ANIMAL INTELLIGENCE. 
than yield, it will allow itself to be beaten to pieces with a stick. 
If it seizes a man’s hand, it must be killed before it will quit its 
hold. The magnitude of the horse terrifies it as little as the 
address of the dog, which last is fond of hunting it. When a 
harvester perceives a dog at a distance, it begins by emptying 
its cheek-pouches, if they happen to be filled with grain ; it then 
blows them up so prodigiously, that the size of the head and 
neck greatly exceeds that of the rest of the body. It rears itself 
upon its hind legs, and thus darts upon the enemy. If it catches 
hold, it never quits it but with the loss of its life ; but the dog 
generally seizes it behind, and strangles it. This ferocious dis- 
position prevents it from being at peace with any animal what- 
ever. It even makes war against its own species. When two 
harvesters meet, they never fail to attack each other, and the 
stronger always devours the weaker. A combat between a 
male and a female commonly lasts longer than between two 
males. They begin by pursuing and biting each other, then 
each of them retires aside, as if to take breath. After a short 
interval they renew the combat, and continue to fight till one of 
them falls. The vanquished uniformly serves as a repast to the 
conqueror. 
If we contrast the fearless disposition of the harvester 
with the timidity of the hare or rabbit, we observe that in 
respect of emotions, no less than in that of intelligence, 
the order Rodentia comprises the utmost extremes. 
The so-called 6 prairie-dog 5 is a kind of small rodent, 
which makes burrows in the ground, and a slight eleva- 
tion above it. The animals being social in their habits, 
their warrens are called 6 dog-towns. 5 Prof. Jillson, Ph.D., 
kept a pair in confinement (see 6 American Naturalist, 5 
vol. v., pp. 24-29), and found them to be intelligent and 
highly affectionate animals. These burrows he found to 
contain a 4 granary, 5 or chambers set apart for the reception 
of stored food. With regard to the association said to 
exist between this animal and the owl and rattle-snake, 
Prof. Jillson says, 6 1 have seen many dog-towns, with 
owls and dogs standing on contiguous, and in some cases 
on the same mound, but never saw a snake in the vicinity.’ 
The popular notion that the owl acts the part of sentry to 
the dog requires, to say the least, confirmation.
