Early Arabian authors are far more explicit, and we gather from Makrisi, Ibn Khaldun, and others, something more definite about Dhofar and the frankincense trade, and of the prince of this district who had the monopoly of the trade, and punished its infringement with death. These writers, when compared with the classical ones, assist us greatly in identifying localities.

The Portuguese knew about Dhofar and its productions, for Camoens, in his Tenth Lusiad, 716, writes:

'O'er Dhofar's plain the richest incense breathes.'

But not until Dr. Carter coasted along here some fifty years ago was it definitely known that this was the chief locality in Arabia which produced the drug.

Myrrh, too, grows in large quantities in the Gara range, and we obtained specimens of it in close proximity to the frankincense-tree. The gum of the myrrh-tree is much redder than ordinary gum Arabic, whereas the frankincense gum is considerably whiter. The commerce of Dhofar must have been exceedingly rich in those ancient days, as is evidenced by the size and extent of the Sabæan ruins on the plain. They are the most easterly ruins which have been found in Arabia of the Sabæan period, and probably owe their origin entirely to the drug trade.

For the first few days of our journey, we suffered greatly from the unruliness of the camels. They danced about like wild things at first, and scattered our belongings far and wide, and all of us in our turns had serious falls, and during those days, boxes and packages kept flying about in all directions. Imam Sharif had his travelling trunk broken to pieces and the contents scattered right and left, and some treasured objects of jewellery therein contained were never recovered. So scarce did rope become during our journey, that the Bedouin had actually to take the leather thongs which bound their matted locks together, to lead the camels with, and rope was almost the only thing they tried to steal from us while we were in their company. At length our means of tying became so exhausted that we had to send a messenger back to buy rope from Wali Suleiman, and obtained a large sackful for two reals.

Our new supply of rope was made of aloe-fibre, barely twisted in one thin strand, and at every camp we had to set up a rope-walk to make ropes that would not break. The Garas were always cutting off short bits to tie round their hair or their necks. The servants, headed by Lobo, had to be very sharp in picking up all the pieces lying about after unloading, or we should soon have been at a loss again.

We originally understood that Sheikh Sehel was going to take us up to the mountains by a valley still farther west, but for some reason, which we shall never know, he refused; some said the Mahri tribe was giving trouble in this direction, others that the road was too difficult for camels. At any rate, we had partially to retrace our steps, and following along the foot of the mountains, found ourselves encamped not so many miles away from Al Hafa.
