 The year 1929 was special in other ways, too.It was the first time that Christmas tree decorations (not just lights) were placed on the tree.To prevent the tree from being damaged during decoration, scaffolding was erected around the tree (instead of ladders placed into the branches), lighter strings of lights were used, lights with a lower wattage were employed, and a low fence erected around the tree so that its roots would not be trampled.
