The Merchants have, in the last few years, on certain trade routes, between Ar and Ko-ro-ba, and between Tor and Ar, established palisaded compounds, defensible stockades. These, where they exist, tend to be placed approximately a day's caravan march apart. Sometimes, of course, and indeed, most often, the caravan must camp in the open. Still, these hostels, where they are to be found, are welcome, both to common merchants and to slavers, and even to travelers. Various cities, through their own Merchant Castes, lease land for these stockades and, for their fees, keep their garrisons, usually men of their own cities, supplied. The stockades are governed under Merchant Law, legislated and revised, and upheld, at the Sardar Fairs. The walls are double, the interior wall higher, and tarn wire is strung over the compound.

Several weeks ago in Ar there had been some hints of an attempt on the part of the Ubarate, as a social-control procedure, to facilitate its governance, a venture doubtless emanating from Cos, which had reason to fear an alert, healthy foe, to reduce the vitality and virility of the men of Ar, to further crush and depress them. This was to be done under the initial guise of sumptuary laws, ostensibly to limit the adornment and display of slaves, as though there could be much of that sort of thing in the defeated city. This was to be followed by legislation encouraging, and then apparently to later require, more modest garmenture for slaves. There were even suggestions of attempting to regulate the relationships obtaining between masters and slaves.
