On the 2rft, we fet out from Rafhid at two o’clock in the 
morning, and at a little paf eight arrived at Imhanzara,ha-_ 
ving gone moftly N. W. tonorth and by weft. This, too, is 
a {tation of the Arabs Daveina;, and there had been here 
large pools of water, the cavities, apparently dug by thehands

Tuis day, being the fifth of our journey, we had gone:
