L C & Sons landscaping construction tends lawns in Lincoln, Rhode Island, on ground where the Blackstone slides past the old mill villages and the granite ledge of Lincoln Woods shoulders up under the turf. The work is weekly and unglamorous and quietly exacting: the mower laid down in clean parallel bands, the trimmer following a stone wall the way a hand follows a railing, the edge cut so crisply along the walk that the lawn looks poured rather than grown. Come October, when the maples along Great Road let go all at once, the crew hauls the year's leaves off and leaves the yard breathing again. There is a particular satisfaction in the last pass — engines off, the smell of cut grass hanging in the valley air, a property that looks cared for from the street.
