L---- left me yesterday,--sooner than he had intended. I am extremely sorry for it; for so agreeable and friendly a companion doubles every pleasure. I afterwards drove with an acquaintance of the Guards, to St. Leonard's Hill, belonging to Field-marshal Lord H----, to whom E---- had given me a letter. The weather, which had been overcast, and from time to time rainy, was splendid; scarcely a cloud in the sky. On no more beautiful day could I see a more beautiful place than St. Leonard's Hill. These giant trees; this fresh wood, full of variety; these enchanting views, both far and near; this delightful house, with the most lovely of all flower-gardens; this luxuriant vegetation, and this delicious retirement, from which, as from behind a curtain, you look out upon a world of diversified beauty lying in the valley beneath,--form a whole which has not its equal in England. The possessors are a very agreeable old couple, unfortunately without children to whom to transmit this paradise. The old lord seemed much pleased at my enthusiasm for the beauties of the place, and invited me to spend the following day, which I accepted with great pleasure. To-day I was engaged to dine with my friend Captain B---- at the Guards' mess at Windsor, where I passed the evening, from six o'clock till midnight. At an early hour in the morning I was summoned by Lord H----, who is Ranger of Windsor Park, and wished to show it me before the King made his appearance. As soon as he rides out, the private part of the ground is hermetically sealed to every one, without exception, who does not belong to his own invited company. I was rather late; the kind-hearted old lord scolded me a little, and made me instantly get into a landau drawn by four noble horses, in which we rolled rapidly through the high beech woods.
