After that pause, he strode on again along the broad winding path through the Grove.  What grand beeches!  Adam delighted in a fine tree of all things; as the fisherman’s sight is keenest on the sea, so Adam’s perceptions were more at home with trees than with other objects.  He kept them in his memory, as a painter does, with all the flecks and knots in their bark, all the curves and angles of their boughs, and had often calculated the height and contents of a trunk to a nicety, as he stood looking at it.  No wonder that, not-withstanding his desire to get on, he could not help pausing to look at a curious large beech which he had seen standing before him at a turning in the road, and convince himself that it was not two trees wedded together, but only one.  For the rest of his life he remembered that moment when he was calmly examining the beech, as a man remembers his last glimpse of the home where his youth was passed, before the road turned, and he saw it no more.  The beech stood at the last turning before the Grove ended in an archway of boughs that let in the eastern light; and as Adam stepped away from the tree to continue his walk, his eyes fell on two figures about twenty yards before him.

He remained as motionless as a statue, and turned almost as pale.  The two figures were standing opposite to each other, with clasped hands about to part; and while they were bending to kiss, Gyp, who had been running among the brushwood, came out, caught sight of them, and gave a sharp bark.  They separated with a start—­one hurried through the gate out of the Grove, and the other, turning round, walked slowly, with a sort of saunter, towards Adam who still stood transfixed and pale, clutching tighter the stick with which he held the basket of tools over his shoulder, and looking at the approaching figure with eyes in which amazement was fast turning to fierceness.

Arthur Donnithorne looked flushed and excited; he had tried to make unpleasant feelings more bearable by drinking a little more wine than usual at dinner to-day, and was still enough under its flattering influence to think more lightly of this unwished-for rencontre with Adam than he would otherwise have done.  After all, Adam was the best person who could have happened to see him and Hetty together—­he was a sensible fellow, and would not babble about it to other people.  Arthur felt confident that he could laugh the thing off and explain it away.  And so he sauntered forward with elaborate carelessness—­his flushed face, his evening dress of fine cloth and fine linen, his hands half-thrust into his waistcoat pockets, all shone upon by the strange evening light which the light clouds had caught up even to the zenith, and were now shedding down between the topmost branches above him.

Adam was still motionless, looking at him as he came up.  He understood it all now—­the locket and everything else that had been doubtful to him:  a terrible scorching light showed him the hidden letters that changed the meaning of the past.  If he had moved a muscle, he must inevitably have sprung upon Arthur like a tiger; and in the conflicting emotions that filled those long moments, he had told himself that he would not give loose to passion, he would only speak the right thing.  He stood as if petrified by an unseen force, but the force was his own strong will.
