seeing. Every first-rate museum must still employ competent
collectors; but I think that a museum could now confer most lasting
benefit, and could do work of most permanent good, by sending out into
the immense wildernesses, where wild nature is at her best, trained
observers with the gift of recording what they have observed. Such men
should be collectors, for collecting is still necessary; but they
should also, and indeed primarily, be able themselves to see, and to
set vividly before the eyes of others, the full life-histories of the
creatures that dwell in the waste spaces of the world.

At this point both Cherrie and Miller collected a number of mammals
and birds which they had not previously obtained; whether any were new
to science could only be determined after the specimens reached the
American Museum. While making the round of his small mammal traps one
morning, Miller encountered an army of the formidable foraging ants.
The species was a large black one, moving with a well-extended front.
These ants, sometimes called army-ants, like the driver-ants of
Africa, move in big bodies and destroy or make prey of every living
thing that is unable or unwilling to get out of their path in time.
They run fast, and everything runs away from their advance. Insects
form their chief prey; and the most dangerous and aggressive lower-
life creatures make astonishingly little resistance to them. Miller's
attention was first attracted to this army of ants by noticing a big
centipede, nine or ten inches long, trying to flee before them. A
number of ants were biting it, and it writhed at each bite, but did
not try to use its long curved jaws against its assailants. On other
occasions he saw big scorpions and big hairy spiders trying to escape
in the same way, and showing the same helpless inability to injure
their ravenous foes, or to defend themselves. The ants climb trees to
a great height, much higher than most birds' nests, and at once kill
