[Sidenote: Causes.]

Divorce from the bonds of matrimony may be decreed against the husband
for the following causes:

1. When he has committed adultery subsequent to the marriage;

2. When he wilfully deserts his wife and absents himself without a
reasonable cause for the space of two years;

3. When he is convicted of felony after the marriage;

4. When, after marriage, he becomes addicted to habitual drunkenness;

5. When he is guilty of such inhuman treatment as to endanger the life
of his wife. [§3414.]

A previous law of our state provided that when it was fully apparent to
the court that the parties could not live in peace and happiness
together, and that their welfare required a separation, a decree of
divorce might be granted, but no valid divorce can now be granted for
any other cause than for some one of those enumerated above; and this is
true, although it may plainly appear that a party has wholly disregarded
his marriage vows and obligations in various other ways.

[Adultery.]

As the direct fact of adultery can seldom be proved, when a divorce is
asked on this ground, it will be sufficient if the fact can be shown by
circumstances which would be inconsistent with any rational theory of
