Life had been so arduous for all of them from the start that she could not help dreading any sudden relaxation of his grasp upon what he held, though, as she knew from inspection of her own life, such sudden impulse to let go and make away from the discipline and the drudgery was sometimes almost irresistible.

But with Ralph, if he broke away, she knew that it would be only to put himself under harsher constraint; she figured him toiling through sandy deserts under a tropical sun to find the source of some river or the haunt of some fly; she figured him living by the labor of his hands in some city slum, the victim of one of those terrible theories of right and wrong which were current at the time; she figured him prisoner for life in the house of a woman who had seduced him by her misfortunes.

Half proudly, and wholly anxiously, she framed such thoughts, as they sat, late at night, talking together over the gas-stove in Ralph's bedroom.
