As we were approaching Flinders' Bay on our return, a kangaroo was started some distance ahead of us; presently I observed an old dog, who was wont to "run cunning," suddenly stop close in front of me. The next moment the game, closely pursued, dropped in a bound, not six yards from where I stood, and before he could rise again, old "Ugly" had his prize by the throat. This proved to be a doe, and on examining her pouch a foetus was found in it, perfectly detached as usual, and about three inches and a half long. The generation, growth, and alimentation of the foetus of the kangaroo and other marsupial animals (ultra interine and detached from the parent, as it appears to be at all stages,) is a mystery in physiology which has yet to be unravelled. A "medico" who was of our party, did not neglect this opportunity for research. With a view to the investigation of the subject at leisure, he dropped the foetus into his glove for conveyance home. Outside the station of Flinders' Bay, we came upon a small limpid stream, brawling over a rocky bed, which seemed a suitable place to refresh the inner man with a sandwich, and a thimble full of Cognac. Segars were then lighted, and, shouldering our game, we resumed our route. The sun was low, when we descended the steep hill whence we opened a view of Eagle Hawk Neck and the Pacific, and after a long and toilsome ascent of the "Saddle," by a path which abounded more in loose sharp stones than any which it has been my misfortune to fall in with. However, refreshment was at hand, which we were quite in condition to appreciate, for we will back a day's kangarooing against any other sport, for giving a zest both to victuals and drink. Our host, C--, was famous for his kangaroo soup; this is made of the tail of the animal, and when well prepared may vie with any oxtail, if, indeed, it be not superior, having the advantage of a game flavor. The flesh of the kangaroo resembles in taste and appearance that of the hare, though drier and inferior in flavor when roasted. The only part thus cooked is the hind quarter, which should be boned, stuffed, and larded, and after all, the play is not worth the candle. Not so, "kangaroo steamer." To prepare this savory dish, portions of the hind quarter, after hanging for a week, should be cut into small cubical pieces; about a third portion of the fat of bacon should be similarly prepared, and these, together with salt, pepper, and some spice, must simmer gently in a stewpan for three or four hours. No water must enter into the composition, but a little mushroom ketchup added, which served, is an improvement.
