Working leaf · Undated01 / Water & weight

Before considering the value
of that cloth…

I would want its weight.

“One more” is not a unit of measurement. One more bolt of cloth, one more sack, one more person leaning across a rail: I would begin by finding out what was already aboard.

The difficulty is not merely whether a boat will float. It is whether that loaded boat can pass through the water available to it.

Lighter load: the waterline sits lower against the hull, with a smaller draft.lighter loadwaterlinedraftHeavier load: the same hull has a higher waterline and a greater draft.heavier loadwaterlinedraft
Concept sketch: the same hull at rest with different loads. Dashed lines mark the waterline relative to each hull. Not to scale; no measurements taken.

What I would need

  • Hull dimensions and form; weight of the boat.
  • People, cargo, and their distribution aboard.
  • Draft with that load; water depth along the difficult passage.
  • Measurements repeated while the water level changes.

A sketch for asking the question. Not a reconstruction of Broussard’s boat.

Questions to carry forward02 / Water & evidence

The line beneath the roots

The dark stripe is an observation within the telling. “Ebb tide” would be an explanation. I must not let the explanation slip into the observation simply because it fits neatly.

Where is this passage? What connects it to the river and to tidal water? What has the rain been doing? At what times were the water levels observed?

What survives the morning?

Flour. Cloth. Tools. Coffee. A useful reminder to look beyond the weapons. People needed to eat, mend things, earn money, and get home with something dry.

If a fragment of cargo were found, I would want its context before its adventure: its position, the deposit around it, the objects beside it, and any evidence that it had been moved.

A cloth fragment would not introduce itself as the proceeds of a particular raid. Nor would it tell me who had wanted it badly enough to consider overloading a boat.

Leave this question open

What might the ordinary things tell us about the people a dramatic account leaves at home?

No conclusion entered. Return to the context.

Marr Field Notes — Chapter One

Dr. Elspeth Marr | Water, weight, and the traces of everyday life

Before considering the value of that cloth, I would want its weight.

A boat floating at rest displaces water equal in weight to itself and everything it carries. Adding cargo makes it settle lower, increasing its draft—the depth of hull below the waterline. In a shallow passage, that leaves less clearance beneath the boat. Broussard’s extra bundle would therefore have affected more than the morning’s profit. I would want its weight and the boat’s dimensions before estimating how much.

The falling water also requires attention. Wetland water levels respond to rainfall, river flow, groundwater exchange and, where connected to tidal waters, the tide. The chapter does not establish the cause of this particular fall. An ebb tide is a possible explanation. I would still require a location and measurements before adopting it.

The flour, cloth, tools, and coffee interest me as much as the weapons. Material remains can help us investigate food, work, and exchange, but their context matters: where they were found, what accompanied them, and how they came to be there. I would not identify a particular raid—or its participants—from a cargo fragment alone. I would, however, want to know what else was found beside it.
