--_Byron_.

For as yellow gold is tried by fire, so do moments of adversity prove
the strength of friendship. While fortune is friendly and smiles with
serene countenance, crowds surround the rich; but when heaven's thunder
rolls, they vanish, nor has he one who knows him, though lately
encircled by troops of boon companions.

--_Ovid_.

Our best friends have a tincture of jealousy even in their friendship;
and when they hear us praised by others, will ascribe it to sinister and
interested motives if they can.

--_C. C. Colton_.

For to have the same predilections and the same aversions, that and that
alone is the surest bond of friendship.

--_Sallust_.

False friends, like insects in a summer's day,
Bask in the sunshine, but avoid the shower;
Uncertain visitants, they flee away
E'en when misfortune's cloud begins to lower.
Into life's bitter cup true friendship drops
Balsamic sweets to overpower the gall;
