and preventing its further descent. They then filled up the 
space above, joining the comb which had become detached to 
that from which it had been separated, and they concluded 
their labours by removing the newly constructed comb below, 
thus proving that they had intended it to answer a merely tem- 
porary purpose. 
Similarly, Dr. Dzierzon, an experienced keeper of 
bees, and the observer who first discovered the fact of their 
parthenogenesis, makes the general remark, — 
The cleverness of the bees in repairing perfectly injuries to 
their cells and combs, in supporting on pillars pieces of their 
building accidentally knocked down by a hasty push, in fasten- 
ing them with rivets, and bringing everything again into proper 
unity, making hanging bridges, chains, and ladders, compels our 
astonishment. 
Lastly, as still further corroboration of such facts, I 
shall quote the following from Jesse’s 4 Gleanings : ’ 1 — 
Bees show great ingenuity in obviating the inconvenience 
they experience from the slipperiness of glass, and certainly 
beyond what we can conceive that mere instinct would enable 
them to do. I am in the habit of putting small glass globes on 
the top of my straw hives, for the purpose of having them filled 
with hone v ; and I have invariably found that before the bees 
commence the construction of combs, they place a great number 
of spots of wax at regular distances from each other, which 
serve as so many footstools on the slippery glass, each bee 
resting on one of these with its middle pair of legs, while the 
fore claws were hooked with the hind ones of the bee next above 
him; thus forming a ladder, by means of which the workers 
were enabled to reach the top, and begin to make their combs 
there. 
Herr Kleine, in his pamphlet on Italian Bees and Bee- 
keeping (Berlin, 1855), says that on substituting during 
the absence of the bees a hive filled with empty comb for 
their own hive, the returning bees exhibit the utmost 
perplexity. As the substituted hive stands in the exact 
spot previously occupied by their own hive, the return- 
ing b^es fly into it without observing the change. But 
finding only empty combs inside, 4 they stop, do not know
