Silenziosa luna!"
this man should have lain upon some mountain-top, among the scent of rosemary and of fragrant myrtle, rather than in such a reeking dirty village as Fuorigrotta.
But I forget!—the compelling interest of this day's journey is not literary. A short walk from Fuorigrotta brings me to a point where the road turns slightly upward to the right, leading me to the brow of a hill, over which I look into a wooded hollow—none other than the Lago d'Agnano, once a crater, then a volcanic lake. Oddly enough, it is not mentioned as a lake by any ancient writer. Pliny describes the Grotta del Cane, which we are about to visit, but says not a word of any lake. This fact, with some others, suggests that the water appeared in this old crater only in the Middle Ages; though it really does not matter much, for it is gone now. The bottom has been reft from the fishes and converted into fertile soil. The sloping heights which wall the basin have a waste and somewhat blasted aspect; but I was not granted time to muse on these appearances before a smiling but determined brigand, belonging to the class of guides, sauntered up with a small cur running at his heels and made me aware that I had reached the entrance of the Dog Grotto.
I might have known it; for, in fact, through many centuries up to that recent year when it pleased the Italians to drain the lake, the life of the small dogs dwelling in this neighbourhood has been composed of progresses from grotto to lake and back again, first held up by the heels to be stifled by the poisonous gas, then soused head over ears in the lake with instructions to recover quickly because another carriage was coming down the hill. Thus lake and grotto were twin branches of one establishment, now dissolved. Perhaps the lake was the more important of the two, since it is easier to stifle a dog or man than to revive him; and on many occasions there would have been melancholy accidents had not the cooling waters been at hand. For instance it is related by M. de Villamont, who came this way when the seventeenth century was very young indeed, that M. de Tournon, a few years before, desiring to carry off a bit of the roof of the grotto, was unhappily overcome by the fumes as he stood chipping off the piece he fancied, and tumbled on the floor, as likely to perish as could be wished by the bitterest foe of those who spoil ancient monuments. His friends promptly dragged him out and tossed him into the lake. It is true the cure found so successful with dogs proved somewhat less so with M. de Tournon, for he died a few days later. Yet had the lake been dry, as it is to-day, he would have died in the cave, which would surely have been worse.
The little dog—he was hardly better than a puppy—looked at me and wagged his tail hopefully. I understood him perfectly. He had detected my nationality; and I resolved to be no less humane than a countrywoman of my own who visited this grotto no great while ago, and who, when asked by the brigand whether he should put the dog in, answered hastily, "Certainly not." "Ah!" said the guide, "you are Englees! If you had been American you would have said, 'Why, certainly.'" I made the same condition. The fellow shrugged his shoulders. He did not care, he knew another way of extorting as many francs from me; and accordingly we all went gaily down the hill, preceded by the happy cur, running on with tail erect, till we reached a gate in the wall through which we passed to the Grotta del Cane.
A low entrance, hardly more than a man's height, a long tubular passage of uniform dimensions sloping backwards into the bowels of the hill—such is all one sees on approaching the Dog Grotto. A misty exhalation rises from the floor and maintains its level while the ground slopes downwards. Thus, if a man entered, the whitish vapour would cling at first about his feet. A few steps further would bring it to his knees, then waist high, and in a little more it would rise about his mouth and nostrils and become a shroud indeed; for the gas is carbonic acid, and destroys all human life. King Charles the Eighth of France, who flashed across the sky of Naples as a conqueror, came here in the short space of time before he left it as a fugitive, bringing with him a donkey, on which he tried the effects of the gas. I do not know why he selected that animal; but the poor brute died. So did two slaves, whom Don Pietro di Toledo, one of the early Spanish viceroys, used to decide the question whether any of the virtue had gone out of the gas. That question is settled more humanely now. The guide takes a torch, kindles it to a bright flame, and plunges it into the vapour. It goes out instantly; and when the act has been repeated some half-dozen times the gas, impregnated with smoke, assumes the appearance of a silver sea, flowing in rippling waves against the black walls of the cavern.
With all its curiosity the Dog Grotto is a deadly little hole, in which the world takes much less interest nowadays than it does in many other objects in the neighbourhood of the Siren city, going indeed by preference to see those which are beautiful, whereas not many generations ago it rushed off hastily to see first those which are odd. For that reason many visitors to Naples neglect this region of the Phlegræan fields and are content to wait the natural occasion for visiting the mouth of Styx, over which all created beings must be ferried before they reach the nether world. It is a pity; for, judged from the point of beauty solely, there is enough in the shore of the Bay of Baiæ to content most men. The road mounts upon the ridge which parts the slope of Lago d' Agnano from the sea. One looks down from the spine over a broken land of vineyards to a curved bay, an almost perfect semicircle, bounded on the left by the height of Posilipo, with the high crag of the Island of Nisida, and on the right by Capo Miseno, the point which took its name from the old Trojan trumpeter who made the long perilous voyage with Æneas, but perished as he reached the promised land where at last the wanderers were to find rest. The headland, which, like every other eminence in sight, is purely volcanic, is a lofty mass of tufa, united with the land by a lower tongue, like a mere causeway; and on the nearer side stands the Castle of Baiæ, with the insignificant townlet which bears on its small shoulders the burden of so great a name. Midway in the bay the ancient town of Pozzuoli nestles by the water's edge, deserted this long while by all the trade which brought it into touch with Alexandria and many another city further east, filling its harbour with strange ships, crowding its quays with swarthy sailors, and with silks and spices of the Orient. All that old consequence has gone now like a dream, and no one visits the cluster of old brown houses for any other reason than to see that which is still left of its ancient greatness. But before going down the hill, I turn aside towards a gateway on my right, which admits me to a place of strange and curious interest. It is the Solfatara, and is nothing more or less than the crater of a half-extinct volcano, which, having lain torpid for full seven centuries, is now a striking proof of the fertility of volcanic soil, and the speed with which Nature will haste to spread her lushest vegetation even over a thin crust which covers seething fires. It was so once with the crater of Vesuvius, which, after five centuries of rest, filled itself with oaks and beeches, and covered its slopes with fresh grass up to the very summit.
Indeed, on entering the inclosure of the Solfatara, one receives the impression of treading the winding alleys of a well-kept and lovely park. The path runs through a pretty wood. The trees are scarcely more important than a coppice; but under their green shade there grows a wealth of flowers of every colour, glowing in the soft sunshine which filters through the boughs. There is the white gum-cistus, which is so strangely like the white wild rose of English hedges, and the branching asphodel, with myriads of those exquisite anemones, lilac and purple, which make the woods of Italy in springtime a perpetual joy to us who come from colder climates; and among these, a profusion of smaller blossoms trailing on the ground, crimson, white and orange, making such a mass of colour as the most cunning gardener would seek vainly to produce. One lingers and delays among these woods, doubting whether any sight which may be shown one further on can compensate for the loss of the cool glades.
But already over the green coppice bare grey hillsides have come in sight. They are the walls of the old crater, and here and there a puff of white smoke curling out of a cleft reminds me that the flowers are only here on sufferance, and that the whole hollow is in fact but waiting the moment when its hidden fires will break forth again, and vomit destruction over all the country. A few yards further on the coppice falls away. The flowers persist in carpeting the ground; but in a little way they too cease, the soil grows grey and blasted. Full in front there rises a strange scene of desolation. The wall of the crater is precipitous and black. At its base there are openings and piles of discoloured earth which suggest the débris of some factory of chemicals, an impression which is driven home by the yellow stains of sulphur which lie in every direction on the grey
