The Miller type feeder has the same outside dimensions as the Langstroth hive. It contains two feeding "trays" that can be filled with syrup. The bees can enter up the center crawl space and access both sides. Large amounts of feed can be given this way with no disturbance to the bees or the beekeeper as the wire mesh above the crawl space keeps the bees from exiting the hive through the feeder. The drawings assume 3/4" lumber.
