"I and Kutaituchik watched as he carefully spread open the collar, pressing back two edges. Then, from within the collar he drew forth a thin, folded piece of paper, rence paper made from the fibers of the rence plant, a tall, long-stalked leafy plant which grows predominantly in the delta of the of Vosk. I suppose in itself, this meant nothing, but I naturally thought of Port Kar, malignant, squalid Port Kar, which claims suzerainty over the delta, exacting cruel tributes from the rence growers, great stocks of rence paper for trade, sons for oarsmen in cargo galleys, daughters for Pleasure Slaves in the taverns of the city. I would have expected the message to have been written either on stout, glossy-surfaced linen paper, of the sort milled in Ar, or perhaps on vellum and parchment, prepared in many cities and used commonly in scrolls, the process involving among other things the washing and lining of skins, their scraping and stretching, dusting them with sifted chalk, rubbing them down with pumice. "

"On river barges, for hundreds of pasangs, I had made my way down the Vosk, but where the mighty Vosk began to break apart and spread into its hundreds of shallow, constantly shifting channels, becoming lost in the vast tidal marshes of its delta, moving toward gleaming Thassa, the Sea, I had abandoned the barges, purchasing from rence growers on the eastern periphery of the delta supplies and the small rush craft which I now propelled through the rushes and sedge, the wild rence plants.
I noticed that one of these rence plants had, tied about it, below the tuft of stamens and narrow petals, a white cloth, rep-cloth."

Book 6, Raiders of Gor, page 5

"I was not particularly surprised at finding a bit of rep-cloth tied on the rence plant, for the delta is inhabited. Man has not surrendered it entirely to the tharlarion, the UI and the salt leach. There are scattered, almost invisible, furtive communites of rence growers who eke out their livelihood in the delta, nominally under the surzerainty of Port Kar. The cloth I found had probably been a trail mark for some rence growers."

Book 6, Raiders of Gor, page 6

"I now noted another bit of white re-cloth tied on the rence stem, larger than the first. I assumed it was another trail mark. I continued on. The calls of marsh gants, a kind of piping whistle, seemed more frequent now, and somewhat closer. I looked behind me, and to the sides. Yet, not surprisingly, because of the rence, the rushes and sedge, I could not see the birds."

Book 6, Raiders of Gor, page 6

"A kind of paper is made from rence. The plant itself has a long, thick root, about four inches thick, which lies horizontally under the surface of the water; small roots sink downward into the mud from this main root, and several 'stems', as many as a dozen, rise from it, often of the length of fifteen to sixteen feet from the root; it has an excrescent, usually single floral spike."

Book 6, Raiders of Gor, page 7

"Rence paper is made by slicing the stem into thin, narrow strips; those near the center of the plant are particularly favored; one layer of strips is placed longitudinally, and then a shorter layer is placed latitudinally across the first layer; these two surfaces are then soaked under water, which releases a gluelike substance from the fibers, melding the two surfaces into a single, rectangular sheet; these formed sheets are then hammered and dried in the sun; roughness in removed by polishing, usually with a smooth shell or a bit of kailiauk horn; the side of a tharlarion tooth may also be used in this work. The paper is then attached, sheet to sheet, to form rolls, usually about twenty sheets to a roll. The best paper is on the outside of the roll, always, not to practice deceit in the quality of the roll but rather to have the most durable paper on the outside, which will take the most weathering, handling and general wear. Rence paper comes in various grades, about eight in all. The rence growers market their product either at the eastern or western end of the delta. Sometimes rence merchants, on narrow marsh craft rowed by slaves, enter some pasangs into the delta to negotiate the transactions, usually from the western edge, that bordering the Tamber Gulf."

Book 6, Raiders of Gor, page 7

"The plant has many uses besides serving as a raw product in the manufacture of rence paper. The root, which is woody and heavy, is used for certain wooden tools and utensils, which can be carved from it; also, when dried, it makes a good fuel; from the stem the rence growers can make reed boats, sails, mats, cords and a kind of fibrous cloth; further it's pith is edible, and for the rence growers is, with fish, a staple in their diet; the pith is edible both raw and cooked; some men, lost in the delta, not knowing the pith edible, have died of starvation the the midst of what was, had they known it, an almost endless abundance of food. The pith is also used, upon occasion, as a caulking for boat seams, but tow and pitch, covered with tar or grease, are generally used."

Book 6, Raiders of Gor, page 7

"Rence paper is, incidentally, not the only type of writing material used on Gor. A milled linen paper is much used, large quantities of which are produced in Ar, and vellum and parchment, prepared in many cities, are also popular."

Book 5, Raiders of Gor, page 8

"She was standing on a small skiff of rence, not larger than my own rush craft, about seven feet long and two feet wide, fastened together, as mine was, with marsh vine; it, like mine, had a slightly curved stern and prow.
In her hand was a curved throwing stick, used for hunting birds. It is not a boomerang, which would be largely useless among the sedges and rushes, but it would, of course, float, and might be recovered and used indefinitely. Some girls are quite skilled with this light weapon. It stuns the bird, which is then gathered from the water and tied, alive, in the craft. The birds are later, on the rence islands, killed and cooked."

Book 6, Raiders of Gor, page 10

"Her gaze was clear; she had a dark blondish hair and blue eyes; her legs were a bit short, and her ankles somewhat thick; her shoulders were a bit wide perhaps, but lovely. She wore a brief, sleeveless garment of yellowish-brown rence cloth; it was worn well away from both shoulders to permit her freedom of movement; the brief skirt had been hitched up about her thighs that it might in no way bind her in her hunting. Her hair was tied behind her head with a strip of purple cloth, dyed re-cloth."

Book 6, Raiders of Gor, page 10

"At such times there is drinking of rence beer, steeped, boiled and fermented from the crushed seeds and the whitish pith of the plant."

Book 6, Raiders of Gor, page 18

"In a moment the woman had returned with a double handful of wet rence paste. When fried on flat stones it makes a kind of cake, often sprinkled with rence seeds."

Book 6, Raiders of Gor, page 25

"In the morning, before dawn, she had placed in my mouth a handful of rence paste."

Book 6, Raiders of Gor, page 28

"I had carried about bowls of cut, fried fish, and wooden trays of roasted tarsk meat, and roasted gants, threaded on sticks, and rence cakes and porridges, and gourd flagons, many times replenished, of rence beer."

Book 6, Raiders of Gor, page 44

"Before the feast I had helped the women, cleaning fish and dressing marsh gants, and then, later, turning spits for the roasted tarsks, roasted over rence-root fires, kept on metal pans, elevated above the rence of the islands by metal racks, themselves resting on larger pans."

Book 6, Raiders of Gor, page 44

"Holding half the rence cake in her mouth she unrolled her sleeping mat and then, as she had the night before, she unlaced her tunic and slipped it off over her head. She threw it to the corner of the hut, on her left, near her feet. She sat on the sleeping mat and finished the rence cake. Then she wiped her mouth with her arm, and slapped her hands together, freeing them of crumbs.
Then she unbound her hair, shaking it free.
Then she reclined on the mat, facing me, resting on her right elbow. Her left knee was raised. She looked at me. 'Serve my pleasure,' she said."
