On the hill above Lewiston, where Thorncrag's oaks hold the last gold of an August evening, a well-kept lawn is a small act of order. Stones Landscaping, Inc. keeps the grass even and the borders clean along the walks and drives of the city and out the farm roads toward Greene. The work is steady and plain: mowing on a set rhythm, trimming what the mower can't reach, edging until the line between turf and pavement is a drawn one, and dark mulch laid around the beds. There is a real satisfaction in the stripe left across a wide yard at dusk, with the smell of cut grass drifting down toward the water. Autumn comes down all at once in this part of Maine, so the leaves get hauled off before the first hard frost pins them flat. Come the following May, the same yards wake up ready.
