in Thoreau’s Journal:

The weather has been very changeable for some weeks. First it is warm and thawing, sloshy weather; then the thermometer goes down to 19° below zero, and our shoes squeak on the snow; then, perhaps, it moderates and snows; then is mild and pleasant again and good sleighing; then we wake to find a drifted snow upon the last and a bleak, wintry prospect.
