Over it a trickling water dripped, through a wide cleft that seemed to have been carved out by a fall that had once been strong and full.
‘Indeed things have changed!’ said Gandalf. ‘But there is no mistaking the place. There is all that remains of the Stair Falls. If I remember right, there was a flight of steps cut in the rock at their side, but the main road wound away left and climbed with several loops up to the level ground at the top. There used to be a shallow valley beyond the falls right up to the Walls of Moria, and the Sirannon flowed through it with the road beside it. Let us go and see what things are like now!’
They found the stone steps without difficulty, and Gimli sprang swiftly up them, followed by Gandalf and Frodo. When they reached the top they saw that they could go no further that way, and the reason for the drying up of the Gate-stream was revealed. Behind them the sinking Sun filled the cool western sky with glimmering gold. Before them stretched a dark still lake. Neither sky nor sunset was reflected on its sullen surface. The Sirannon had been dammed and had filled all the valley. Beyond the ominous water were reared vast cliffs, their stern faces pallid in the fading light: final and impassable. No sign of gate or entrance, not a fissure or crack could Frodo see in the frowning stone.
‘There are the Walls of Moria,’ said Gandalf, pointing across the water. ‘And there the Gate stood once upon a time, the Elven Door at the end of the road from Hollin by which we have come. But this way is blocked. None of the Company, I guess, will wish to swim this gloomy water at the end of the day. It has an unwholesome look.’
‘We must find a way round the northern edge,’ said Gimli. ‘The first thing for the Company to do is to climb up by the main path and see where that will lead us. Even if there were no lake, we could not get our baggage-pony up this stair.’
‘But in any case we cannot take the poor beast into the Mines,’ said Gandalf. ‘The road under the mountains is a dark road, and there are places narrow and steep which he cannot tread, even if we can.’
‘Poor old Bill!’ said Frodo. ‘I had not thought of that. And poor Sam! I wonder what he will say?’
‘I am sorry,’ said Gandalf. ‘Poor Bill has been a useful companion, and it goes to my heart to turn him adrift now. I would have travelled lighter and brought no animal, least of all this one that Sam is fond of, if I had had my way. I feared all along that we should be obliged to take this road.’
The day was drawing to its end, and cold stars were glinting in the sky high above the sunset, when the Company, with all the speed they could, climbed up the slopes and reached the side of the lake. In breadth it looked to be no more than two or three furlongs at the widest point. How far it stretched away southward they could not see in the failing light; but its northern end was no more than half a mile from where they stood, and between the stony ridges that enclosed the valley and the water’s edge there was a rim of open ground. They hurried forward, for they had still a mile or two to go before they could reach the point on the far shore that Gandalf was making for; and then he had still to find the doors.
When they came to the northernmost corner of the lake they found a narrow creek that barred their way. It was green and stagnant, thrust out like a slimy arm towards the enclosing hills. Gimli strode forward undeterred, and found that the water was shallow, no more than ankle-deep at the edge. Behind him they walked in file, threading their way with care, for under the weedy pools were sliding and greasy stones, and footing was treacherous. Frodo shuddered with disgust at the touch of the dark unclean water on his feet.
As Sam, the last of the Company, led Bill up on to the dry ground on the far side, there came a soft sound: a swish, followed by a plop, as if a fish had disturbed the still surface of the water. Turning quickly
