REPORT OF THE SECRETARY. 85 



order to preA^ent feeding by visitors a glass screen was erected be- 

 tween this cage and the public space. Pure air is provided by a duct 

 leading from the outside of the building suitably warmed by a heat- 

 ing coil. He has made himself entirely at home there, appears happy, 

 contented, and quite healthy. A larger, more spacious cage will be 

 constructed for occupation during hot weather, where he can be more 

 satisfactorily seen. 



From YelloiDstone National Park. — Two black timber wolves, in- 

 teresting from their rarity, were transferred from the Yellowstone 

 Park. 



Captured. — A raccoon, possibly a wild one, but more probably one 

 that had escaped, was caught in a trap. 



Loaned. — 3 mink and 7 martens were temporarily loaned, also 1 

 monkey and a parrot. 



LOSSES. 



Among the most important losses was that of the young male 

 African elephant, Jumbo II, a beautiful, active animal that was 

 bought from the Government Zoological Garden at Giza, Egypt, in 

 1913. He was then about 4 years old. The death of this valuable 

 animal was entirely unexpected, as he had always seemed in ex- 

 cellent health. A post-mortem examination, made by veterinarians 

 from the Bureau of Animal Industr}^, revealed a rupture of the 

 stomach, a tear 7 inches in length occurring along the great 

 curvature. Escape of the stomach contents had caused an acute 

 peritonitis. The cause of this rupture is quite obscure. The diet of 

 the animal had not been changed either in quantity or quality, and 

 the stomach had not been overdistended by food. Nor did an ex- 

 amination of the discharged material reveal any substances that 

 might have occasioned an active fermentation with considerable evolu- 

 tion of gas. The other viscera showed no gross pathologic changes. 



Other losses were a male lion, from softening of the brain, a fur 

 seal, a male California sea lion, a black leopard, from old age, a male 

 American bison, from pneumonia, a male and female nilgai, from 

 generalized tuberculosis; 38 animals were lost from attacks by cage 

 mates, by dogs (directly or indirectly), or through other accidents. 

 Amebic dysentery attacked some spider monkeys, recently received, 

 and caused the death of six of these animals. Post-mortem examina- 

 tions were made, as usual, by the Pathological Division of the Bureau 

 of Animal Industry, Department of Agriculture.^
