Winter is a Study in Halftones

Winter is a study in halftones, and one must have an eye for them or go lonely.
— Donald Peattie, American botanist, naturalist, and author, An Almanac for Moderns, 1935

Notes:
November 16, 1964
Today is the anniversary of the death of the Harvard botanist, Naturalist, Washington Post nature columnist, and author, Donald Culross Peattie, who died at 66. During his lifetime, Donald Peattie was regarded as the most read nature writer in America.
Donald had an older brother named Roderick, who was a geographer and an essayist. Of his younger brother Donald, Roderick once wrote:
“My young brother Donald was very skinny and quite philosophical. He took every faith but theosophy. He had a wonderful memory and a love of beauty, which still marks his life. Doubtless, he was a genius, but I thought him a pest.”
