After a deliberate survey of the situation, Tim made a sudden spring to the side of his enemy, caught him under his chest, and turned him upon his back. This side attack was unexpected 106 and a perfect success, and the reptile had an active and prolonged struggle to regain his natural ition. Tim watched the struggle with intense interest, seeming to be happy in knowing that he held the key to the situation. From that time on, his guest during the daylight hours had no peace. Whenever Tim had an opportunity, he turned him over, and, when not engaged in that diversion, he was chasing him around the enclosure. About one month of such an existence brought the Saurian very near to his end. From a most healthy and vigorous “’gater” at the time he was caught he had become weak, weary and lank; so forlorn was his lamentable condition that he excited the sympathy of some human friend, who, during the night, opened the gate to the pen. The following morning the persecuted reptile was nowhere to be found. From that moment 107 Tim became his former self, watched anxiously at the gate for the coming of friends, and pleaded pertinaciously for the intoxicating beverage.
