Until the 1970s, when you handed money to a sales assistant in Selfridges,
the assistant did not give you change. They could not. There was no till
at the counter. There was instead a small brass aperture on the wall
behind the counter, and the assistant rolled your banknotes and the
docket into a wooden or metal canister, screwed it into the tube, pulled
a handle, and your money flew off through the building's walls to a
centralised cash office somewhere out of sight, where a clerk processed
the transaction, signed the receipt, screwed the change back into the
canister, and fired it back. You waited at the counter. The whoosh of
returning canisters was a constant retail sound, and the tubes that
carried them were called Lamsons.
William Stickney Lamson, a Civil War veteran who ran a five-and-dime in
Lowell, Massachusetts, patented the first cash-carrier system in 1881.
The original was almost comically simple: hollow wooden balls rolling
along gently sloping wood-and-leather rails, propelled by gravity from
the sales counter to a cashier's loft above. He founded the Lamson Cash
Carrier Company in Boston the next year. By 1884 an Irish-American
agent, John Magrath Kelly, had set up the British arm in London and
secured the European, African, Australian and Middle Eastern rights to
the patents. By 1888 the Lamson Store Service Company Ltd was
capitalised at £85,000, the equivalent of nearly ten million today.
The technology evolved fast. Wire systems came next, suspended pulleys
that fired carriages between counter and office on tensioned cables.
Then, in 1899, Lamson absorbed an American rival, the Bostedo Package
and Cash Carrier Company, and renamed it the Lamson Pneumatic Tube
Company. That was the form the technology took for the next seven
decades. By 1911 there was a purpose-built factory at Hythe Road,
Willesden Junction, in northwest London, and the tubes were going into
Selfridges, Harrods, John Lewis, Whiteley's and the Army & Navy.
What is hauntological about Lamson is not the equipment, which is
well-documented and unambiguous. It is the spatial logic. The till did
not live where the sale happened. The till was a room. Money was a thing
in motion through walls. The cashier was an institution rather than a
piece of equipment, and the act of selling something to a customer
involved temporarily losing physical possession of their payment to a
separate department of the building. This required trust between
assistant and customer that has no modern analogue, the till being now
the thing that confirms the sale rather than the thing the sale waits
on. It also required an architecture. Every counter piped or wired to a
central node. Every store designed around the geometry of cash
movement. Walk into a flagship interwar department store with the
original Lamson layout in mind, and the floor plan suddenly makes sense
in a way it cannot if you assume the till has always been a box on a
shelf.
The British systems lasted longer than they should have. Lamson
Engineering Ltd, formed by merger in 1937, only ceased independent
operation in 1976, when it was acquired. By that point most stores had
moved to electronic point-of-sale terminals, but a number of
installations stayed running well into the post-war decades, sometimes
for cash, sometimes downgraded to internal mail. A few survive as
restored curiosities. The Up-to-Date Store at Coolamon, in
rural New South Wales, still has its original ball-and-rail system in
working order, the only such installation known anywhere.
There is a particular lesson here for anyone who has worked in modern
retail and assumes the till is a kind of natural fact, the place where
money meets transaction at the point of contact. It isn't. There was a
longer era when the building counted the money for itself, in a single
secret room, and you waited politely for the canister to come back.
