Jail tree

Jail tree is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Jail tree rather than just read about it. In short: A jail tree is any tree used to incarcerate a person, usually by chaining the prisoner up to the tree. Jail trees were used on the American frontier in the Territory of Arizona, in the late 19th and early 20th centuries; jail trees were also used in Australia.

Key takeaways

Jail tree belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Jail tree to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Jail tree from memory before moving on to harder problems.

Reference excerpt

A jail tree is any tree used to incarcerate a person, usually by chaining the prisoner up to the tree. Jail trees were used on the American frontier in the Territory of Arizona, in the late 19th and early 20th centuries; jail trees were also used in Australia. Few jail trees survive to this day.

Examples Gleeson Jail Tree: A large oak tree in the ghost town of Gleeson, near Tombstone, Arizona. A thick metal cable and chain wrapped around the trunk of the tree was used with handcuffs to chain up prisoners. In use before the construction of the original wooden-frame jail building in 1909. Paradise Jail Tree: Pair of oak trees with a log chain stretched between them. Prisoners were shackled to the chain. Located in the ghost town of Paradise, Arizona. Ruby Jail Tree: Mesquite trees in the ghost town of Ruby, Arizona, used for chaining up prisoners sometime before the construction of the current concrete jail building in 1936. Wickenburg Jail Tree: 200-year-old mesquite tree with a chain and handcuffs for prisoners. Located in Wickenburg, Arizona, and in use between 1863 and 1890. Preserved for its historical association with the early-day Wickenburg mining camp. Wyndham Boab Prison Tree: A large boab tree south of Wyndham, Western Australia that was used as a lockup for Aboriginal prisoners on the way to the town during the late 1890s. Unlike other jail trees, prisoners were held inside the boab's hollow trunk, though prisoners were also chained to the tree outside if there was no room inside. A similar tree in Derby was also thought to be used for the same purpose but there is no evidence to support its use as such.

Similar jails

Arivaca Jail: A slab of concrete in the ground with two metal bars embedded in the center, where heavy log chains for the prisoners were attached. Located in the historic town of Arivaca, Arizona. Greaterville Jail: A large hole in the ground. A rope was used for letting prisoners up or down. Located in the ghost town of Greaterville, Arizona. Tubac Jail: Wooden post in the ground with an attached pair of leg irons to hold the prisoner. The leg irons were originally used on board a Spanish ship to chain prisoners to the mast before being used as the town jail in Tubac, Arizona. They are now on display in the museum of the Tubac Presidio State Historic Park.

Worked examples

Example 1 — a first encounter with Jail tree

Start with the simplest possible case. Write down what Jail tree claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Jail tree before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Jail tree ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Jail tree

In research: Jail tree appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Jail tree in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Jail tree is common in secondary-school and first-year university syllabi. It links to neighbouring topics American frontier, Arizona Territory, History of Arizona, so understanding it makes those chapters shorter.
In everyday life: Look for Jail tree outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
