In the reptile-house at these Gardens, the largest saurian bears the apt name of Little-'un. He is a youthful alligator, although, being rather more than 10 ft. 6 in. long, he has quite grown out of short frocks. Nothing infantile remains about his appearance, and he has in full development that curious cravat of fleshy folds and creases noticeable in no animals but alligators and 'bus-drivers, and among the latter species only in the stout and red-faced variety. Little-'un's name was not given him by way of a joke, but because, nine years ago, he was only a foot long--which _is_ little for an alligator. Little-'un has always been a good business alligator, however, and by strict industry and invincible perseverance in the pursuit of whatever might be eatable, has risen to an honoured and considerable eminence in the higher Zoo circles. To observe the open countenance of Little-'un bearing down on a piece of meat that ought properly to belong to some other alligator, is to get a sight of a truly original edition of "Smiles's Self-Help." Little-'un's one moral principle is--the greatest good of the greatest alligator. His business maxim is get something to eat; honestly, if there is no other way, but, anyhow, get it as large as possible, and as often as you can. He would, without the least bashfulness, proceed to eat his friends in the same tank if Tyrrell (the keeper, whom you know already) neglected the commissariat. Indeed, he once began on one fellow-lodger, with no other excuse than opportunity. Feeding was in progress, and, in the scramble and confusion, a smallish crocodile, lunging his nose in the direction of the desired morsel, without particularly noticing where that direction led, found himself up to the eyes in Little-'un's dental establishment. Little-'un's prudent habits rendered it unlikely that he would deliberately fling away anything that Providence had actually thrust into his mouth, even if it were his own grandfather: and only a vigorous application of Tyrrell's pole saved the crocodile from making a meal in a sense he didn't originally intend. Eighty-five degrees is the temperature prescribed for the water here, and every crocodile is a thermometer unto himself, soon showing signs, notwithstanding his thick hide, of any variation in the rate of his gentle stewing--Little-'un being as sensitive as any, in spite of his assiduous attention to business.
