Like W.H. Hudson (with whom Jefferies is usually, and with reason, grouped), Richard Jefferies was arguably the greatest writer on the natural world that the British Isles ever produced. While he was a peerless naturalist in the formal scientific sense, one can only understand Jefferies's work if one counts him as a poet and, far and away above all else, a pantheistic nature mystic. For Jefferies, the experience of communion with Nature (with a capital N) was a matter of religion---a religion that has nothing to do with God or gods, creeds, churches and the rest of it (Jefferies was an unbeliever by any tolerably orthodox standards), but the primal religion of the individual human being confronting the Cosmos as revealed through the natural world. 'The Life of the Fields,' for instance, is a collection of essays that put this world under the microscope of the human soul. It's such a pity that space forbids even a brief taste of Jefferies' rapturous, Nature-intoxicated style, although perhaps titles such as 'The Pageant of Summer' (arguably his finest piece in this collection), 'Meadow Thoughts,' 'Sea, Sky and Down' and 'January in the Sussex Woods' give a foretaste of what Jefferies was about in all his writings. if you have ever taken a walk in the open countryside and felt the innate beauty and mystery inherent therein, Wordsworth's "presence that disturbs me with a sense of joy, whose light is the light of setting suns" (as this reviewer certainly has), then Jefferies is the man who you will recognise as having missed so far in your life. These days writers such as Jefferies and Hudson are not only unread but practically entirely unknown except to a few (almost a select few, I nearly said) who have been fortunate enough to stumble across him and open their minds to such wonders, and I have to say that Amazon have to be congratulated for keeping these largely undiscovered treasures alive for future generations to discover.
