A 12-year CNN veteran, Jeanne Meserve, openly but quietly wept during a long 10 minute telephone interview on Monday evening.

Meserve's report on CNN's NewsNight programme became quieter and quieter as she reflected on what she had seen in the American south as Hurricane Katrina flooded cities and destroyed homes. She described a hellish scene. Her emotion was neither false nor unnecessarily dramatic; the report was quiet and genuine, and the following excerpt from the CNN transcript barely captures the essence of the reporting.

MESERVE: As we were driving back, we passed scores of boats, Fish and Wildlife boats that they brought in. They're flat bottomed. They've obviously going to put them in the water just as soon as they possibly can and go out and reach the people who are out there who desperately need help.

We watched them, some of them, come in. They were in horrible shape, some of them. We watched one woman whose leg had been severed. Mark Biello, one of our cameramen, went out in one of the boats to help shoot. He ended up being out for hours and told horrific tales. He saw bodies. He saw where -- he saw other, just unfathomable things. Dogs wrapped in electrical -- electrical lines who were still alive that were being electrocuted.

The police are having radio problems. At least they were earlier this evening. They didn't have enough boats. They put out an appeal to various police who had personal boats to bring them to the scene. But the problem was the people who had the boats couldn't get to the boats to bring them to the scene to go out and rescue the people.

People are out there tonight. One of the EMS workers told us that the water is driving, and I can tell you that when we came back into the city tonight, it certainly was higher here. Whether it's rising in that neighborhood as much as it has here, I don't know.

So far, it is estimated that 68 people have died from the storm so far, although that figure is expected to rise.

BROWN: Is there any sense of -- that there's triage, that they're looking to see who needs help the worst? Or they're just -- they were just getting to whomever they could get to and get them out of there?

MESERVE: I had the distinct impression they were just getting to whoever they could get to. I talked to one fire captain who'd been out in his personal boat. He said he worked an area probably 10 square blocks. He'd rescued 75 people. He said in one instance there were something like 18 people in one house, some of them young. One, he said, appeared to be a newborn.

And he said other boats were working the same area at the same time, also picking up large numbers of people. And he doesn't believe they got all of them. And that's just one 10-block area. I don't know how big the area is. I haven't been able to see any footage from the air, but it appears to go on forever. It's hard for me to comprehend how many people might be out there and how many people's lives are in jeopardy or how many people may already be dead.

BROWN: It's -- it's -- just stay with me for a bit, OK? It's what is -- for everybody now, what's very difficult is there isn't what we refer to in the business as a wide shot. We can't get -- authorities can't get, we can't get, we can't give to those of you who are watching tonight that wide picture of what these scenes are like.

Can you -- what kind of neighborhoods are we talking about? Are these middle class neighborhoods? Are they -- the homes structurally sound? What are we talking about?

MESERVE: Well, the area where I was, and I don't know what the other neighborhoods are like, but this was a poor neighborhood. These were very humble homes. Most of them appeared to be only one story high with, then, some small attic space above them. These people are people of not much means. Some of them, I would guess, do not have cars and didn't have the option of driving away from here. Some of them, I would guess, did not have the money that would have bought them a hotel room.

Meserve added that her cameraman Mark Biello broke his foot at 9am Monday morning but continued not only filming but helping with the rescue operation.

BROWN: Our thanks to you for your efforts. It -- you don't need to hear this from me, but you know, people sometimes think that we're a bunch of kind of wacky thrill seekers doing this work, sometimes, and no one who has listened to the words you've spoken or the tone of your voice could possibly think that now. We appreciate your work.

MESERVE: Aaron, thank you. We are sometimes wacky thrill seekers. But when you stand in the dark, and you hear people yelling for help and no one can get to them, it's a totally different experience.

BROWN: Jeanne, thank you. We'll talk later tonight. Thank you.

Jeanne Meserve, been on the team for almost 15 years, I think. She is a very tough, capable, strong reporter, and she met her match on a story tonight.
