Prong-Horned Antelope Herd. — Although it is risky to make at 

 this time any statement regarding our herd of prong-horned an- 

 telope, nevertheless our success with it during the past year gives 

 us reason to hope that this species can survive here without be- 

 ing attacked by gastro-enteritis. 



A year ago last summer we started a new herd of antelope, 

 with ten specimens, about one-half of them adult. Owing to the 

 loss of all those previously allowed to graze on green grass in 

 the range, we decided to try the experiment of keeping a herd 

 in a corral containing no grass, feeding it chiefly on dry food, 

 and carefully regulating the supply of green grass. 

 • This policy was carried out, and the result has been very 

 gratifying. There has been no occurrence of gastro-enteritis. 

 Three deaths have occurred in the herd, two being due to acci- 

 dents, and one to fighting. The remaining seven animals of the 

 original herd are in as fine physical condition as if they had all 

 this time been living in their home country. They are fat, in 

 fine pelage, lively, and so vigorously playful that their attentions 

 to their keepers are a positive annoyance. 



Our experiments with moose, mule deer, and Columbian 

 black-tailed deer have not been as successful as we had hoped, 

 on account of all three of these specimens having been persist- 

 ently subject to gastro-enteritis, a disease which in them seems 

 incurable. Pending further studies into the causes and preven- 

 tion of that malady, we will not now renew our stock of moose ; 

 but we expect to do so at a later period.
