Dig for a Treasure by Dean Marshall, 1949.

This is the second book in The Invisible Island series. It begins with the arrival of the Lennox family and their two children, Hugh and Barbie. The Lennox family has been staying with various relatives since the father got out of the army, but now, they’ve found a house to rent in the small town of Anchorage, Connecticut. The children are looking forward to having a yard to play in, and the mother wants to have a garden.

Unfortunately, when they arrive they are shocked to see that the house they were going to rent has been destroyed by fire. Their landlord, Mr. Prentice, is also on the scene, and he regretfully tells them that the fire just happened, although they don’t know the cause, and that there are no other houses in the area to rent. At first, they think that they will have to go back to staying with relatives, but Mrs. Lennox says firmly that they won’t. The family has had enough of staying with relatives, and they desperately need a place of their own. It’s summer, so her idea is that they can camp out on the property of the burned house for a few months while they look around for another place to rent. The children are excited about the idea of a camp-out. Mr. Prentice says that he wouldn’t have any problem with the family camping on the land, and he returns their rent deposit to them, saying that they can stay at his house that night and get some camping equipment the next day.

While Hugh and Barbie are exploring the area and looking for their cat, who ran off, they meet the children from the first book in the series. Hugh is about the age of David Guthrie, and Barbie is about the same age as Winkie Guthrie, the youngest of the children who play on the island they call “The Invisible Island.” Since the previous book in the series, they have finished their stone hut, and it has a grass and sod roof and four built-in beds for the four Guthrie children. Mr. Guthrie is an architect, and he helped the children build the house.

Hugh and Barbie admire the hut, and they say that they wish they had a stone house like that because it couldn’t catch fire. They explain to the other children what happened to the house that their family was going to rent, and they ask the children if they would consider renting the stone hut to their family until they can find another place to live. Mr. Lennox isn’t really happy about the idea of camping in tents because he lived out of tents when he was in the army.

At first, the Guthrie children and the Leigh children aren’t sure that they want to rent out their stone hut. They spend a lot of time there, and they’ve been trying to save up money to add improvements. The hut really belongs to the Guthries, who built it, but they want to add an extra room for the Leighs. However, after thinking it over, they realize that they can earn more money as rent from the Lennox family than they can by just doing chores, and while the Lennox family stays in the hut, they can camp out on other parts of their little island, like the woods that they call “Sherwood Forest.”

Since the little hut is just a one-room hut with no bathroom or other amenities, the children aren’t sure at first whether the Lennox adults would want to stay there or not. However, staying in a stone hut does sound better than in a tent, where they would also have no bathroom or amenities. Mr. Lennox is also intrigued by the pond, where he can go fishing. The children and the Lennox family talk things over with Mr. Prentice and the Guthrie children’s parents, and they all agree to renting the stone hut to the Lennox family.

The Lennox family still isn’t sure whether or not they’ll find another house for sale or rent in the area. They want to stay in the area because Mr. Lennox has a job nearby and Mrs. Lennox knows that some of her ancestors used to live in the area, although she doesn’t know much about them. However, Anchorage is a small town, and most of the houses already have people living in them. There is only one empty house in the area, but the owner has always refused to rent it or sell it. Mr. Prentice explains that the owner believes that there is a treasure in the house or nearby, a necklace that once belonged to a queen, and she’s been looking for it for years. Mr. Prentice doesn’t think that there really is a necklace or, if there once was, it’s probably long gone, but the owner insists that it exists and is still there, somewhere.

The children are fascinated, and they ask Mr. Prentice to tell them the story of the queen’s necklace. He says that during the time of Queen Elizabeth (Tudor), the ancestors of the Winthrop family who owned the house did something for Queen Elizabeth that caused her to reward them with a golden necklace that was passed down through the family for generations. When the Winthrops came to the colonies in America around 1650, they brought that necklace with them. However, when they came to this area and settled there, they had problems with the local Indians (Native Americans).

Mr. Prentice says that he can’t blame the American Indians for resenting strangers coming and taking over their lands and hunting grounds or for them trying to stand up for their rights, but the situation escalated with increasing violence. David Guthrie protests that American Indians scalped people and that, if he’d been there at the time, he’d “show them.” Mr. Prentice explains that was exactly the problem – everybody who was there at the time thought he’d “show them”, and that’s why the violence escalated. As for the scalping, Mr. Prentice says that white people committed their share of atrocities, too, and when David is older and learns more about it, he might not feel so proud of his side in this battle. (I thought that was an amazingly honest and self-aware interlude about European colonization and its effects on Native Americans for a book written in the late 1940s, when cowboy and western shows were becoming popular, and American Indians were mainly portrayed as violent enemies to be defeated. I was a little concerned at first when “Indians” entered the story, but I was relieved that the author took this attitude.)

