Morning comes early to the low ground along Fish Brook, mist standing over the grass while the air is still cool enough to work in. Boxman Lawn Service mows Boxford in that window — deck set high through July, stripes run straight across yards that were hayfields not long ago. Trimming around granite posts and old apple trees takes longer than the mowing, and it is the part that shows. When the blower finally quiets, the line along the front walk is straight enough to draw with a rule and the clippings are gone. Spring and fall carry the heavier work: raking out, cutting the beds back in, taking the last leaves off ahead of frost.
