And very thankful did the lads feel to be free of the city and its terrors, albeit they never forgot to offer up earnest prayer for their father and mother and all their dear ones who were dwelling in the midst of so much peril.

There was no hope of hearing news of them, save by hazard, whilst things were like this; but they trusted that the precautions taken, and hitherto successfully, would avert the pestilence from their dwelling, and for the rest the boys were too well employed to have time for brooding.
When their daily work at home was done, there were always errands of mercy to be performed to neighbours who had had sickness at home, or to the persons encamped in the fields, who were very thankful of any little presents of vegetables or eggs or other necessaries; whilst others of larger means were glad to buy from those who came to sell, and gave good money for the accommodation.
Mary Harmer had a large and productive garden and a large stock of poultry, so that she was able both to sell and to give largely; and the boys thought that working in the garden and looking after the fowls was the best sort of fun possible.

They were exceedingly useful to her, and she kept them out of danger without fretting or curbing their eager spirit of usefulness.

Of course, no person in those days could act with unselfish charity and not adventure something; but she took all reasonable precautions, and, like her brother, trusted the rest to Providence.

And she believed that the boys were safer with her, even though not so closely restrained, than they would have been had they remained in the infected city, where the people now seemed to be dying like stricken sheep.
But the spirit of curiosity and love of adventure were not dead within the hearts of the boys; and although for some weeks they were fully contented in performing the duties set them by their aunt, there were moments when a strong curiosity would come over them for some greater sensation, and this it was which led them to an act of disobedience destined to be fraught with important consequences, as will soon be seen.
Mary Harmer's house was empty again, and she had promised to sit up for a night with a sick woman who lived some two miles off, and who had entreated her to come and see her.
