We went to Goose pond where we heard a tremendous chirping of frogs. It has been disputed whether the noise was caused by frogs so we were very curious to know what it was. Mr Thoreau however caught 3 very small frogs two of them in the very act of chirping. While bringing them home one of them chirped in his hat. He carried them to Mr Emerson in a tumbler of water. They chirped there also.

  On Sunday morning I believe he put them into a barrel with some rainwater in it. he threw in some sticks for them to rest on. They some times rested on these sticks. They sometimes crawled up the side of the barrel. I saw one of them chirping he had swelled out the loose skin of his chest like a little bladder.
