Where is foreshadowing found in "The Veldt" by Ray Bradbury?

George and Lydia's violent death in the nursery being eaten by lions is foreshadowed several times.

Both parents are uneasy about the nursery and the strange hold the images of the veldt have on their children. One day, as his concern grows over the nursery, George bends down to find his wallet in the corner of that room:

The smell of hot grass was on it and the smell of a lion. There were drops of saliva on it, it bad been chewed, and there were blood smears on both sides.

This clearly foreshadows the violent end awaiting George.

Likewise, when the worried George and Lydia bring in the psychologist, Dave McClean, to assess the situation, he finds Lydia's bloodied scarf lying in the nursery, foreshadowing that Lydia's end is as dire as her husband's.

The parents also hear screams from the nursery:

Two screams. Two people screaming from downstairs. And then a roar of lions.

The strange and dishonest behavior of the children foreshadows as well the grisly ending. When they come in for dinner one day, the children's eyes are hard and bright, like marbles, in a way that seems eerie and inhuman. They then lie when confronted about the veldt scenes in the nursery. Peter says, "I don't remember" an Africa being there, a statement that parents know is a blatant falsehood. The children are, overall, subtly hostile and fearless towards their parents.

All of this builds up a sense of foreknowledge about what is going to happen so that we are not surprised when the parents "disappear" when locked by the children in the nursery.

Where is foreshadowing found in "The Veldt" by Ray Bradbury?

There is immediate foreshadowing in the opening lines of Ray Bradbury's "The Veldt":

'George, I wish you'd look at the nursery.'

'What's wrong with it?'

'I don't know....I just want you to look at it, is all, or call a psychologist in to look at it.'

With this last line of Lydia Hadley (whose name, interestingly, has the past tense of have as part of it), there is a sense of foreboding, not just for the parents, but also for the children since there is the suggestion that they are psychologically altered by this virtual reality of the African jungle.  The impending danger is foreshadowed in, not only the charging lions, but more subtlely in the "green-yellow eyes" of these virtual animals, whose evil influence supercedes the parental one.  For, the children now have become obsessed with their virtual world, rather than the real one:  "They live for the nursery." 

Published in 1950, Bradbury's story not only foreshadows the destruction of the family unit of the Hadleys, but it hints at the dangers of virtual reality that are a present threat to the detachment of people from friends and family in modern society.

Where is foreshadowing found in "The Veldt" by Ray Bradbury?

There is foreshadowing in this story in what happens every time George and Lydia go into the room in the first parts of the story.  We know (having read the whole thing) that they are going to end up being killed in the room.  We can see this foreshadowed when they go look at the room earlier in the story.

When the do this right at the beginning of the story, something has been killed, which may foreshadow that they will be. More obviously, the lions charge them and they feel like they have barely escaped with their lives.  This foreshadows what will actually happen to them.

Then, later on, we see George go into the room and find his old wallet.  That is more foreshadowing.  Something similar will happen to Lydia later.

What elements of foreshadowing in "The Veldt" suggest something bad happening in the nursery?

Every time George and Lydia visit the nursery and see the veldt scene playing, their deaths are foreshadowed. They find George's chewed wallet and Lydia's bloody scarf on the floor of the nursery. The lions even seemingly come running at them as if attacking them early in the story, foreshadowing their end and sending them screaming from the nursery:

And here were the lions now, fifteen feet away, so real, so feverishly and startlingly real that you could feel the prickling fur on your hand, and your mouth was stuffed with the dusty upholstery smell of their heated pelts . . . and the sound of the matted lion lungs exhaling on the silent noontide, and the smell of meat from the panting, dripping mouths.

The lions stood looking at George and Lydia Hadley with terrible green-yellow eyes. . . .The lions came running at them.

The whole look and feel of the veldt is ominous and makes the parents uneasy. It is hot, dry, and predatory.

Further, the children lie to their parents about the nursery. They even change the scenery on the view screens to encourage the parents into thinking they are not always watching the veldt. They behave coldly to the parents, foreshadowing the disregard and lack of feeling that will allow them to lock the parents in the nursery to be consumed by the lions.

What are some examples of foreshadowing in "The Veldt"?

In Ray Bradbury's short story "The Veldt," there are many examples of foreshadowing. Foreshadowing is a literary device that authors use to give hints to upcoming events in the story. The first example comes at the beginning of the story:

“George, I wish you’d look at the nursery.

“What’s wrong with it?”

“I don’t know.”

“Well, then.”

“I just want you to look at it, is all, or call a psychologist in to look at it.”

“What would a psychologist want with a nursery?”

“You know very well what he’d want.” 

It's clear from this conversation that Lydia is worried and that her concern is not a simple problem. She also hints that George knows what the problem is, as well. This grabs the reader's attention and makes them want to read on to find out what could be so wrong with a nursery that a psychologist would need to be called in to investigate. 

The nursery in this story is a high-tech, interactive room that will project all the sensory information for whatever the children think about. If they think about a jungle, for example, they will see the jungle foliage, hear the animals, and even smell the smells located in the jungle. George and Lydia's children, Peter and Wendy, have been thinking about Africa lately. Their parents are disturbed because the sounds and smells are intense, the scenes violent. They don't want to see their "innocent" children interacting with such a raw and savage reality. 

"The lions came running at them. Lydia turned suddenly and ran. Without thinking, George ran after her. Outside in the hall, after they had closed the door quickly and noisily behind them, he was laughing and she was crying. And they both stood shocked at the other’s reaction. “George!”

“Lydia! Oh, my dear poor sweet Lydia!” “They almost got us!” 

The quote above foreshadows the fact that the children's fantasy of Africa and the lions is related to the children's plot to harm their parents. 

"Remarkable how the nursery read the thoughts in the children’s minds and created life to fill their every desire. The children thought lions, and there were lions. The children thought zebras, and there were zebras. Sun – sun. Giraffes – giraffes. Death and death. That last. He ate the meat that the table had cut for him without tasting it. Death thoughts. They were awfully young, Wendy and Peter, for death thoughts. Or, no, you were never too young, really. Long before you knew what death was you were wishing it on someone else. When you were two years old you were shooting people with toy guns." 

George is starting to understand that the children's thoughts are dark at this point in the story, but he still hasn't made the connection that these dark thoughts are directed toward him and his wife. 

Later, when they're discussing the nursery being stuck on the veldt despite their efforts to change it to something more mild, Lydia observes this about the nursery: 

“Or it can’t change,” said Lydia, “because the children have thought about Africa and lions and killing so many days that the room’s stuck in a pattern it can’t get out of.”

The nursery is supposed to change depending on what the user is thinking. George and Lydia try to think positive thoughts and even give the nursery direct commands to change, but it won't. This foreshadows the plot of the children. 

There are more examples of foreshadowing, as well. The parents heard screams coming from the veldt, and they recognize that the screams sound familiar. This foreshadows their own screams as the lions attack them. There is also foreshadowing with the old wallet and bloody scarf that belong to George and Lydia. The lions have been given these items in order to find the parent's scent for an attack.
