Leah could not cope with their two rigid little bodies, and, through welling tears of weariness and exasperation, she looked blankly up and down the dingy street for succour. If only her ally, Mr. Brennan, the policeman on the beat, would come! But Mr. Brennan was guarding a Grand Street crossing until such time as the last straggling child should have safely passed the dangers of the horse-cars, and nothing came in answer to Leah's prayer but a push-cart laden with figs and dates and propelled by a tall man, long-coated and fur-capped. His first glance read the tableau, and in an instant he grasped Percival, shook him into animation, threw him through the big door, and turned to reason with Algernon. But that rebel had already seen the error of his ways and was meekly ascending the steps and waving a resigned adieu to his sister. The heavy door clanged. Leah raised grateful eyes to her knight, and the thing was done. For the rest of that day Aaron Kastrinsky sold dates and figs at a reckless discount and dreamed of the fair oval of a girl's face framed in a shawl no more scarlet than her lips, while Leah's heart sang of a youth in a fur cap and a long coat who had been able to "boss them awful boys." Daily thereafter did Aaron Kastrinsky establish his gay green push-cart outside the school door set apart for the very little boys and drive a half hour's bustling trade ere the children were all housed. And daily two naughty small boys were convoyed to the door by a red-shawled, dark-eyed sister. Very slowly greetings grew from shy glance to shy smile, from swift drooping of the lashes to swift rise of colour, from gentle sweep of eyes to sustained regard, from formal good-morning to protracted chats. But before this happy stage was reached the twins decided that they no longer required safe conduct to the fountain of knowledge, and that Leah's attendance covered them with ridicule in the eyes of more independent spirits. But she refused to relax her vigilance, nay, rather she increased it; for she began to force her mutinous brothers to the synagogue on Sabbath mornings. The twins soon came to associate the vision of Aaron Kastrinsky with the idea of restraint and of stern virtue, for on the way to the synagogue he walked by Leah's side--looking strangely incomplete without his green push-cart--and drove them by the sheer force of his will to walk decorously in front. Decorously, too, he marched them back again, and stood idly talking to Leah at the steps of her tenement while the twins escaped to their enjoyments.
