But snakes vary in temperament as we do, and some of these Zamenis serpents are as gentle and amiable as their cousin the Aesculap snake. My friend of this afternoon could not be induced to bite. Perhaps he was naturally mild, perhaps drowsy from his winter sleep or ignorant of the ways of the world; perhaps he had not yet shed his milk teeth. I am disposed to think that he forgot about biting because I made a favourable impression on him from the first. He crawled up my arm. It was pleasantly warm, but a little too dark; soon he emerged again and glanced around, relieved to discover that the world was still in its old place. He was not clever at learning tricks. I tried to make him stand on his head, but he refused to stiffen out. Snakes have not much sense of humour. Lizards are far more companionable. During two consecutive summers I had a close friendship with a wall-lizard who spent in my society certain of his leisure moments--which were not many, for he always had an astonishing number of other things on hand. He was a full-grown male, bejewelled with blue spots. A fierce fighter was Alfonso (such was his name), and conspicuous for a most impressive manner of stamping his front foot when impatient. Concerning his other virtues I know little, for I learnt no details of his private life save what I saw with my eyes, and they were not always worthy of imitation. He was a polygamist, or worse; obsessed, moreover, by a deplorable habit of biting off the tails of his own or other people's children. He went even further. For sometimes, without a word of warning, he would pounce upon some innocent youngster and carry him in his powerful jaws far away, over the wall, right out of my sight. What happened yonder I cannot guess. It was probably a little old-fashioned cannibalism. Though my meals in those days were all out of doors, his attendance at dinner-time was rather uncertain; I suspect he retired early in order to spend the night, like other polygamists, in prayer and fasting. At the hours of breakfast and luncheon--he knew them as well as I did--he was generally free, and then quite monopolized my company, climbing up my leg on to the table, eating out of my hand, sipping sugar-water out of his own private bowl and, in fact, doing everything I suggested. I did not suggest impossibilities. A friendship should never be strained to breaking-point. Had I cared to risk such a calamity, I might have taught him to play skittles.... For the rest, it is not very amusing to be either a lizard or a snake in Italy. Lizards are caught in nooses and then tied by one leg and made to run on the remaining three; or secured by a cord round the neck and swung about in the air--mighty good sport, this; or deprived of their tails and given to the baby or cat to play with; or dragged along at the end of a string, like a reluctant pig that is led to market. There are quite a number of ways of making lizards feel at home.
