At last they were across the Drive and safe on the lower walk of the park. "Here's my old bench." Catherine sat down with her mother. "I can see clear to those steps from here." Spencer was off with a whoop, his figure balancing surely as he sped. Marian chased him, a determined erectness in her body. Letty paddled after them, chanting loudly to her duck. "When school opens," Catherine sighed, "they'll have some exercise, poor chickens. City life isn't easy for them." "It's no place for children." Mrs. Spencer watched a passing group, a beruffled little girl yanking fretfully at the hand of her nurse, a small, fat boy howling in tearless monotony. "Not even a yard." "We talked about a suburb last year. But Charles hates the idea of commuting, and he is so busy with his additional work that he'd never be home at all." "Won't you miss these little expeditions with your children?" Catherine looked hastily at her mother. But the bright blue eyes were apparently intent on a tug steaming along the river. The tide was running swiftly down, swirling off into the quiet water near shore bits of refuse, boxes, sticks, which caught the sun in dazzling sham before they drifted into ugly lack of movement. "They don't need me when they are playing here," said Catherine. "Anyone would do, just to watch them." "I wonder," said her mother. "I see some of these nurses do outlandish things." "Miss Kelly looks intelligent and kind." Again stubbornness in Catherine's mouth, in her lowered eyelids. "And I might as well admit, I'm reaching the place where I won't be either of those things. You'd be ashamed of your daughter if you knew how peevish she can get!" "Catherine, dear"--Mrs. Spencer laid her hand softly on Catherine's--"you know I don't mean to interfere. But are you sure you haven't just caught the general unrest, in the air and everywhere?" "Where did it come from?" The children were coasting toward them, down the little hill. "Why do I feel it?" "Oh, the war, no doubt." "The war! Blame that for my hatred of this dreadful monotony, my lack of self-respect, my--my grubby, dingy, hopeless feeling!" "I can see you have your mind made up." Mrs. Spencer caught Marian as she tumbled, laughing, against the seat. "I beat Spencer back!" "Come on and I'll beat up the hill!" Spencer wiggled to a standstill. A wail went up. Letty and her duck were upside down, a jumble of legs and red wheels. Spencer clattered away to rescue her, Marian after him.
