The store that Mrs. Goo-Cheese ran with her sister was located on the shore of the pond. It was made from logs that were flattened on the tops and bottoms with notches on the ends. This allowed the logs to fit together tightly to keep out the wind and the rain.

"We spread a large band of it around the outside of the fields. Being dry and uneatable, they usually turn around and go the other way. However, should they make it across, we have set out clay pots with some sugar water and yeast. The grubs are attracted to the yeast in the dishes where they crawl in to feed but they don't crawl out."
