Harald, As I indicated last month, we saw bees do a mix of waggle dances and round dances after walking down a tube that was attached to the hive entrance. The tube was 3 m long. Bees had great difficulty walking all that way. Dance behavior was erratic. What are your latest thoughts about work at Archbold in late December or early January? I have written to Morse about using the hut, but no reply yet. Classes begin here on about Jan. 18. Thank you for your letter and the check. Best wishes, Keith
