At 5.80 P. M., called them out again. Out of six, five were 
marked ones. 
October 8th. Called them out at 7.15. Six came out, all marked 
ones. 
October 9th. Called them out at 6.40. Out of the firs@ten, 
eight were marked ones. . 
Called them out at 11.30 A.M. Out of six, three were marked. 
I marked the other three. 
Called them out at 1.30 P. M. Out of ten, six were marked. 
Called them out at 4.30. Out of ten, seven were marked. 
October 10th. Called them out at 6.05 A. M. Out of six, five 
were marked. 
Shortly afterwards I did the same again, when out of eleven, 
seven were marked ones. 
At 5.30 P. M., called them out again. Out of seven, five 
were marked. 
October 11th. At 6.30 A. M., called them out again, Out of 
nine, seven were marked. 
At five P. M., called them out again. Out of seven, five were 
marked, 
After this day they took hardly any notice of the scents. 
Thus in these nine experiments, out of the ninety-seven bees 
which came out first, no less than seventy-one were marked ones, 
though out of the whole number of bees in the hive there were 
only twelve marked for this purpose, and, indeed, even fewer in 
the earlier experiments. I ought, however, to add that I gener- 
ally fed the bees when I called them out. 
It is sometimes said that the bees of one hive all know one 
another, and immediately recognize and attack any ina om 
another hive. At first sight this certainly implies a great dea ti 
intelligence. It is, however, possible that the bees of „particu A 
ives have a particular smell. Thus Langstroth, in his nerza 
ing treatise on the Honey Bee, says, ‘‘ Members of iets co 
onies appear to recognize their hive companions by tk e sense 
smell ;”” and I believe that if colonies are sprinkled with =i 
syrup, they may generally be safely mixed. Moreover, z ; ar X 
turning to its own hive with a load of treasure is a very di ni k 
creature from a hungry marauder ; and it is said that a bee, i 
laden with honey, is allowed to enter any hive with impunity. 
Mr. Langstroth continues, “ There is an air of roguery about a 
thieving bee which, to the expert, is as characteristic as are the 
motions of a pickpocket to a skillful policeman. Its sneaking
