But the big dog did not seem to mind in the least. He came when Russ called him, and he wagged his tail when the boys showed him the soap-box cart and the harness.
"Now we're going to have some fun when you give us a ride!" said Russ, patting Zip's shaggy head.
"Bow-wow!" barked the dog, as much as to say:
"That's right! We'll have fun!"
Daddy Bunker, as well as his wife and Grandma Bell, came out to see how the first trip would turn out. Tom put the harness on Zip. The dog only sniffed at it and wagged his tail. Perhaps he thought of the time when he had been harnessed this way by Bobbie.
"Oh, it's nice! I like it!" cried Mun Bun, when he saw the home-made dog-cart with the baby carriage wheels. "I want a ride now."
"So do I," added Margy, who never liked to be left, out of anything in which her smaller brother had a share.
"You little folks had better not get in until Russ and Laddie try it," said Mr. Bunker "And they had better keep on the soft grass when they start to drive Zip."
"Why should we stay on the grass?" asked Laddie.
"So if you fall out of the cart you won't get hurt," his father answered with a merry laugh.
