260 ANIMAL INTELLIGENCE 
In another case it is not distinctly taken into the 
mouth and expelled, but is simply picked up and at 
once dropped. 
Water is presented to the chicks. They peck at 
some drops on the side of the tin containing the water. 
They accidentally get the beak into the water, when 
drinking follows. 
They do not spontaneously put in the beak and drink, 
either before this accidental result or after, and in this 
matter they all three behave alike. 
They are seen to scratch the head with a foot. 
At this age another lot of six, which are with a 
different mother, do drink on invitation (clucking) of 
the mother. 
They also eat rather better on her invitation than 
without it. 
They run to the mother from a distance of 4 feet. 
Five hours later—The mother hen drinks, whereupon 
two of the chicks run rapidly from a distance of 6 
inches and drink. 
One of them wipes its beak on the ground. 
The hen is later in a box, and cannot be seen by the 
chicks, yet they move towards her, z.e. in the direction 
of the sound she makes. 
3rd day, 2 p.M.—They have been fed a couple of times 
before to-day. 
They are now given very small pieces of meat, with 
which they run off, peck it against the ground, and make 
off from each other, as does a mature hen. One even 
escapes through wire-netting into the next “run.” They 
are now out of doors in suitable “runs.” 
One is seen to swallow a piece too large with no more 
difficulty than a mature bird apparently. 
One of the chicks begins to eat lettuce, on which the 
mother hen is feeding.
