“Wow, this sounds hard,” Emma said. “What does a black walnut leaf look like?”
But her father said, “Wait, maybe not. Look, there are sign posts by some of the trees. Let’s see what they say.”
They walked over to the first one. The small square sign sat atop a wooden post. The sign told the name of the tree and had a picture of the tree’s leaf and seed.
Emma read the sign aloud, “Hemlock. This isn’t a black walnut tree.”
“That’s ok,” replied Mr. O’Brien, “let’s keep looking.”
The next sign they came to said “Black Walnut” “This is it!” exclaimed Emma. “Good work,” said Emma’s father. “Now we need to look for the clue.”
