But we have not yet explored the north side of the grounds, where the huge pachydermatous animals are lodged. The difficulty caused by the carriage-drive running between the two gardens has been vanquished by means of the tunnel, the ascent from which on the opposite side, flanked as it is with graceful ferns, is one of the most charming portions of the grounds on a hot summer's day. If after passing through the subterranean passage we turn to the right, we come immediately upon the reptile-house. Unless the visitor selects his time, he will generally find little to amuse him here. The great snakes have either retired from public life under their blankets, or lie coiled upon the branches of trees in their dens. The reptiles are offered food once a week, but will not always feed at this interval. One huge python fasted the almost incredible time of twenty-two months, having probably prepared himself for his abstinence by a splendid gorge. After a fast of seven days, however, the majority of the serpents regain their appetites. Three o'clock is the feeding-time, and the reptiles which are on the look-out seem to know full well the errand of the man who enters with the basket, against the side of which they hear the fluttering wings of the feathered victims and the short stamp of the doomed rabbits. The keeper opens the door at the back of the den of the voluminous serpents on our right--for of these there is no fear,--takes off their blanket, and drops in upon the clattering pebbles a scampering rabbit, who hops from side to side, curious to inspect his new habitation; presently, satisfied, he sits on his haunches and leisurely begins to wash his face. Silently the rock-snake glides over the stones, uncurling his huge folds, which, like a cable, seem to move as though by some agency from without, looks for an instant upon his unconscious victim, and the next has seized him with his cruel jaws. His constricting folds are twisted as swiftly as a whip-lash round his shrieking prey, and for ten minutes the serpent lies still, maintaining his mortal knot until his prey is dead, when, seizing him by the ears, he draws him through his vice-like grip, crushing every bone, and elongating the body preparatory to devouring it. The boa and the rock-snake always swallow their prey head foremost. How is that fine neck and delicate head to make room for that bulky rabbit? thinks the spectator. Presently he sees the jaws gape, and slowly the reptile _draws himself over_, rather than swallows, his prey, as you draw a stocking upon your leg. The huge lump descends lower and lower beneath the speckled scales, which seem to stare with distension, and the monster coils himself up once more to digest his meal in quiet. Rabbits and pigeons form the food of the pythons in these gardens. While the smaller birds are preyed upon in the reptile-house, their big brothers, the storks in the paddock, are reciprocating the law of nature by eating snakes.
