Danny Dunn and the Swamp Monster by Jay Williams and Raymond Abrashkin, 1971.
Professor Bullfinch receives a cryptic message, which he says is written in the style of a telegram (he calls it “cablese” – a way of shortening messages because people pay for telegrams by the word). As Professor Bullfinch and Danny study the message further, they can draw more conclusions about the sender, who is not specified. They know it’s someone with money because the hotel it was sent from is expensive. From one of the terms used, they think the sender is a scientist, and because he sent a message written to be a telegram as a letter, he’s probably absent-minded. That description seems familiar to Professor Bullfinch.
Then, a strange man comes to the door who seems oddly distracted and confused. He greets Danny as if he were an old friend, but Danny has no idea who he is. He thinks the man is crazy, but Professor Bullfinch recognizes him as his old friend Dr. Benjamin Fenster. Of course, Dr. Fenster is the person who sent the confusing message. It turns out that Dr. Fenster meant to send that message to Dr. Ismail at the University of Khartoum, but he accidentally got it mixed up with the message he was going to send to Professor Bullfinch. Dr. Fenster is an absent-minded professor type, and he’s always doing things like that. Although, he does correct Danny when he mentions this, saying that he’s not actually a professor, and it’s not so much that he’s absent-minded so much as that he has a lot to think about and can’t think of everything at once.
Their conversation is interrupted when something goes wrong with the experiment that Professor Bullfinch and Danny were working on before Dr. Fenster arrived. A warning goes off, and Professor Bullfinch yells to Danny to shut off the machine. However, Danny can’t find the shut off switch, so he panics and pulls an electrical cord, sending an electrical current through the project before Professor Bullfinch turns off the switch. When they examine the results of the experiment, they’re surprised. Professor Bullfinch was trying to develop a new polymer, but the accident with the machine and the electrical current have turned the polymer into a superconductor and a very powerful ring magnet with a circular magnetic field.
While they’re examining the results of the experiment, Dr. Fenster wanders off, lost in thought. Danny worries if he’ll be okay, wandering around on his own, but Professor Bullfinch says that he’ll be fine. Dr. Fenster often does this when he’s thinking something through. Danny’s friends, Joe and Irene, arrive, commenting on seeing a man who was acting strangely and wondering if there’s something wrong with him. Danny explains to them who Dr. Fenster is and tells them about the ring magnet. Then, Dr. Fenster bursts back in, very excited, because he’s figured something out. He thinks the magnetic polymer ring might be the solution to a problem he’s been trying to solve.
Dr. Fenster is a zoologist, and one of his projects is to investigate accounts of legendary animals. Although many scientists tend to disregard stories of unknown animals as purely legendary, sometimes, they turn out to be previously unreported/undiscovered species. (“Undiscovered” in the scientific sense. Obviously, people have seen them, or they wouldn’t tell stories about them. These are species that haven’t been officially documented as having been discovered among the scientific community.) Investigating rare or possibly unknown species is what Dr. Fenster does.
Dr. Fenster is currently investigating reports of a creature called the lau, which apparently lives in swampy areas around the source of the Nile River in Uganda. The lau is supposed to be an enormous serpent with tentacles on its head. The legend around it says that if a person sees the lau first, the lau will die, but if the lau sees the person first, the person will die. When the others ask him if he thinks that’s real, Dr. Fenster says that he thinks that’s more metaphorical, like when someone says they felt petrified, it doesn’t mean that they literally turned to stone, or if someone says that their blood froze, it just means that they felt horrified. He thinks that the idea is that a serpent could kill a person, if they didn’t see it and disturbed it, but if the person saw the serpent first, they would kill it to avoid the threat.
The problem that Dr. Fenster has been trying to solve is how to move around the swamp and keep the area under observation during the night as well as the daytime, without possibly disturbing the creature he’s trying to find. It’s difficult to get around that swampy area in daylight, but it’s even more difficult at night, and he doesn’t want to use lights because that could frighten away the lau. He’s been thinking that he would like to mount some specialized cameras in certain strategic areas, but he couldn’t figure out how to mount them, and the cables he would have to use would be long and heavy. Having seen what the magnetic polymer can do, though, he thinks that could be the solution to the problem. It doesn’t weigh much itself, but when they test it, they discover it can support the weight of a grown man.
Dr. Fenster invites Professor Bullfinch and the children to join him on his expedition. He’s independently wealthy, and he can afford to pay for all them to come along. However, Danny’s mother has reservations about how safe this expedition is, and she can’t imagine that Joe or Irene’s parents will allow them to go on the trip, either. It takes time for Dr. Fenster to persuade the children’s families that the trip is safe enough for them. Eventually, they give in and allow the children to travel to Africa as a special Christmas present. Dr. Fenster doesn’t have any time limit on his own investigations, but the parents limit the children to only two weeks.
