Superintendent Hatfield of the Society for the Prevention of Cruelty to Children came aboard the "Only Son". He had heard reports of Jumbo's bad temper, and boarded the ship to be certain Jumbo was not a threat to the children of New York City. Barnum told him Jumbo was "perfectly lamb-like". Hatfield took a long look at Jumbo, then left the ship with the sense that Jumbo was indeed a gentle animal.
