There was no affectation in this rhapsody--no girlish sentiment in the display; for nature called forth the gushing softness of her heart, and I quickly took advantage of this moment of philosophic romance.--Where is the lover who has not found the moon his silent yet most impassioned advocate, and who, when gazing on its mellow light, has not caught that saddened sympathy which brightens every dark spot in the horizon of the heart. "Yes," I replied, "it is the same cloud-wrapt sphere which has always looked down on the little drama of human folly, unmoved amid the desolations of death and the fall of empires, forever whispering love, and exalting the best affections of our nature. Marriages must be made in _heaven_--and this pale messenger, in expanding the heart, almost persuades me that it is commissioned to teach love and awaken affection." Ere she could reply, I placed a leaf of evergreen in her hand, and uttered enough of love to call a burning blush to her cheek. I lingered for a few moments at the door, and on leaving the scene, I turned around to gaze on the being who was thus insensibly falling into the toils of my duplicity. I saw her place in her bosom the treacherous emblem which I had given her; and as the silvery light of the moon trembled over her marbled brow and placid countenance, I almost believed that its rays had claimed that spot, as the only tranquil home in the wide world on which they might kiss themselves into slumber.

It is of great extent, and affords the visiter as much information as amusement. It was founded by Jean de Brosses, the physician of Louis XIII, and much improved by the exertions of Buffon the naturalist. It contains various enclosures, some of which are appropriated to botany, and display every plant, flower and shrub, native and foreign, that can be made to grow there. Each is labelled, and bears its botanical name; and there are spacious hot-houses for such as require shelter and extreme care. We remarked here some fine specimens of the bread tree and sugar cane. Other enclosures are filled with all sorts of culinary vegetables. There are besides, nurseries of fruit trees and samples of different kinds of fences, hedges and ditches, and of various soils and manures. The enclosures are separated by wide gravel walks,
