ANIMAL INTELLIGENCE. 
winter, cease to lay up honey. In contradiction to this 
statement, however, Kirby and Spence say, 4 It is known 
to every naturalist acquainted with the fact, that many 
different species of bees store up honey in the hottest 
climates, and that there is no authentic instance on record 
of the hive-bees altering in any age or climate their 
peculiar operations. 5 
On the other hand, more recent observation has shown 
that Dr. Darwin’s statement is probably correct. For, 
according to a note in Nature ,* European bees, when trans- 
ported to Australia, retain their industrious habits only 
for the first two or three years. After that time they 
gradually cease to collect honey till they become wholly 
idle. In a subsequent number of the same periodical 
(p. 411) a correspondent writes that the same fact is 
observable with bees transported to California, but is 
obviated by abstracting honey as the bees collect it. 
There seems to be no doubt that bees and wasps are 
able to distinguish between persons, and even to recog- 
nise those whom they are accustomed to see, and tp 
regard as friends. Bee-masters who attend much to their 
bees, so as to give the insects a good chance of knowing 
them, are generally of the opinion that the insects do 
know them, as shown by the comparatively sparing use of 
their stings. Again, many instances might be quoted, 
such as that given by Guerinzius, 1 2 wdio allowed a species 
of wasp native to Natal to build in the doorposts of his 
house, and who observed that although he often interfered 
with the nest, he was only once stung, and this by a 
young wasp ; while no Caffre could venture to approach 
the door, much less to pass through it. 3 This power of 
distinguishing between persons indicates a higher order 
of intelligence than we might have expected to meet 
with among insects ; and, according to Bingley, bees will 
not only learn to distinguish persons, but even lend them- 
selves to tuition by those whom they know. For he says,
