Thoreau writes in his journal:
Heard Professor Blasius lecture on the tornado this evening. He said that nine vessels were wrecked daily in the world on an average; that Professor Dove of Berlin was the best meteorologist in his opinion, but had not studied the effects of wind in the fields so much as some here . . .
The audience are never tired of hearing how far the wind carried some man, woman, or child, or family Bible, but they are immediately tired if you undertake to give them a scientific account of it.
Concord, Mass. Lidian Jackson Emerson writes to her husband Ralph Waldo on 6 February:
[Blasius lectured on “Tornado” for the Concord Lyceum [?] on 4 February]
