The oil pattern

Twenty-two milliliters, more or less, laid down across forty feet of lane in under ninety seconds by a machine that leaves no visible trace once it retracts. The pattern is not a coating; it is architecture, a series of overlapping passes applied in varying lengths per board, heavier near the center where most bowlers send the ball and lighter toward the gutters where mercy is not required. House patterns run wide and forgiving, built to let error survive. Sport patterns narrow the margin to a width some players describe, with visible resentment, as theoretical. Nobody in the building can see any of it. The oil has no color, no texture underfoot, no smell beyond a faint mineral note if a hand is pressed flat to the boards, which almost never happens because nobody expects there to be anything there to feel. It is known only by its aftermath: a ball that hooks predictably on lane three and skids straight on lane four, both oiled from the same reservoir an hour apart. By the ninth or tenth frame the pattern has begun to migrate, carried down the boards by the balls themselves, and the machine will not run again until the last league has gone home for the night.
