Six Seconds on the Stairs

Ellis Island, 17 April 1907 — the day 11,747 people met a doctor whose examination was already over before they knew it had begun.
You are on the stairs to the Registry Room. Six doctors are already looking at you.

The most important medical exam of your life will last six seconds. You will not be told when it starts. It has already started. You are climbing the stairs.

Act I · The Line — six seconds, six things

Two Public Health Service doctors stood at the top of the stairs. As you climbed with your bundle, they read six things off you in one look: scalp, face, neck, hands, gait, general condition. If something caught their eye, they reached out and drew a letter on your right shoulder in blue chalk. You never saw them do it.

Doctors watch from the top step. You have six seconds to look healthy.

The chalk alphabet

Documented from the U.S. Public Health Service manual, 1917. Fifteen to twenty percent of arrivals were marked. Most marks meant "step aside for a second look" — not "sent back."

Act II · The Buttonhook

If the second doctor's eye caught yours, he took a small brass buttonhook — the tool you used at home to fasten dress-shoes — and flipped your upper eyelid inside-out. He was looking for trachoma, a bacterial eye infection that can end in blindness. A single "CT" in chalk was almost always a ticket home.

Two seconds. No gloves. President Roosevelt objected in 1906; the practice continued.
Look and decide: healthy, or trachoma?
Passengers seen: 0
Missed cases: 0
Wrongly marked CT: 0
In 1907, about half of all medical exclusions were for trachoma. A wrong call sent a healthy person back across the ocean.

Act III · The 29 Questions

You now walk into a hall the size of a train station. A registry clerk holds the ship's manifest — 29 columns already filled in for you weeks ago in the port of embarkation. He asks the questions again. Your answers must match. If they do not, you go to a bench marked SI — Special Inquiry.

Question: 1 / 29
Matches with manifest: 0
Mismatches: 0
The clerk waits.
Real 1907-era manifest questions — the "List of Aliens" required by the Immigration Act of 1907. Legend says immigrants had their names changed here; historians disagree — the manifest was written in the port they LEFT.

Act IV · The Cube Test

If the clerk was not sure of you — you looked tired, or you did not understand his English, or the doctor had written X on your shoulder — you were sent to Dr Howard Knox. He set four wooden cubes on a table, tapped a pattern, and asked you to copy it. He believed a test without language could measure a mind. Historians now agree the tests measured something else: how frightened you were, and how much your world resembled his.

Knox Cube Imitation Test, first used at Ellis Island in 1913. Cubes: 1, 2, 3, 4 — left to right.
Press "Watch" to see the doctor's pattern, then tap the same cubes in the same order.
Round: 0
Copied correctly: 0
Knox himself later wrote that his tests should not be used to bar immigrants alone. They were, for years.

Act V · "Likely to become a public charge"

The Immigration Act of 1907 gave inspectors a phrase so elastic that it did the work of a wall: likely to become a public charge, or LPC. It was decided by a single officer in under a minute. Set the dials below to see what happened to a boatload of 1,000 arrivals — and which levers actually moved the number sent home.

Each dot is one arrival. Green = admitted. Amber = Special Inquiry. Red = deported.
Admitted: — / 1000
Held for Special Inquiry: —
Deported: —
Set the dials and land the ship.
Historically, roughly 2% of Ellis Island arrivals were sent back. That is small compared with the rejection rate at Angel Island (San Francisco), where Chinese immigrants faced weeks of interrogation under the Chinese Exclusion Act.

Act VI · Where they came from, where they went

In 1907 alone, 1,004,756 people passed through Ellis Island. Most had never been more than a day's walk from home. Click a country to see the top American cities their manifest listed as final destination.
