NATIVE CARABAO. 



The Indian buffalo or carabao of Guam is identical with the domes- 

 ticated carabao common throughout the Philippine Archipelago. (PI. 

 II, fig. 1 .) It is a slow, powerful animal, indispensable in the prepara- 

 tion of the muddy rice fields, and well adapted to general farm work 

 requiring great strength rather than speed and especiall}^ in wet, cloudy 

 weather or during the cool hours of the day. Carabao, however, do not 

 withstand high temperatures as well as do cattle. This is probably 

 due in part at least to a less delicate anatomical apparatus in the 

 former for regulating the body temperature. The carabao has a 

 thick, tough skin, and does not sweat freely, even when at hard work 

 and on the warmest days of the year. The normal body temperature 

 of the carabao is probably somewhat lower than that of cattle. The 

 writer, while connected with the Philippine bureau of agricuhure, 

 had opportunity during the early summer of 1907 to take and record 

 the temperatures of 373 carabao in central Luzon. These animals 

 were apparently in normal health, and were of various ages and of 

 both sexes. Their temperatures, taken at all hours of the day, 

 averaged 100.7° F. The body temperature of the small calf is 

 generally considerably higher than that of older animals, often stand- 

 ing at 102° or higher. Exertion on a warm day seems to cause a 

 marked rise in the temperature of these animals. Temperatures of
