The greatest elephant panic ever seen in this country was that created by Barnum’s Emperor, who suddenly developed all the characteristics of a rogue, while the circus was exhibiting in Troy, N.Y. The trouble commenced when an attempt was made to drive Emperor and Jumbo to the train. The former had decided objections to continuing the tour; and he suddenly bolted, and shuffled furiously up the street in the direction of the iron-foundery of Erastus Corning. The large door being open, the excited animal rushed in, and in a moment was trampling upon the red-hot coal and metal, uttering fierce shrieks. And now utterly enraged and mad, he rushed from the building into the crowded streets, trampling upon men, hurling others down an embankment with his trunk, breaking one man’s leg in his flight, throwing another twenty feet into the air, while a woman was taken from the stoop of a house and hurled into the street. In fact, the demon of rage seemed to possess the huge creature, that ran amuck until he had destroyed four thousand dollars’ worth of property. Another rogue elephant was Romeo, owned by the Forepaugh Company, who died in Chicago in 1872, having killed three men, and destroyed property valued at fifty thousand dollars. Almost equally vicious was Mr. Barnum’s Albert. This elephant killed its keeper at Keene, N.H.; and, after being loaded with chains, it was led out into the woods, followed by a large crowd, and a company of Keene riflemen. Its trainer, Arstinstall, marked the location of the heart upon the dark hide of the unsuspecting giant; and at the word, the great animal fell. These fits of frenzy are sometimes periodic, and the elephant is then said to be _must_, or mad. The paroxysms vary in different animals. Some are lethargic, or sleepy; while others go mad, and endeavor to wreak vengeance upon any thing within reach. In the chapter on the anatomy of the elephant, reference is made to a pore in the temple of the animal; and, when expert elephant-men see an oily liquid exuding from this orifice, they accept it as a warning that the period of _must_ is approaching; the elephant is immediately shackled, and keepers and strangers are warned to keep out of reach.
