3.  Observe that the future perfect may be formed by adding ero\, the
  future of sum\, to the perfect stem.  But the third person plural ends
  in -erint, not in -erunt.  The tense sign is -eri-.

  4.  All active perfects, pluperfects, and future perfects are formed on
  the perfect stem and inflected in the same way.

188. DIALOGUE

THE BOYS TITUS, MARCUS, AND QUINTUS

First learn the special vocabulary, p. 289.

  M. Ubi fuistis, Tite et Quinte? 
  T. Ego in meo ludo fui et Quintus in suo ludo fuit.  Boni pueri fuimus. 
    Fuitne Sextus in vico hodie? 
  M. Fuit.  Nuper per agros proximos fluvio properabat.  Ibi is et
    Cornelius habent navigium. 
  T. Navigium dicis?  Alii[1] narra eam fabulam! 
  M. Vero (Yes, truly), pulchrum et novum navigium! 
  Q. Cuius pecunia[2] Sextus et Cornelius id navigium parant?  Quis iis
    pecuniam dat? 
  M. Amici Corneli multum habent aurum et puer pecunia non eget. 
  T. Quo pueri navigabunt?  Navigabuntne longe a terra? 
  M. Dubia sunt consilia eorum.  Sed hodie, credo, si ventus erit
    idoneus, ad maximam insulam navigabunt.  Iam antea ibi fuerunt. 
    Tum autem ventus erat perfidus et pueri magno in periculo erant. 
  Q. Aqua vento commota est inimica nautis semper, et saepe perfidus
    ventus navigia rapit, agit, deletque.  Ii pueri, si non fuerint
    maxime attenti, irata aqua et valido vento superabuntur et ita
    interficientur.
