d it's salty, just like the ocean!"

"Sure enough it is!" agreed Brighteyes, taking a small mouthful to
taste. "I wonder what makes it?"

"And I wonder what makes the waves, and I wonder where Percival is?"
went on Buddy, and just then there came such a big wave that it almost
knocked him over, and he had to cling to the ropes. Then what should
happen, but that at the far end of the pond, up rose old dog Percival,
laughing as hard as he could laugh.

"I told you I would make waves!" he cried, and how do you s'pose he did
it?

Why, he had a big, empty box, and he would raise that up and down in the
water of the pond, as hard as he could, and this splashed, and made the
waves; and Percival had a bag of salt, to make the water salty. Now,
wasn't he the smart dog though?

Well, he went on, making more salty waves, and Buddy and Brighteyes
paddled around in them, and yelled and hollered, and held on to the
ropes, and ducked each other, and splashed and had as good a time as if
they had been at the seashore; and so did Percival, too, I guess. Then,
after a while they came out of the water and dried off, after thanking
Percival.

Now, if our bathtub doesn't freeze up so the canary bird can't go in
swimming I'll tell you presently about Buddy building a sand house.

STORY XXVIII

BUDDY BUILDS A SAND HOUSE

The little guinea pig children had so much fun bathing in the pond,
where Percival, the circus dog, made the salty waves for them, as I told
you about in the previous story, that they went in swimming as many
times as their mamma would let them.

Percival was only too glad to make the waves, and hold the bag of salt
in the pond, to make it salty, just like the ocean. Sometimes the old
dog would jounce a box up and down, to make the waves, and again, when
he wanted larger ones, he would use a barrel. Then the waves of the pond
would be over the heads of Buddy and Brighteyes, and they had to cling
to the ropes with all their might.

One day Buddy was sitting in the sand, on the banks of the pond, when,
all at once, he had an idea.

"I know what I'm going to do!" he exclaimed. "I'm gong to build a sand
house. I wish Brighteyes was here to help me," but his sister had gone
in the pen to help her mamma get dinner ready, for Mrs. Pigg expected
company that day; Mr. and Mrs. Bushytail were coming. So Buddy had to
start to build the house all alone. He piled a lot of sand in a heap,
together with stones, and s
