Topographical map of the country lying between Thorold and Port Dalhousie shewing located line of enlarged Welland Canal
Bibliographic record
Abstract
Historic map showing a section of Niagara from Port Dalhousie to Thorold with north oriented toward the right. Text below the title reads: “Reduced from Plan of Surveys made in 1870-1”. Handwritten text below the scale, by the author, reads: "Thorold, 22 Aug. 1873. Thomas Monro." The map shows the Second and Third Welland Canals, beginning at the harbor in Port Dalhousie, travelling to Thorold. Also shown are main roads, creeks, ravines, concession and lot numbers. The Great Western Railway line runs from east to west and the Welland Railway from north to south. The Township of Grantham, St. Catharines, The Township of Stamford and the Township of Thorold are labelled. Handwritten markings in blue pencil are at multiple places along the canal. Handwritten on bottom right corner of map: “R 410 – Welland Canal – 1873 From Ms Div. Sept. 23/1960.” Stamp on verso: "Map Division, Aug 26 1969, Public Archives of Canada." And “New Welland Canal 440”. Handwritten on verso: 4/410 - New Welland Canal - 1873, Topo plan - C 93.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
