Did the Kessler Mill Fire Cause a Strike?
A seventh-grade class investigates the question: Did the 1911 fire at the Kessler Mill cause a strike? The available evidence:
- (a) A newspaper article the day after the fire: no injuries; work resumes Monday.
- (b) A worker's diary, three weeks later: the looms stand idle; we ask for pay while the roof is fixed.
- (c) A company ledger showing March 1911 wages at 40% of February's total.
- (d) A photograph labeled strikers at the mill gate, with no date.
- (e) A 1975 interview with a woman who was 9 years old in 1911: my father was out of work that spring.
- (f) A county history published in 1920: labor unrest followed the fire.
The teacher requires every claim to name the source that supports it and forbids the phrase this proves.
1. Evaluate each item for this specific question: what can each one actually establish? Rank them from strongest to weakest and justify the ranking.

Strongest is (c), the ledger: a routine record made before any dispute, measuring pay directly. It establishes lost wages - not a strike.
Next, (b), the diary: firsthand and close in time, but one person's view, and we ask is vague about who asked and of whom.
Then (a), the newspaper: close in time, but written to report the fire, and work resumes Monday may repeat the owner's hope rather than a fact; it speaks to the fire, not to March.
Then (e), the 1975 interview: 64 years later, but a child's memory of a father being out of work is plausible; strong for family experience, weak for dates and causes.
Then (f), the county history: secondary, nine years later, and labor unrest is a vague phrase useful only as a lead.
Weakest is (d), the undated photo: it cannot be tied to 1911 or to this mill, and a caption may have been added later.
2. State the strongest finding the class can defend in one sentence, and one claim it cannot yet make. Explain the gap.

Defensible: After the 1911 fire, the mill paid workers far less, and at least one worker reported idle looms and a demand for pay while the roof was repaired - evidence of a serious work disruption.
Not yet defensible: a strike occurred, or the fire caused a strike. A strike is organized action with stated demands and a target, and only one diary hints at demands. The ledger's 40% figure fits a layoff, a strike, or a slow restart equally well, so it cannot choose among them.
The gap is twofold. Definitional: a stoppage is not a strike, and careless wording would upgrade the evidence. Numerical: one worker and an unknown total cannot establish how many people acted or whether they acted together. Causation also needs sequence - fire, then disruption - and item (a) suggests work was expected to resume, which cuts against an immediate walkout.
3. What single new source would most reduce the uncertainty, and what would make the class change its conclusion? Address the risk of filling gaps with the county history.

Best single source: the local newspaper's issues for the weeks after the fire - a report of a workers' meeting, a list of demands, a notice that hands were wanted or not wanted. It would show whether organized action was reported, with names and numbers, and it is independent of the company. A payroll or employment roster for April to June 1911 is a close second, though company records gave the company an interest in calling a strike a layoff.
What would change the conclusion: a report of a meeting where workers voted on demands and the mill responded - that would establish organization, not just disruption. Conversely, near-full pay in April would undercut the idle-looms claim and point to a quick repair.
The county history is the source most likely to repeat local rumour, so it should be used only to generate search terms. Where evidence is missing, the class should say so plainly rather than borrowing a phrase from a secondary source to fill the gap.
