This decrease in their numbers is attributable to many causes:―

1st. From infanticide, to a limited extent.

2nd. From certain rites performed upon young men of some tribes,

impairing their physical powers.

3rd. From the introduction among them by Europeans of a more aggravated

form of syphilis than was known to exist previous to our occupation of

the country. {63}

4th. From the introduction and use of intoxicating liquors, a habit of

using which to excess is prevalent among the natives, who, despite of

existing laws to the contrary, are frequently aided by Europeans in

obtaining supplies.

5th. From the promiscuous intercourse of the sexes. This is proved by

evidence to be carried to such an extent, not only between themselves,

but also with Europeans, as, in a great measure, of itself to account

for the infecundity of the race.

6th. From the disproportion of sexes.
