Edmund Quincy Sewall Jr. writes in his journal:
At night we heard the frogs peeping and on Monday morning they were nowhere to be seen. They had probably crawled out of some hole in the cover of the barrel and made for the river as Mrs Thoreau affirmed that when she heard them in the night their voices seemed to recede in that direction. Mr Thoreau intended to have preserved them in spirits.
