The authors present several observations of the 22.2 GHz H2O maser line from two C stars, V778 Cyg and EU And, and the 1665/67 MHz OH maser lines from V778 Cyg. For both sources the intensity of the H2O line has varied by more than a factor of 5 over several months. The authors interpret the systems as being binaries, each with an M star component with a thick shell and a C star component.
