Miss Bianca in the Salt Mines by Margery Sharp, illustrated by Garth Williams, 1966.
This book is part of the Rescuers series.
When this story begins, Miss Bianca, who is Perpetual Madam President of the Mouse Prisoners’ Aid Society, is evaluating candidates for the Tybalt Stars award, which is given for mice who are brave in the face of cats. Bernard, the secretary of the society, is helping her. Each of the candidates is undeniably brave, but Miss Bianca notices that each of them also had a self-serving motive behind their bravery, which seems disappointing for a benevolent society. When they stop for lunch and Bernard goes to fetch some salt for them, he finds a note in the salt that says, “Someone please get me out of the salt mines.” The note is signed “Teddy (age 8).” Naturally, Miss Bianca is eager to help the poor boy! Bernard is a little more doubtful about the mission because the salt mines are about a thousand miles away, extremely dangerous, and extremely well guarded. Nevertheless, the Mouse Prisoners’ Aid Society cannot refuse to help a prisoner, and neither can its President.
Soon, Miss Bianca has members of the society trying to learn anything they can about a missing boy named Teddy, but apparently, no one has reported a boy by that name or age as missing. Bianca uses the lessons of the boy who owns her to learn more about the salt mines and how to get there. In order to get to the salt mines, they’d have to go by train, and it’s a very dangerous route. At the next meeting of the society, Miss Bianca asks for volunteers to go rescue Teddy, but everyone is reluctant to go, and many members of the society don’t like it that Miss Bianca doesn’t even seem to have any facts about Teddy or his situation that could help them. Miss Bianca says that, even though she can’t be more specific about Teddy’s background or how he came to be in the salt mines, the important fact is that he shouldn’t be there, and he needs help getting out. Since no one else wants to volunteer for the rescue mission, Miss Bianca says that she’ll go herself, and of course, Bernard insists on coming with her.

To Miss Bianca’s surprise, her biggest opponent, a curmudgeonly mouse called the Professor (his real name is George) who teaches mathematics, also volunteers to join the mission. Bernard and Miss Bianca are even more surprised when the Professor insists on bringing his friend Caerphilly along. Caerphilly is very elderly, but he’s also a professor of geology. Caerphilly has never actually been to the salt mines before, but he’s always wanted to see them and study them. Bernard and Miss Bianca aren’t sure that Caerphilly is up to handling the dangers that they’re likely to encounter on the mission. Miss Bianca reminds Caerphilly that this is supposed to be a rescue mission, not a scientific expedition. Caerphilly is unconcerned, saying that they can handle the rescue, and he’ll handle the science. Miss Bianca says that the Professor should warn his friend just what risks a rescue mission involves, but the Professor is also unconcerned, saying that the geology department at the university thinks too much of itself, and he wouldn’t mind seeing his friend chased by bloodhounds. (Some friend he is.) Miss Bianca is concerned both because of the danger and because their self-serving motives are just what she was concerned about before.

In spite of that, they decide to proceed with the mission, bringing the two professors. They take some time to make their preparations. Bernard and Bianca research the trains they’ll need to take. The Finance Committee allows them to take along the society’s Treasure – there’s only one, a single gold coin they found in a ruined building. Teddy might need this to pay for his train fare after they get him out of the mines. The Ladies’ Guild also knits mittens for the unfortunate boy because the salt mines are reportedly very cold. Miss Bianca tells the boy she lives with not to worry if he doesn’t see her for a week or so because she’s going to be writing an epic poem and needs privacy.
As they finally set out on their mission, the Professor is pessimistic, but the train journey is uneventful. When they arrive at the salt mines’ train station, it’s a very bare and gloomy building. Bernard finds a wooden door with some steps heading down.
At the bottom of the steps, they find themselves in an underground cavern filled with stalactites and stalagmites. There is also an underground lake surrounded by crusts of salt. The Professor realizes that they have entered the salt mines through a disused and forgotten entrance. In the distance, they hear the sounds of prisoners mining the salt.

It’s a long walk to the active part of the mine, but along the way, they make an important discovery – a mouse-sized city carved out of salt! Each of the buildings in the miniature town are unique and resemble famous buildings from around the world. Miss Bianca thinks that the buildings were probably carved by prisoners who made buildings to resemble the places where they used to live. It’s the perfect place for the mice to stay, though.
Bernard, inspired by this strange place, tries to write a poem for the first time in his life, which isn’t very good. Miss Bianca tries to be nice about it, but he can tell that she doesn’t like it. Bernard is upset enough to try to drown himself (that part of the story struck me as rather shocking, although it’s handled so matter-of-factly as just a product of the weird atmosphere of this place), but he can’t because he just floats in the salt water. It seems like most of the members of the expedition temporarily forget about Teddy. Only Miss Bianca isn’t affected by this strange little town because she lives in a porcelain pagoda at home that her boy gave to her, so these buildings are very much like what she already knows.

Fortunately, the expedition gets some help from some friendly bats who live in the mines. The younger bats in the group say that they’ve seen little Teddy serving the governor of the salt mines, who tends to stay apart from most of the prisoners because the prisoners have attacked him before. This is fortunate news because it means that Teddy is closer to the little salt town than they thought, and it won’t be as difficult to find him as they anticipated. He’s on an island in the middle of the lake of salt water, and that’s not too difficult to reach because Bernard has already proven that it’s easy to float in salt water.
Once they find Teddy, they also have to get him onto a train to get him away from the salt mines, which may not be as easy.

My Reaction and Spoilers
I generally prefer the plots of the Disney movies to the original books in this series, but this was still a fun story. I was a little disappointed that they never actually used the two professors’ specialties. I thought at first that they would use the geology professor to spout some interesting and useful facts about caves or mines, but they didn’t, and there was nothing in the story where a mathematics professor would be particularly useful. It just seems like a missed opportunity there.
There were some funny moments in the story. I liked the part where one of the bats, not really seeing Bianca clearly because bats are near-sighted, comments to another that, whatever it, if it moves, you should salute it, and if it doesn’t, you should paint it. Bianca takes that as a sign that this particular bat has completed his National Service, also noting that being near-sighted isn’t a barrier for bat National Service because, if it was, no bat would be able to participate.
In a twist at the end of the story, it turns out that Teddy used to live with his uncle and that Teddy’s uncle is the tutor for the boy that Miss Bianca lives with. Once Teddy is restored to his uncle, he comes to the house with his tutor and becomes friends with Miss Bianca’s boy.
