midnight
`` Sorry , but before I could give any orders I 'd need a few myself . '' At eleven o'clock that night Dr. Gitney arrived , with saddle-bags full of medicines and other necessaries . He saw Blaisdell , and pronounced the assistant engineer a very sick man . Shortly after midnight Mr. Thurston rode into camp . He tottered from saddle and reeled until Tom , on the lookout for him , ran forward and supported the chief engineer to his tent . Then Dr. Gitney was sent for and came . `` Your chief has mountain fever , too , '' said the medical attendant to Tom , after stepping outside the tent .
