_247._ There are no rules for gender in the third declension that do not
present numerous exceptions.[1] The following rules, however, are of
great service, and should be thoroughly mastered:

1. /Masculine\ are nouns in -or, -o:s, -er, -es (gen. -itis).

_a._ /arbor\, _tree_, is feminine; and /iter\, _march_, is neuter.

2. /Feminine\ are nouns in -o:, -is, -x, and in -s preceded by
a consonant or by any long vowel but /o:\.

_a._ Masculine are /collis\ (_hill_), /lapis\, /me:nsis\ (_month_),
/o:rdo:\, /pe:s\, and nouns in -nis and -guis--as /ignis\,
/sanguis\ (_blood_)--and the four monosyllables

/de:ns\, _a tooth_; /mo:ns\, _a mountain_
/po:ns\, _a bridge_; /fo:ns\, _a fountain_

3. /Neuters\ are nouns in -e, -al, -ar, -n, -ur, -us, and
/caput\.

[Footnote 1: Review Sec. 60. Words denoting males are, of course,
masculine, and those denoting females, feminine.]

_248._ Give the gender of the following nouns and the rule by which it
is determined:

animal calamitas flumen lapis navis
avis caput ignis legio opus
caede:s eques i:nsigne mare salu:s
calcar fi:nis labor mi:les urbs

I. _The First Bridge over the Rhine._ Salus sociorum erat semper cara
Romanis. Olim Galli, amici Romanorum, multas iniurias ab Germanis qui
trans flumen Rhenum vivebant acceperant. Ubi legati ab iis ad Caesarem
imperatorem Romanum venerunt et auxilium postulaverunt, Romani magnis
itineribus ad hostium finis properaverunt. Mox ad ripas magni fluminis
venerunt. Imperator studebat copias suas trans fluvium ducere, sed nulla
via[2] poterat. Nullas navis habebat. Alta erat aqua. Imperator autem,
vir clarus, numquam adversa fortuna commotus, novum consilium cepit.
Iussit suos[3] in[4] lato flumine facere pontem. Numquam antea pons in
Rheno visus erat. Hostes ubi pontem quem Romani fecerant viderunt, summo
terrore commoti, sine mora fug
