Howells on "in like a lion, out like a lamb"

Rhinelander Daily News:

Through the years, March’s trademark blustery winds and changeable weather have earned it several terms and expressions. There is an old saying we still hear that March “comes in like a lion and goes out like a lamb.”

The expression may have been inspired by poet William Dean Howells who wrote: “Tossing his mane of snows in wildest eddies ... Lion-like March cometh in hoarse.”

Howells on Garfield

From Minnesota Public Radio:
The war also forever changed Union general and future U.S. President James Garfield. "At the sight of these dead men whom other men had killed, something went out of him, the habit of a lifetime, that never came back again: The sense of the sacredness of life and the impossibility of destroying it," wrote 19th century author William Dean Howells of Garfield.