Continuing with the local legend, Mr. Prentice explains that the colonists received warning one day that the local tribe was going to attack. In preparation for the attack, some families hid valuable items that they didn’t want stolen or destroyed in the coming battle. Some people buried valuables, and others hid their valuables in wells or caves. Presumably, the Winthrops hid their necklace, called the Queen’s Chain, during this time, but nobody really knows what happened to it. The colonists fled the area, and the American Indians burned the entire village to the ground. Every man-made structure was destroyed during this attack. Although people later returned to the area and rebuilt the town, it’s unknown what valuables they retrieved or when or if they ever retrieved them from their hiding places. Because all the buildings and some of the trees were burned, many landmarks were destroyed, so some people might not have found their hidden valuables again, even if they managed to return to look for them.

Mr. Prentice is related to the Winthrop family, and so is his cousin, Lizzie, who currently owns the rebuilt house known as the Winthrop house. Lizzie is firmly convinced that the Queen’s Chain is still there, somewhere. She thinks it was never hidden during the attack that destroyed the first house and was passed down through the family but hidden by a later generation, which is why she won’t sell or rent the house. Mr. Prentice, on the other hand, thinks that the necklace is lost forever. He thinks that either the necklace was hidden with other valuables that were never retrieved after the attack or that the family found the necklace and sold it to get money to rebuild the farm that was destroyed. Mrs. Prentice, on the other hand, sides with Lizzie, saying that nobody in the Winthrop family would have sold the necklace because it was part of a family trust.

The children are fascinated by the story, and they immediately begin thinking about searching for the necklace themselves. They talk to Miss Lizzie about the story Mr. Prentice told them and use some of the descriptions that she gives them of the old Winthrop property and the plants that once grew in their herb garden to see if they can pinpoint the exact location of the original house and the hiding place that the Winthrops might have used for their valuables. Even though everything manmade was destroyed in the attack, some plants have a way of coming back, and the remains of the old herb garden might still be there, even almost 300 years later.

The treasure hunt takes on greater importance when the Guthrie children learn that their family might not be able to buy the island from Mr. Prentice. Mr. Prentice is also the Guthrie family’s landlord, and the family has been saving up to buy their house from him. They had also hoped to be able to buy the island where the children have been spending so much time, but Mr. Prentice is reluctant to sell it. Lumber is valuable, and he’s thinking of cutting down the pine trees on the island to sell the wood. The children are horrified at the thought that their beloved “Sherwood Forest” might be cut down! Perhaps, if they can find the missing treasure, they can persuade Mr. Prentice to sell the land to them and Miss Lizzie to rent her house to the Lennox family.

My Reaction and Some Spoilers

There isn’t as much imaginary play as “castaways” in this book as their was in the first book in the series, but the theme still shows up in some ways. The kids still go camping on the island. They use tents when the Lennox family is living in their hut. The children’s search for treasure also offers plenty of outdoor adventure, and I really enjoyed the element of mystery in the story.

The children approach the treasure hunt from the assumption that the necklace is still hidden wherever the Winthrops hid their valuables. They do find that spot and recover some relics of the 17th century, but the necklace is not among them. Readers probably won’t guess exactly where the necklace has really been hidden, but there are a few clues to notice along the way. Mrs. Lennox says at the beginning that her ancestors were from this town, even though she doesn’t know much about them. I had guessed that they might have a connection to the Winthrops, especially when Miss Lizzie explains that the name of the girl who hid the family’s valuables before the attack was Elizabeth, and there are other Elizabeths in the family. Besides Miss Lizzie, Mrs. Lennox is called “Betty” when her husband addresses her by her first name, and Betty is another nickname for Elizabeth. When Barbie recognizes something that Miss Lizzie has as being like something her family owns, Miss Lizzie realizes that the Lennox family is related to her. By comparing what each of them has and what Miss Lizzie knows about their family, they figure out what really happened to the necklace. It not only solves the mystery of the necklace, but once Miss Lizzie realizes that the members of the Lennox family are relatives, she’s happy to have them living in the old Winthrop house.

The problem of what will happen to the children’s island and the trees on it is solved when the children win a bet with Mr. Prentice. In the first book, the children called their island “The Invisible Island” because it isn’t obvious at first that it really is an island, surrounded by water on all sides. So far, the children have kept the knowledge to themselves and their parents. When the children accidentally refer to the island in Mr. Prentice’s presence and realize that Mr. Prentice isn’t aware that it’s really an island, they start to explain. Mr. Prentice can’t believe that there’s actually an island on his land, and he says that he will give up ownership if they can prove that it’s really an island. The children easily demonstrate that it’s truly an island, showing him all of the waterways and bodies of water around it, and Mr. Prentice says that they’ve won. The Guthries end up with control of the island and the trees on it.
