HIGH SCHOOL PLANNING
FINE ENTERTAINMENT FOR
NIGHT OF FEBRUARY II

Flagstaff high school is planning to
stage three one-act comedies, some
dancing numbers and music on Febru-
ary 27 in the high school auditorium.
The plays are "a Proposal Under Diff
ficulties," a clever little farce featur-
ing all sorts of love trials; "The Flor
ist Shop" picturing couple united
through a bunch Of orchids, and
"Hyacinth Halvey," an Irish scene
portraying humorous situations.
Duet dances with both Mardi Gras
and Spanish atmosphere will take
place between the plays. The high
school Ukulele club is to entertain
with several numbers. More music
will be furnished by the Girls Glee
club and an instrument trio.
The program promises to be lively
affair and it is hoped that all of Flag
staff will keep this date open and en-
Joy the home talent furnished by the
local high school.

By means OF the variable resist

slant Of the circuit can be reduced
to any value necessary to sustain
regeneration without %squealing, or

Another advantage of the tapped
