Then he retreated a few steps further on seeing Silvere clench his fists.
And as Silvere, pale and trembling more than she, began to clench his fists: "Stop!"
She made an impatient movement and he saw her clench the hand that was lying on the table.
She had to clench her teeth to keep her lips from trembling.
His hands, busily engaged in buttoning his gloves, did not clench.
Then he tried to clench his fist in them without tearing them.
Here his face darkened, and his fists could be seen to clench with much meaning.
His face, naturally so frank, seemed to clench up, as if he were riding at a fence.
He loosed the clench of his hands about his knees and jumped to his feet.
If he should clench his fist it is supposed to be a sign that his party will resist to the last.
