He stepped into the boat, anticipating an hour's enjoyment. A short while after this, Mrs. Hardcastle, accompanied by Mrs. Dundyke, came on to Rousseau's Island. Mr. Dundyke was not so far off then, but that his wife recognised him. Mr. Hardcastle was the next to come up. "What are you looking at? Why, who's that in a boat there? Surely not Dundyke! Give me the glass." "Yes, it is," said Mrs. Dundyke. "Where in the name of wonder is he off to, this melting day? To drown himself?" The ladies laughed. "Ah! I see; he can't stand it. The men are bearing off to the side--going to land him there. They had better put back." Mrs. Dundyke sat down underneath the poplar trees, spreading a large umbrella over her head, and took out her work. Mrs. Hardcastle was never seen to do any work, but she seated herself under the shade of the umbrella; and the gentleman, leaving them to themselves, walked back again over the suspension bridge. CHAPTER IV. A MYSTERY. Which of the three wore the deepest tint, the darkest blue--the skies, the hills, or the lake? Each was of a different shade, but all were blue and beautiful; and on all lay the aspect of complete repose. The two ladies, in that little garden near the Hôtel des Bergues, Rousseau's Island, as it is called, and which you who have sojourned in Geneva remember well, looking out over the lake at the solitary boat bearing away towards the right, noticed that no other object broke the prospect's stillness. It was scarcely a day for a row on Geneva's lake. Not a breath of air arose to counteract the vivid heat of the August sun; hot and shadeless he poured forth his overpowering blaze; and, lovely as the lake is, favoured by nature and renowned in poetry, it was more lovely that day to look at than to glide upon.
