William Cowper as a poet of Nature, is marked first by the narrowness of the limits within which he writes. Mountains[467] are merely mentioned. Night is nowhere described. Moonlight plays no part in his poetry.[468] The stars are occasionally spoken of, but only in a conventional manner as “shining hosts,” “fair ministers of light,” or “beamy fires.” Of wild scenery there is none. The nearest approach to it is in two brief descriptions of rocky bluffs on the seashore.[469] His references to the ocean are brief and not of much importance; nor are there any storms except in a few lines about “a driving, dashing rain” with thunder and lightning used as an “apt similitude.”[470] The one winter storm is merely a gentle fall of snow that comes after the evening curtains are tight drawn.[471] The similitudes, though often carefully elaborated, show little if any new use of Nature, and they are drawn from a small number of natural facts.[472] The explanation of this narrowness of limit is twofold. Cowper described only what he had seen,[473] and he had seen no country but his own, and only a very small and comparatively uninteresting portion of that. The Downs about Bath, where he seems to have been for a short time when he was about eighteen, was the nearest approach to wild scenery that he had ever known. During the seventeen years before the writing of “The Task” (1785) he had seldom left Olney, and never for a fortnight together.[474] His knowledge was further limited by his continued ill-health. He was ignorant of certain phases of the out-door world simply because his physical infirmities kept him in the house. This explanation of the narrow range of the Nature in Cowper’s poetry is not entirely satisfactory, for when we come to his letters we find suggestions of a wider experience and sympathy than the poems would indicate. In a letter to Joseph Hill he wrote: I was always an admirer of thunderstorms, even before I knew whose voice I heard in them; but especially an admirer of thunder rolling over the great waters. There is something singularly majestic in the sound of it at sea, where the eye and the ear have uninterrupted opportunity of observation, and the concavity above, being made spacious, reflects it with more advantage.... We have indeed been regaled with some of those bursts of ethereal music.... But when the thunder preaches, an horizon bounded by the ocean is the only sounding board. To the Rev. William Unwin, September 26, 1781, he wrote:
