Jag tror att den passage du talar om är från Kongens återkomst (bok 6 specifikt). Frodo och Sam har just blivit borta från Cirith Ungol, och de går in i en patrull och hörs följande samtal.
They went two or three miles further, and the orc-hold was hidden from sight behind them; but they had hardly begun to breathe more freely again when harsh and loud they heard orc-voices. Quickly they slunk out of sight behind a brown and stunted bush. The voices drew nearer. Presently two orcs came into view. One was clad in ragged brown and was armed with a bow of horn; it was of a small breed, black-skinned, with wide and snuffling nostrils: evidently a tracker of some kind. The other was a big fighting-orc, like those of Shagrat's company, bearing the token of the Eye.
He also had a bow at his back and carried a short broad-headed spear. As usual they were quarrelling, and being of different breeds they used the Common Speech after their fashion.
Hardly twenty paces from where the hobbits lurked the small orc stopped. 'Nar!' it snarled. 'I'm going home.' It pointed across the valley to the orc-hold. 'No good wearing my nose out on stones any more. There's not a trace left, I say. I've lost the scent through giving way to you. It went up into the hills, not along the valley, I tell you.'
'Not much use are you, you little snufflers?' said the big orc. 'I reckon eyes are better than your snotty noses.'
'Then what have you seen with them?' snarled the other. 'Garn! You don’t even know what you're looking for.'
'Whose blame's that?' said the soldier. 'Not mine. That comes from Higher Up. First they say it's a great Elf in bright armour, then it's a sort of small dwarf-man, then it must be a pack of rebel Uruk-hai; or maybe it's all the lot together.'
'Ar!' said the tracker. 'They've lost their heads, that's what it is. And some of the bosses are going to lose their skins too, I guess, if what I hear is true: Tower raided and all, and hundreds of your lads done in, and prisoner got away. If that's the way you fighters go on, small wonder there's bad news from the battles.'
'Who says there's bad news?' shouted the soldier.
'Ar! Who says there isn't?'
'That's cursed rebel-talk, and I'll stick you, if you don't shut it down, see?'
'All right, all right!' said the tracker. 'I'll say no more and go on thinking. But what's the black sneak got to do with it all? That gobbler with the flapping hands?'
'I don't know. Nothing, maybe. But he's up to no good, nosing around, I'll wager. Curse him! No sooner had he slipped us and run off than word came he's wanted alive, wanted quick.'
'Well, I hope they get him and put him through it,' growled the tracker. 'He messed up the scent back there, pinching that cast-off mail-shirt that he found, and paddling all round the place before I could get there.'
'It saved his life anyhow,' said the soldier. 'Why, before I knew he was wanted I shot him, as neat as neat, at fifty paces right in the back; but he ran on.'
'Garn! You missed him,' said the tracker. 'First you shoot wild, then you run too slow, and then you send for the poor trackers. I've had enough of you.' He loped off.
'You come back,' shouted the soldier, 'or I'll report you!'
'Who to? Not to your precious Shagrat. He won't be captain any more.'
'I'll give your name and number to the Nazgûl,' said the soldier lowering his voice to a hiss. 'One of them 's in charge at the Tower now.'
The other halted, and his voice was full of fear and rage. 'You cursed peaching sneakthief!' he yelled. 'You can't do your job, and you can't even stick by your own folk. Go to your filthy Shriekers, and may they freeze the flesh off you! If the enemy doesn’t get them first. They've done in Number One, I've heard, and I hope it's true!'
The big orc, spear in hand, leapt after him. But the tracker, springing behind a stone, put an arrow in his eye as he ran up, and he fell with a crash. The other ran off across the valley and disappeared.
For a while the hobbits sat in silence. At length Sam stirred. 'Well I call that neat as neat,' he said. 'If this nice friendliness would spread about in Mordor, half our trouble would be over.'
