Stand above Baker's Falls in February and the whole river goes white and loud below the ledge, the hemlocks stiff with ice on the far bank. Winter is honest weather for tree work — the leaves are down, the structure of a maple is plain to read, and Tree Brothers Tree Service Inc. can take out what's dead or crossing and leave a better tree standing. Across the rest of the year the work runs to trimming, pruning and removals, keeping the yard trees of Kingsbury and Hudson Falls sound and shapely over the houses they shade. A big old tree is the slowest thing anyone owns, and caring for one is a long favor to whoever lives here next. That's the pride in it, and it outlasts any single season.
