" The whole force of Lake Erie, drawn into the strickness of a large river, formed a mass of water which falls 300 feet perpendicular; we went through under the water to the other side quite dry. And I assure you, tho' I have heard the thunder imitated in the field, that it was no way comparable to the noise that this immense body makes in it's fall. You would not hear the report of a cannon, was it fired at the bottom. I was absolutely deaf for 24 hours after I left."
