   We propose to study a sample of the smallest Galactic supernova
   remnants from the MOST radio catalog. The sample includes both
   plerionic and shell-like SNRs that are likely to be heavily absorbed by
   the interstellar medium. The goal of the proposal is to find and study
   new examples of pulsar-powered synchrotron nebulae and young ejecta-
   dominated remnants. This proposal relies on the high energy imaging and
   spectroscopic capabilities of ASCA that allow us to observe at energies
   above 4 keV where the effects of ISM absorption are not important.
