QUESTIONS OF TENSE.[80]--The tense of a verb should correctly express
the time referred to. Most errors in the use of tenses are violations of
some one of the following principles, which are established by good
usage:--

1. Principal verbs referring to the same time should be in the same tense.
2. The _perfect indicative_ represents something as now completed--as
begun in the past but continuing till the present, at least in its
consequences: as, "I _have lost_ my book" (so that now I do not have
it); "This house _has stood_ for ninety years" (it is still standing);
"Bishop Brooks _has died,_ but he _has left_ us his example" (he is not
now among us, but we have his example).
3. The tense of the verb in a dependent clause varies with the tense of
the principal verb:[81] as,
I _know_ he _will_ come.
I _knew_ he _would_ come.
I _have taken_ the first train, that I _may_ arrive early.
I _had taken_ the first train, that I _might_ arrive early.
Blanche _will be_ frightened if she _sees_ the bat.
Blanche _would be_ frightened if she _saw_ the bat.
Blanche _would have been_ frightened if she _had seen_ the bat.
Present facts and unchangeable truths, however, should be expressed in
the present tense, regardless of
