vines or trees that might catch the ladder, while Frank and Ned brought up in back to see that the rear end was kept clear. Occasionally they assisted in swinging the ladder around a short turn.
"This is easier than I thought it was going to be," remarked Bart. "We haven't had a bit of trouble yet."
"You're not out of the woods," called Fenn, repeating Bart's words of the day before.
They had reached a little clearing in the forest, and, as there was a good trail, the donkey increased his speed. Suddenly there came a smart shower, and the little deluge must have frightened the beast. For, as soon as the drops began to patter down on his back harder than usual, the donkey lifted up its heels, kicked the rear end of the ladder to one side, and began to run, braying loudly.
"After him!" cried Bart. "He'll smash the ladder!"
The boys started off after the animal but they were at considerable disadvantage. Bart had let go of the strap by which he was leading the donkey, and Fenn, who was also in front, had jumped to one side as he heard the beast break into a run. So the steed passed both of them. As for Frank and Ned, in the rear, they could not get ahead of the donkey because of the long ladder sticking out behind and swaying to and fro. By this time the animal was some distance in advance, running along one of the wider trails that led through the wood.
"We must catch him!" cried Frank. "He'll smash the ladder and we'll be in a fix then!"
The donkey seemed to be enjoying the sport. Faster and faster he ran, braying at the top of his voice. The ladder knocked against the tree trunks, sometimes throwing the animal to one side but this did not stop him.
"Cut ahead through the woods and try to catch him!" cried Ned to Bart, who was a little in advance.
Bart did so. He saw, through the trees, where the trail turned, and gliding between the bushes, he reached the path ahead of the donkey that was coming down it full speed. Bart braced his feet apart and stood ready to grab the beast.
But he reckoned without the ladder, which had become loose from the fastenings and was now resting evenly on the donkey's back, sticking straight out ahead like a long spear. It was this double-pointed lance that was aimed at Bart, and the donkey's head was fifteen feet back of it. Bart saw that he could not grasp the bridle.
Right at him came the donkey, braying as though in glee at the trick he had played. To avoid being impaled on the ladder ends Bart had to jump to one side. Standing in the bushes that were along the trail, he reached forward and tried to grasp the swaying halter rope that was fastened to the donkey's head. But the beast avoided him and ran on.
"Grab the end of the ladder and hold him!" shouted Bart to Ned, who was still in the rear.
Ned and Frank both tried. They managed to catch hold of the swaying end nearest them, but the donkey had more strength than they supposed. They were dragged along through the mud, and water, and then, as the animal turned suddenly, they were flung to one side.
"There he goes," exclaimed Ned ruefully as the animal disappeared around the bend. Bart and Fenn took after him.
"Come on; we've got to catch him!" cried Frank, and he and Ned set off after their companions.
All at once there arose a shouting from the boys in the lead. Then sounded a crash in the bushes. It was followed by a series of discordant brays from the donkey.
"Something has happened!" cried Frank. "Hurry up!"
Something had happened, sure enough. The donkey had caught himself. For, in trying to pass between two saplings, the ladder had slewed cross-ways and had brought the beast up with a round turn. Surprised and, perhaps somewhat indignant at the sudden stopping of his run, the donkey struggled on. The ladder slipped up the small trunks of the saplings and they began to bend.
"He'll break 'em off and escape again!" cried Ned. "Grab him Bart!"
Further and further over bent the two saplings. The ladder was sliding up them. Then the donkey slipped. He lost his foot-hold in the mud and the next instant a curious thing happened.
The saplings, being no longer strained forward by the animal, sprang upward. The ladder began to slip back. It went until it caught on some branches of either small tree and there it stayed. But the donkey was fairly lifted from his feet, for the ladder was still fastened to his back, and there he hung, his hoofs threshing about and his brays coming quickly in indignant protest at the treatment accorded him.
"That settles Mr. Donkey!" cried Bart, as, laughing loudly, he grabbed the halter rope. The other boys came up, filled with merriment over the plight of the beast that had thus trapped himself. They cut the branches that held the ladder and the donkey came back to earth. He did not try to run away, and seemed so much ashamed of what had happened that he stopped braying. Then, the ladder having been fastened in the proper position, the boys took up their journey. The rain was falling steadily.
