Home and Garden

It is only possible to view all six watering cans from three of the five windows. Furthermore it is only possible (visible) to follow a line along fourteen box hedges (the first seven being in their youth), to arrive six watering cans, from just one of these three windows. And there is a window (not one of the said three) that can only see five of the mature box hedges and nothing of the youthful hedges, or for that matter a single watering can.
