From Colonel Lyon’s Letters.
Feb. 28, 1863.—The water is very high, and rising about one foot in 24 hours. It is at least 30 feet above its ordinary height last fall. We have built a bridge of logs over the ravine (see map), as the water rose, and I think it must be 15 feet high and 20 to 25 rods long. The logs are laid up crib fashion, with plank on top. A rise of four feet more will cover the ridge nearest the river and drive our troops out of the fort. A rise of five or six feet will let steamers run up to our camp. They could come up now through the ravine were it not for the trees.
The weather is delightful, just like your most pleasant May. This is a great country for frogs. They keep up a terrible clatter every night.
