"Oh, Sammie!" cried Mab, running out to him, "What are you doing with those tomatoes?"

"Sammie goin' have a 'mato store an' sell 'em like you an' Hal. You want come my 'mato store?" he asked, looking up and smiling.

"No, I guess we have all the tomatoes we want," laughed Hal.

Sammie did not seem to worry about this. Maybe he thought some one else would buy his vegetables. He wheeled his cart up near his own front fence, on the grass and sat down beside it.

"'Mato store all ready," he said. "People come an' buy now."

But though several persons passed they did not ask Sammie how much his tomatoes were. They may have thought he was only playing, and that his tomatoes were not good ones, though they really were nice and fresh.

"We'd better go tell his father or mother," suggested Mab to her brother. "I don't believe they know he's here."

"Guess they don't," Hal agreed. "Come on; he might get hurt out there all alone."

Brother and sister started into the Porter yard. They did not see Sammie's mother, but his father was down in the back end of his lot, weeding an onion bed.

"Hello, children!" called Mr. Porter. "Did you come over to see how my garden is growing?"
