In Animal Farm, how is Mr. Jones portrayed in the first chapter?

Mr. Jonas is portrayed as taking advantage of his animals.

Manor Farm is not a very happy place for the animals.  The farmer, Mr. Jones, is at best negligent and at worse abusive.  He has a habit of getting drunk and forgetting to take care of his animals, or leaving the farm for long periods of time when his animals need attention.

Mr. Jonas is portrayed as taking advantage of his animals.

Manor Farm is not a very happy place for the animals.  The farmer, Mr. Jones, is at best negligent and at worse abusive.  He has a habit of getting drunk and forgetting to take care of his animals, or leaving the farm for long periods of time when his animals need attention.

Old Major vilifies Jonas in his speech to the animals about why they should get rid of the humans.  He explains that Jones is taking advantage of the animals, and that everything they have is stolen by him—including often their lives.

And what has happened to that milk which should have been breeding up sturdy calves? Every drop of it has gone down the throats of our enemies. And you hens, how many eggs have you laid in this last year, and how many of those eggs ever hatched into chickens? The rest have all gone to market to bring in money for Jones and his men.  (Ch. 1)

Old Major also describes how animals are killed before they can grow old, or the ones who do grow old are killed as soon as they can no longer work.  No animal gets a peaceful and quiet retirement in his old age.

You, Boxer, the very day that those great muscles of yours lose their power, Jones will sell you to the knacker, who will cut your throat and boil you down for the foxhounds. As for the dogs, when they grow old and toothless, Jones ties a brick round their necks and drowns them in the nearest pond. (Ch. 1)

The animals all live this terrible existence because of the tyranny of man.  Man forces them to work for him, takes their young, and kills them whenever he feels like it.  The animals do all of the hard work, and Jones does nothing.  All he does is get drunk and forget to feed the animals or milk the cows.

Old Major's rhetoric is very convincing.  Soon Jones is too drunk to feed the animals and they decide to revolt.  They kick the humans out and take over the farm.  Unfortunately, many of the abuses Old Major described continue under the new regime of pigs.
