SAGACITY OF BEES. 
ARE NOT BEES DIRECTED ALONE BY INSTINCT ? 
On this subject I have but little to say, as I have 
failed to discover anything uncommonly remarkable, 
separate and distinct in one swarm, that another 
would not exhibit. I have found one swarm guided 
alone by instinct, doing just what another would un-

of instinct, with their love of the marvellous, must add 
a good share of reason to their other faculties, — “ an

and comparing the results of different swarms in sim- 
ilar cases, one might arrive at such conclusion. It is 
difficult, as all will admit, “ to tell where instinct ends, 
and reason begins.” Instances of sagacity, like the 
following, have been mentioned. “ When the weather 
is warm, and the heat inside is somewhat oppressive, a 
number of bees may be seen stationed around the en-

against the glass side. The bees, unable to penetrate
