"Hearing Mir Jan's voice, I hurried forth, and found that his white pacing-camel was already saddled and that he sat in the front seat, prepared to drive. 'Up, Daoud Khan' he cried to me 'we go a-hunting'--and I sprang to the rear saddle even as the camel rose. 'Lead on, Moussa Isa, and track as thou hast never tracked before, if thou wouldst live,' said he to the Somali, a noted _paggi_,[30] even among the Baluch and Sindhi _paggis_ of the police at Peshawar and Kot Ghazi.

As we passed the shop of the European _hakim_, yes, the _kimmish_, my brother leapt down and entering the shop asked questions. Returning and mounting he said to me: ''Tis as I thought.
