An Almanac for Moderns contains a short essay for each day of the year that contemplates a unique but factual aspect of unbridled nature. According to a review in Nation, this collection of essays manages to "appeal to the ordinary lover of nature ...but the turn of Peattie's mind is poetic and speculative." The New York Times calls this book "a fine and subtle perception ...rising at times to an intense lyric beauty ...a book which the reader will deeply treasure, and to which he will repeatedly return."
