to get the weather-gauge of a ship
to cover one's eyes
to keep one's hand over one's eyes
to clam up
to hold one's peace
to hold one's tongue
to keep a still tongue in one's head
to keep a tongue in one's head
to keep one's mouth shut
to shut one's mouth
to hold one's nose
to pitch both nostrils shut
to cover sy's eyes
to keep one's hand over sy's eyes
to close sy's eyes
to close sy's eyes as a last duty
