The nut-trees have grown into such thick clumps that now there must be a vigorous thinning. Each stool has from eight to twelve main stems, the largest of them nearly two inches thick. Some shoot almost upright, but two or three in each stool spread outward, with quite a different habit of growth, branching about in an angular fashion. These are the oldest and thickest. There are also a number of straight suckers one and two years old. Now when I look at some fine old nut alley, with the tops arching and meeting overhead, as I hope mine will do in a few years, I see that the trees have only a few stems, usually from three to five at the most, and I judge that now is the time to thin mine to about the right number, so that the strength and growing power may be thrown into these, and not allowed to dilute and waste itself in growing extra faggoting. The first to be cut away are the old crooked stems. They grow nearly horizontally and are all elbows, and often so tightly locked into the straighter rods that they have to be chopped to pieces before they can be pulled out. When these are gone it is easier to get at the other stems, though they are often so close together at the base that it is difficult to chop or saw them out without hurting the bark of the ones to be left. All the young suckers are cut away. They are of straight, clean growth, and we prize them as the best possible sticks for Chrysanthemums and potted Lilies.
After this bold thinning, instead of dense thickety bushes we have a few strong, well-branched rods to each stool. At first the nut-walk looks wofully naked, and for the time its pictorial value is certainly lessened; but it has to be done, and when summer side-twigs have grown and leafed, it will be fairly well clothed, and meanwhile the Hellebores will be the better for the thinner shade.
The nut-catkins are already an inch long, but are tightly closed, and there is no sign as yet of the bright crimson little sea-anemones that will appear next month and will duly grow into nut-bearing twigs. Round the edges of the base of the stools are here and there little branching suckers. These are the ones to look out for, to pull off and grow into young trees. A firm grasp and a sharp tug brings them up with a fine supply of good fibrous root. After two years in the nursery they are just right to plant out.
The trees in the nut-walk were grown in this way fourteen years ago, from small suckers pulled off plants that came originally from the interesting cob-nut nursery at Calcot, near Reading.
I shall never forget a visit to that nursery some six-and-twenty years ago. It was walled all round, and a deep-sounding bell had to be rung many times before any one came to open the gate; but at last it was opened by a fine, strongly-built, sunburnt woman of the type of the good working farmer's wife, that I remember as a child. She was the forewoman, who worked the nursery with surprisingly few hands—only three men, if I remember rightly—but she looked as if she could do the work of "all two men" herself. One of the specialties of the place was a fine breed of mastiffs; another was an old Black Hamburg vine, that rambled and clambered in and out of some very old greenhouses, and was wonderfully productive. There were alleys of nuts in all directions, and large spreading patches of palest yellow Daffodils—the double Narcissus cernuus, now so scarce and difficult to grow. Had I then known how precious a thing was there in fair abundance, I should not have been contented with the modest dozen that I asked for. It was a most pleasant garden to wander in, especially with the old Mr. Webb who presently appeared. He was dressed in black clothes of an old-looking cut—a Quaker, I believe. Never shall I forget an apple-tart he invited me to try as a proof of the merit of the "Wellington" apple. It was not only good, but beautiful; the cooked apple looking rosy and transparent, and most inviting. He told me he was an ardent preacher of total abstinence, and took me to a grassy, shady place among the nuts, where there was an upright stone slab, like a tombstone, with the inscription:
TO ALCOHOL.
He had dug a grave, and poured into it a quantity of wine and beer and spirits, and placed the stone as a memorial of his abhorrence of drink. The whole thing remains in my mind like a picture—the shady groves of old nuts, in tenderest early leaf, the pale Daffodils, the mighty chained mastiffs with bloodshot eyes and murderous fangs, the brawny, wholesome forewoman, and the trim old gentleman in black. It was the only nursery I ever saw where one would expect to see fairies on a summer's night.
I never tire of admiring and praising Iris stylosa, which has proved itself such a good plant for English gardens; at any rate, for those in our southern counties. Lovely in form and colour, sweetly-scented and with admirable foliage, it has in addition to these merits the unusual one of a blooming season of six months' duration. The first flowers come with the earliest days of November, and its season ends with a rush of bloom in the first half of April. Then is the time to take up old tufts and part them, and plant afresh; the old roots will have dried up into brown wires, and the new will be pushing. It thrives in rather poor soil, and seems to bloom all the better for having its root-run invaded by some stronger plant. When I first planted a quantity I had brought from its native place, I made the mistake of putting it in a well-prepared border. At first I was delighted to see how well it flourished, but as it gave me only thick masses of leaves a yard long, and no flowers, it was clear that it wanted to be less well fed. After changing it to poor soil, at the foot of a sunny wall close to a strong clump of Alströmeria, I was rewarded with a good crop of flowers; and the more the Alströmeria grew into it on one side and Plumbago Larpenti on the other, the more freely the brave little Iris flowered. The flower has no true stem; what serves as a stem, sometimes a foot long, is the elongated style, so that the seed-pod has to be looked for deep down at the base of the tufts of leaves, and almost under ground. The specific name, stylosa, is so clearly descriptive, that one regrets that the longer, and certainly uglier, unguicularis should be preferred by botanists.
What a delight it was to see it for the first time in its home in the hilly wastes, a mile or two inland from the town of Algiers! Another lovely blue Iris was there too, I. alata or scorpioides, growing under exactly the same conditions; but this is a plant unwilling to be acclimatised in England. What a paradise it was for flower-rambles, among the giant Fennels and the tiny orange Marigolds, and the immense bulbs of Scilla maritima standing almost out of the ground, and the many lovely Bee-orchises and the fairy-like Narcissus serotinus, and the groves of Prickly Pear wreathed and festooned with the graceful tufts of bell-shaped flower and polished leaves of Clematis cirrhosa!
It was in the days when there were only a few English residents, but among them was the Rev. Edwyn Arkwright, who by his happy discovery of a white-flowered Iris stylosa, the only one that has been found wild, has enriched our gardens with a most lovely variety of this excellent plant. I am glad to be able to quote his own words:—
