The Sprinkler Day
WATERER persist 6 · act 34 · react 40 · learn 129 · loop 4
LIT WATERER keeps a house only when its number leaves residue 4. Six houses are watered: they sum to 129. Thirty-four houses stay dry. All forty houses sum to 820. Day 4 is the only day with a full bucket in the census row.
AMBER The page calls residue 4 Thursday. That name is assigned, the way the novel's twelve parts in The Russian Messenger are assigned to 1866 and the book to 1867. The chalk roster is the Petersburg twin.
WALL Houses 1 through 40. The other residues belong to other days, and those days are dry on this sheet.
MODEL A block seen from above. Blue lots are on. Tan lots are off. The curve is a hose.
