A combination of long-slit, narrow-band imaging and IUE observations are used to establish the properties of the ionized gas in and around a sample of nineteen emission line radio galaxies (ELRGs). The extended emission line regions (EELRs), which proved to be a common feature of ELRGs are studied. The EELRs are shown to have a wide variety of forms and kinematics. It is suggested that this variety reflects a number of different origins for the gas. The spectra of the EELRs show a marked similarity to those of the active nuclei with lines from species as diverse as O(0), O(++), and He(+) present in individual spectra. Photoionization by a continuum with a significant X-ray component is the most likely ionization mechanism, but it is not yet clear that the ionizing photons originate in the active nuclei. Under the assumptions that the nuclear continuum is isotopic, time independent, and has a power-law form it is shown that in many galaxies there is no evidence for the continuum required to produce the great H luminosities in the extended clouds. Apart from data on the extended emission line regions, spectra of the nuclear region are also presented. The variations in the broad emission lines emitted by the nucleus of 3C382 are studied in detail.
