Gratifyingly, the bees are all there - not that I counted them or called them by name - and the colony seems none the worse for the move.
I did notice that in my haste I had not put the outer lifts (the boards that give the WBC hive its pleasing traditional ziggurat appearance) on properly last time. Apart from a little shimmying around, the next step is to start clearing the bees with the boards and bee escapes.
Small admission: that's what I meant to do today, and forgot.
http://en.wikipedia.org/wiki/Ziggurat: "A ziggurat (Akkadian ziqqurrat, D-stem of zaqāru "to build on a raised area") is a temple tower of the ancient Mesopotamian valley and Iran, having the form of a terraced pyramid of successively receding stories." Nothing like a WBC hive, then.
