"Can chipmunks chew through cement with their teeth?"
"I don't think so, no. Why?"
"Because I've been using the cement we keep under the Carriage Tree to build the dams."
"The Carriage Tree??"
"The one by the Bilco door. The one I sit in like a carriage."
"Oh! That tree. We keep cement under it?"
"Yes, and the round red rocks."
"Of course, with the round, red rocks. Our masonry supplies are very organized. Now, what's this about a dam?"
"Chipmunk dams. I build the chipmunk dams out of cement. It will keep them in their holes."
