One night Buddy Pigg's mamma came into his room, where he was sleeping soundly and dreaming he was playing a ball game with Bully and Bawly, the frogs, and Mrs. Pigg gently shook her little boy by the shoulder.

"Wake up, Buddy!" she called. "Wake up!"

"What's the matter, mother?" Buddy exclaimed, as he sat up in bed. "Is the house on fire?"

"No," she answered, "but your papa is very sick, and I want you to go for Dr. Possum." Then Buddy jumped up very quickly and began to dress, for he loved his papa very much, and would do anything in the world for him. When Buddy was ready to start he heard Dr. Pigg groaning very hard, and saying:

"Oh, dear, what a pain I have! Oh, dear! When will Dr. Possum come?"

"Buddy is going for him at once," Mrs. Pigg said. "He will soon be here. But have you no medicine that you can take?" For Dr. Pigg had once worked in a hospital, and generally had some medicine in the house, but this time he had none that would stop his pain. So Buddy had to get ready to go for the doctor, while Mrs. Pigg and Brighteyes made mustard plasters for Dr. Pigg.

Well, when Buddy was all dressed, he happened to look out of the window, and he saw how dark it was, for there was no moon that night, and the stars were all hidden behind clouds. But do you s'pose Buddy was going to stay home on that account? No, sir-ee! He was frightened, and I guess you'd have been, too, but he was brave, and he made up his mind he'd go for Dr. Possum.

So Buddy put on his hat and coat and went out of the front door and into the dark night, where, for all he knew, a bad fox might be waiting to grab him. But Buddy took a long stick, and he filled his pockets with stones, and he made up his mind he would throw them at the fox if he saw him.

The little guinea pig boy went on, and on, through the woods, toward Dr. Possum's home, and, after a while, he was not so frightened as he had been at first. Then, all of a sudden, as he was passing a big, black bush, he heard a funny noise. First he thought it was a wolf or a bear, and then he heard a voice say:

"Oh, come on down into the burrow, Waddy."

Then Buddy knew it was the two groundhog boys, Woody and Waddy, who had made the funny noises, but they didn't mean to scare him, and he wasn't at all frightened now. Woody and Waddy had heard Buddy coming along, and, a moment later, they saw him and asked where he was going.

"I'm going after Dr. Possum, because my papa is sick," said Buddy.

"Wait and we'll let you take our lantern," said Woody, and he hurried down into the burrow, and came back with a large bottle, filled with lightning bugs, which gave plenty of light. And it had a string on, to carry it by. As Buddy took it, very thankfully, Waddy said he hoped he would find the doctor at home.

Then Buddy started off again, but he hadn't gone much farther through the woods before he heard another noise. This noise was a real loud one, like some giant tramping up and down, and stamping his feet, and suddenly there came a great snort, and the earth seemed to shake, and a big, black thing jumped up in front of Buddy, scaring him frightfully.

He trembled so that the cork nearly came out of the bottle of lightning bugs, and, if it had, the fireflies would have been spilled all over the ground, worse than when you spill your ice cream cone—only it didn't happen, I'm glad to say, but almost. Then the black shape stood still, and a great voice called out:

"Where are you going with that lantern?"

"If you please, kind sir," answered the little boy guinea pig, "I'm going for Dr. Possum for my papa, who has a terrible pain. The groundhog boys lent me this lantern. But who are you, if you please, kind sir?"

"Why, I am Gup, the horse," was the answer. "So you are going for Dr. Possum, eh? He is a friend of mine. I'm sorry if I frightened you. Yes, I'm only Gup, the horse. You see, my name is Gup because there is a little boy at our house, and he can't talk very plainly, and he calls me 'Gup' when he wants to say 'get up,' you see. However, it doesn't much matter, and I don't mind.

"But, speaking of doctors, I know where Dr. Possum lives, and I'll take you right to his house in less than no time. Besides, you and your sister were so kind as to drive the cows home for the man who cut his foot, and as he is a friend of mine I want to return your kindness to him. Jump upon my back, Buddy."

"Oh, I'm afraid I'll fall," said Buddy, when he saw how high up Gup's back was from the ground.

"Nonsense!" exclaimed the horse. "I wouldn't let you fall for the world. Here, hold up your firefly lantern so you can see, climb upon that low stump, and then you can jump on my back. I'll stand still, and then I'll take you right to Dr. Possum's house."

So Buddy got up on Gup's back. It was the first time he had ever ridden a horse or been up so high, and, of course, for a while, he was frightened. But Gup told him just how to cling tightly to his big neck and how to hold the lantern so the lightning bugs would shine on the path, and then Gup started off.

Oh, how fast he went! Right through the woods, he galloped, and he never bumped into a tree or a bush even once. He went gently, too, so that Buddy would not fall off, and, my goodness sakes alive! in a short time the little guinea pig boy was at Dr. Possum's house. He knocked on the door, rat-a-tat-tat, and, luckily, the doctor was at home. He got right out of bed, took his satchel of medicines and was just going to get into his automobile to go to Dr. Pigg's house, when he found that his auto was broken. Either the spark was off the plug or the plug was off the spark, I forget which. Then Gup said:

"Get right up on my back, doctor. I can carry you and Buddy, too. It's no great weight, I assure you. Never mind the automobile. They are always making trouble."

So Dr. Possum, with his medicine box, climbed upon Gup's back, behind Buddy, and he helped hold the little guinea pig on during the ride home. Faster and faster went Gup through the dark woods his hoofs going "tat-a-tat-too," and he didn't bump into a tree or a bush, and he did not jar off Buddy or Dr. Possum, and pretty soon there they were safe at Dr. Pigg's house, and Dr. Possum gave Buddy's papa some medicine that soon made him better. Then Gup, the kind horsie, took Dr. Possum safely back through the dark woods as straight as a string.

In the morning Dr. Pigg was all well again, and he said Buddy was very brave to go off for a doctor in the night, and I think so, too.

Now, in case it doesn't thunder too hard and scare the chimney so that it falls off the roof, I'll tell you next about Buddy and Brighteyes tumbling down hill.
