In large gardens where ample space permits, and even in those of narrow limits, nothing is more desirable than that there should be some places, or one at least, of quiet greenery alone, without any flowers whatever. In no other way can the brilliancy of flowers be so keenly enjoyed as by pacing for a time in some cool green alley and then passing on to the flowery places. It is partly the unconscious working out of an optical law, the explanation of which in every-day language is that the eye, being, as it were, saturated with the green colour, is the more ready to receive the others, especially the reds.   

Even in quite a small garden it is often possible to arrange something of the sort. In the case of a place that has just one double flower-border and a seat or arbour at the end, it would be easy to do by stopping the borders some ten feet away from the seat with hedges of yew or hornbeam, and putting other seats to right and left; the whole space being turfed.   

The seat was put at the end in order to give the whole view of the border while resting; but, after walking leisurely along the flowers and surveying their effect from all points, a few minutes' rest on one of the screened side seats would give repose to the eye and brain as well as to the whole body, and afford a much better preparation for a further enjoyment of the flowers.   

It was probably some such consideration that influenced the designers of the many old gardens of England, where yew, the grand walling tree, was so freely used. The first and obvious use was as a protection from wind and a screen for privacy, then as a beautiful background, and lastly perhaps for resting and refreshing the eye, and giving it renewed appetite between its feasts of brilliant colouring and complex design. These green yew-bordered alleys occur without end in the old gardens. They were not always bowling-greens, though now often so called, but rather secluded ambulatories; places either for solitary meditation and refreshment of mind, or where friends would meet in pleasant converse, or statesmen hold their discourse on weightier matters. Such a place of cool green retreat is this straight alley of ancient yews.   

Almost better it might have been if the path were green and grassy too — Nature herself seems to have thought so, for she greens the gravel with mossy growths. Perhaps this mossiness afflicts the gardener's heart — let him take comfort in knowing how much it consoles the artist. Though a garden is for the most part the better for being kept trim, there are exceptional cases such as this, where to a certain degree it is well to let natural influences have their way. It is a matter respecting which it is  difficult to lay down a law; it is just one for nice judgment. Had the path been freshly scratched up and rolled, and the verges trimmed to a perfectly true line, it would not have commended itself to the artist as a subject for a picture, but, as it is, it is just right. The mossy path is in true relation for colour to the trees and grassy edges, and the degree of infraction of the canons of orderliness stops short of an appearance of actual neglect.   

Among the interesting features of the grounds at Rockingham is a rose-garden, circular in form, bounded and protected by a yew hedge. Four archways at equal points, cut in the hedge, with straight paths, lead to a concentric path within which is a large round bed, with poles and swinging garlands of free-growing Roses. The outer quarters have smaller beds, some concentric, some parallel with the straight paths. The space is large enough to give ample light and air to the Roses, while the yew hedge affords that comforting shelter from boisterous winds that all good Roses love.   

Close to the house a flight of steps leads to a flower garden on the higher level. A sundial on steps stands in the midmost space, with beds and clumps of bright flowers around. There is other good gardening at Rockingham, and a curious "mount"; not of the usual circular shape, but in straight terraces. But it is these grand old hedges of yew that seem to cling most closely to the fabric and sentiment of the ancient building — half house, half castle, whose windows have looked upon them for hundreds of years, and whose inmates have ever paced within their venerable shade.
