The other end of the avenue, where there was also an iron gate, admitted to a large private park that seemed to belong to nobody, and of which we were free--a very wilderness of delight, a heaven, a terror of tangled thickets and not too dangerous chalk cliffs, disused old quarries and dark caverns, prairies of lush grass, sedgy pools, turnip fields, forests of pine, groves and avenues of horse-chestnut, dank valleys of walnut-trees and hawthorn, which summer made dark at noon; bare, wind-swept mountainous regions whence one could reconnoitre afar; all sorts of wild and fearsome places for savages and wild beasts to hide and small boys to roam quite safely in quest of perilous adventure. All this vast enclosure (full of strange singing, humming, whistling, buzzing, twittering, cooing, booming, croaking, flying, creeping, crawling, jumping, climbing, burrowing, splashing, diving things) had been neglected for ages--an Eden where one might gather and eat of the fruit of the tree of knowledge without fear, and learn lovingly the ways of life without losing one's innocence; a forest that had remade for itself a new virginity, and become primeval once more; where beautiful Nature had reasserted her own sweet will, and massed and tangled everything together as though a Beauty had been sleeping there undisturbed for close on a hundred years, and was only waiting for the charming Prince--or, as it turned out a few years later, alas! the speculative builder and the railway engineer--those princes of our day. My fond remembrance would tell me that this region was almost boundless, well as I remember its boundaries. My knowledge of physical geography, as applied to this particular suburb of Paris, bids me assign more modest limits to this earthly paradise, which again was separated by an easily surmounted fence from Louis Philippe's Bois de Boulogne; and to this I cannot find it in my heart to assign any limits whatever, except the pretty old town from which it takes its name, and whose principal street leads to that magical combination of river, bridge, palace, gardens, mountain, and forest, St. Cloud. What more could be wanted for a small boy fresh (if such be freshness) from the very heart of Bloomsbury? That not a single drop should be lacking to the full cup of that small boy's felicity, there was a pond on the way from Passy to St. Cloud--a memorable pond, called "La Mare d'Auteuil," the sole aquatic treasure that Louis Philippe's Bois de Boulogne could boast. For in those ingenuous days there existed no artificial lake fed by an artificial stream, no pre-Catelan, no Jardin d'Acclimatation. The wood was just a wood, and nothing more--a dense, wild wood, that covered many hundreds of acres, and sheltered many thousands of wild live things. Though mysteriously deep in the middle, this famous pond (which may have been centuries old, and still exists) was not large; you might almost fling a stone across it anywhere. [Illustration]
