It will have extended from about Damaghan (long.

54 deg.

10') upon the west, to the Heri-rud upon the east, and have comprised the modern districts of Damaghan, Shah-rud, Sebzawar, Nishapur, Meshed, Shebri-No, and Tersheez.
Its length from east to west will have been about 300 miles, and its average width about 100 or 120.

It will have contained an area of about 33,000 square miles, being thus about equal in size to Ireland, Bavaria, or St.Domingo.
The character of the district has been already stated in general terms; but some further particulars may now be added.

It consists, in the first place, of a mountain and a plain region--the mountain region lying towards the north and the plain region towards the south.