When they get to Africa, the first place that Dr. Fenster takes them is to Khartoum University in Sudan, where he introduces them to Professor Ismail, the Director of the Department of Zoology. Professor Ismail has helped Dr. Fenster with travel arrangements, equipment for the expedition, and the necessary government permits. Danny asks Professor Ismail what he thinks about the stories of the lau and whether it could be something like a dinosaur that has somehow survived. Professor Ismail says that many things are possible because there known oddities among animals, like the platypus, which lays eggs even though it’s a mammal. He shows them a fish called clarias lazera, which has the rare ability to leave water and live on land for a period of time.
The children get something to eat at a local cafe and talk excitedly about what the lau could really be and how its discovery could be “the most important discovery of the century.” Irene notices that a man in the cafe looks very interested in what they’re saying and follows them when they leave.
When the expedition reaches the site Dr. Fenster wants to investigate, they persuade some of the Nuer people who live there to show them where they’ve see the lau. They are initially reluctant and warn them that the lau is dangerous, but they do show them an area, and the members of the expedition start setting up cameras to watch it. As they begin exploring, they do find large trenches that are like the paths supposedly left by the giant serpents.
Dr. Fenster explains to the disappointed children that he won’t take them along to confront the lau directly, even if they do find it because of the possible danger. He and Professor Bullfinch will handle the creature, using the tranquilizer gun that Dr. Fenster brought along. They plan to have the children watch on the monitors and keep an eye on the base camp. However, the children see something unexpected when they’re looking at the monitors: the same strange man who was following them in Khartoum. Who is he and why has he followed their expedition?
When the children tell Professor Bullfinch and Dr. Fenster about him, they meet up with the man, and he introduces himself as a rare animal collector. He offers to join their expedition and help them, but Dr. Fenster refuses. One of the Nuer recognizes the man as a disreputable character who would do anything for money, and Dr. Fenster thinks he’s a poacher, who would try to capture rare animals and sell them, rather than simply study them scientifically. It seems that, aside from protecting themselves from the possibly dangerous lau while they study it, they might also have to protect the lau.

My Reaction and Some Spoilers
The lau is a cryptid in the real world as well as in the story, and the details Dr. Fenster offers about where it supposedly lives and historical mentions of the creature are accurate. Accounts of what the lau might actually be in real life vary. It could be a type of python or a very large fish, like a catfish. In the story, when they do find the lau, it turns out to be an enormous catfish, the kind that can live without water for a time and move on land, but it also turns out to be electrical, like an electric eel. Professor Bullfinch and Dr. Fenster decide that it’s related to the malapterurus, which is in keeping with real world theories about the lau.
The story makes some good points about known animals in the real world that are considered oddities because they have qualities that don’t normally apply to other animals of their type, like how the platypus is an egg-laying mammal. Just because something sounds unusual doesn’t mean that it’s impossible. There are wide variations among creatures in the animal kingdom. I thought it was interesting that they brought up the clarias lazera, which is a type of catfish that can live and move on land. A similar type of catfish that can live and move on land appeared in the children’s mystery book The Mystery of the Other Girl.
I’m not sure whether the accident that produced the magnetic polymer makes any reasonable scientific sense, but there a few interesting facts in the story. When they get to Africa, Dr. Fenster explains to them that there are actually two Nile rivers – the White Nile and the Blue Nile. They get their names because the soil they pass through gives them each a different color.
There are some words of another language included in the story when they reach Uganda, but I’m honestly not sure whether they’re real words or just made up to make it seem like Dr. Fenster can speak the local language. I tried putting them through Google translate to see if it could recognize them as anything, but it came out as nonsense. However, it’s supposed to be a language spoken by the Nuer people, so it might be something that Google translate doesn’t know.
Sometimes, I’m a little suspicious when I encounter obscure foreign words in old children’s books. I’ve read other old children’s books which use made-up words in place of an actual foreign language, probably because the writers didn’t know how to write something in a real foreign language but they wanted something that looked like it could be from another language. They were probably also acting with the assumption that kids wouldn’t know the difference, so it wouldn’t matter. I could be doing these authors a disservice by being a little suspicious here. Perhaps they did some extra research to learn a few phrases in a language that would be very obscure in the United States. It’s just that, having seen fakery elsewhere, it’s something I find myself looking for when I see instances of languages that would be difficult to fact-check.
Faking words in a real spoken language is less tolerated in the 21st century than it used to be, especially in a book that’s supposed to have educational qualities, so I hope they didn’t attempt to do that. Faking lesser details in a fiction book that’s supposed to have some real facts tends to cast suspicion on just how many of the other “facts” in the book are fake. This is an adventure story, not a textbook, so it’s true that some creative license is allowed. I still don’t know if their magnetic polymer concept is at all plausible, but the Danny Dunn stories are science fiction adventures, so some creative license there is allowed. However, readers like to feel that they can trust a certain amount of supporting detail to be correct. It’s also considered a cultural insult to use fake nonsense words in place of actual words from a language people really speak. Hopefully, that’s not the case here, but I wanted to point out the concept so readers can see how the use of real words strengths a story while faking them weakens it.
The story offers about the Nuer people, but I’m not sure how accurate they are. I don’t know where the authors got their information. They say that Nuer people don’t have chiefs and don’t follow orders from anybody, but according to the eHRAF World Cultures collection through Yale University, their clans do have headmen, and they also have sub-chiefs.
