"Couldn't Sammie and Susie Littletail come, too?" asked Buddy.
"No, they have gone to Belmar, at the seashore, for the summer," answered Uncle Wiggily. "But now we must hurry off to the mountains."
So they hurried off, and in a little while, oh, not so very long, Dr. Pigg and his family, and Uncle Wiggily arrived at a nice pen, right on the side of a mountain, at the foot of which was a large lake.
There were so many things to see that Buddy and Brighteyes did not know at which to look first, and they ran all about, now to one place, and now to another. Then, when they had had their supper, Uncle Wiggily said:
"Come now, we will take a walk. I think I know where there is a cave, and we will see if a giant lives in it."
"A real giant?" asked Buddy.
"No, only a make-believe one," answered Uncle Wiggily, with a laugh. So he and the two guinea pig children started off up the side of the mountain toward the cave. All around them were other mountains, and it was a lovely place, with the red sun sinking down behind the hills, just like it does in poetry.
"Ha, here we are at the cave!" exclaimed Uncle Wiggily, at length, as they came to a big hole in the side of the mountain. "Now, Buddy and Brighteyes, be very careful. Keep close to me, and don't go in very far, or you may get lost."
