On the subject of Ents

I have heard nothing of this in my own land, save only songs that tell how the Onodrim, that Men call Ents, dwelt there long ago; for Fangorn is old, old even as the Elves would reckon it.
- Legolas, The Riders of Rohan, TTT.

Yes, it is old, as old as the forest by the Barrow-downs, and it is far greater. Elrond says that the two are akin, the last strongholds of the mighty woods of the Elder Days, in which the Firstborn roamed while Men still slept. Yet Fangorn holds some secret of its own. What it is I do not know.
- Aragorn, The Riders of Rohan, TTT.

They found that they were looking at a most extraordinary face. It belonged to a large Man-like, almost Troll-like, figure, at least fourteen foot high, very sturdy, with a tall head, and hardly any neck. Wether it was clad in stuff like green and grey bark, or wether that was its hide, was difficult to say. At any rate the arms, at a short distance from the trunk, were not wrinkled, but covered with a brown smooth skin. The large feet had seven toes each. The lower part of the long face was covered with a sweeping grey beard, bushy, almost twiggy at the roots, thin and mossy at the ends. But at the moments the hobbits noted little but the eyes. These deep eyes were now surveying them, slow and solemn, but very penetrating. They were brown, shot with a green light. Often afterwards Pipin tried to describe his first impression on them.

One felt as if there was an enormous well behind them, filled up with ages of memory and long, slow, steady thinking; but their surface was sparkling with the present; like sun shimmering on the outer leaves of a vast tree, or on the ripples of a very deep lake. I don’t know, but it felt as if something grew in the ground - asleep, you might say, or just feeling itself as something between root-tip and leaf-tip, between deep earth and sky had suddenly waked up, and was considering you with the same slow care that it had given to its own inside affairs for endless years.’

Several Ents had already arrived. More were coming in down the other paths, and some were now following Treebeard. As they drew near the hobbits gazed at them. They had expected to see a number of creatures as much like Treebeard as one hobbit is like another (at any rate to a stranger's eye); and they were very much surprised to see nothing of the kind. The Ents were as different from one another as trees from trees: some as different as one tree is from another of the same name but quite different growth and history; and some as different as one tree-kind from another, as birch from beech, oak from fir.

"But I have an odd feeling about these Ents: somehow I don’t think they are quite as safe and, well funny as they seem. They seem slow, queer, and patient, almost sad; and yet I believe they could be roused. If that happened, I would rather not be on the other side."
- Merry, Treebeard, TTT.

"The Ents" excalimed Aragorn. "Then there is truth in the old legends about the dwellers in the deep forests and the giant shepherds of the trees? Are there still Ents in the world? I thought they were only a memory of ancient days, if indeed they were ever more than a legend of Rohan.."

"A legend of Rohan!" cried Legolas. "Nay, every Elf in Wilderland has sung songs of the old Onodrim and their long sorrow. Yet even among us they are only a memory. If I were to meet one still walking in this world, then indeed I should feel young again! But Treebeard: that is only a rendering of Fangorn into the Common Speech; yet you seem to speak of a person. Who is this Treebeard?"

"Ah! now you are asking much," said Gandalf. "The little that I know of his long slow story would make a tale for which we have no time now. Treebeard is Fangorn, the guardian of the forest; he is the oldest of the Ents, the oldest living thing that still walks beneath the Sun upon this Middle-Earth."
- The White Rider, TTT.

Certainly the forest of Fangorn is perilous - not least to those that are too ready with their axes; and Fangorn himself, he is perilous too; yet he is wise and kindly nonetheless. But now his long slow wrath is brimming over, and all the forest is filled with it. The coming of the hobbits and the tidings that they brought have spilled it: it will soon be running like a flood; but its tide is turned against Saruman and the axes of Isengard. A thing is about to happen which has not happened since the Elder Days: the Ents are going to wake up and find that they are strong.
- Gandalf, The White Rider, TTT.

Quotes from Treebeard

"The trees and the Ents," said Treebeard. "I do not understand all that goes on myself, so I cannot explain it to you. Some of us are still true Ents, and lively enough in our fashion, but many are growing sleepy, going tree-ish, as you might say. Most of the trees are just trees, of course; but many are half awake. Some are quite wide awake, and a few are, well, ah, well getting Entish. That is going on all the time."

"For Ents are more like Elves: less interested in themselves than Men are, and better at getting inside other things. And yet again Ents are more like Men, more changeable than Elves are, and quicker at taking the colour of the outside, you might say. Or better than both: for they are steadier and keep their minds on things longer."

"I do not like worrying about the future. I am not altogether on anybody's side, because nobody is altogether on my side, if you understand me: nobody cares for the woods as I care for them, not even Elves nowadays."

"When the world was young, and the woods were wide and wild, the Ents and the Entwives ... they walked together and they housed together. But our hearts did not go on growing in the same way: the Ents gave their love to things that they met in the world, and the Entwives gave their thought to other things, for the Ents loved the great trees, and the wild woods, and the slopes of the high hills; and they drank of the mountain-streams, and ate only such fruit as the trees left fall in their path; and they learned of the Elves and spoke with the Trees. But the Entwives gave their minds to the lesser trees, and to the meads in the sunshine beyond the feet of the forests; and they saw the sloe in the thicket, and the wild apple and the cherry blossoming in spring, in the autumn fields. ... for the Entwives desired order, and plenty, and peace."

"Hoom, hoom! Here we come with a boom, here we come at last!" called Treebeard when he caught sight of Bregalad and the hobbits. "Come, join the Moot! We are off. We are off to Isengard!"

"We Ents do not like being roused; and we never are roused unless it is clear to us that our trees and our lives are in great danger."

"It is sad that we should meet only thus at the ending. For the world is changing: I feel it in the water, I feel it in the earth, and I smell it in the air. I do not think we shall meet again."
