herds of bison, and sometimes killed from 100 to 200 at one time; but it
was to make sure of having enough meat and hides, and because he
expected to use the product. I think that even the worst enemies of the
plains Indians hardly will accuse them of killing large numbers of
bison, elk or deer merely for the pleasure of seeing them fall, or
taking only their teeth.

It has remained for the wolf, the sheep-killing dog and civilized man to
make records of wanton slaughter which puts them in a class together,
and quite apart from other predatory animals. When a man can kill bison
for their tongues alone, bull elk for their "tusks" alone, and shoot a
whole colony of hippopotami,--actually damming a river with their
bloated and putrid carcasses, all untouched by the knife,--the men who
do such things must be classed with the cruel wolf and the criminal dog.

It is now desirable that we should pause in our career of destruction
long enough to look back upon what we have recently accomplished in the
total extinction of species, and also note what we have blocked out for
the immediate future. Here let us erect a monument to the dead species
of our own times.

It is to be doubted whether, up to this hour, any man has made a list of
the species of North American birds that have become extinct during the
past sixty years. The specialists have no time to spare from their
compound differential microscopes, and the bird-killers are too busy
