Miss More’s prolonged life did not close until 1833, when she had arrived at her eighty-ninth year.  The thirty-one years that remained to her after quitting Cowslip Green was as full of work and usefulness as the previous part of her life.  It will be impossible within the space now left to do more than indicate the chief events of this period, which was not remarkable for any fresh departure either in educational or religious work.  Miss More had already marked out for herself two distinct and definite lines of usefulness—­the education of the poor, and the improvement of morals and religion amongst the rich.  By her active exertion and by her busy pen she continued to pursue these two lines of work down to the year of her death.  It must be remembered that she was a martyr during these latter years to long attacks of illness, one of which almost completely prostrated her for two years; and when upwards of seventy she was unable to leave the house for more than seven years.  At this period she stated that she had never been free from pain for long together since she was ten years old.  Such physical hindrances render her persistent activity and the great work she accomplished all the more remarkable.  When not entirely incapacitated she still worked with her pen, attended to business connected with her schools, and received visitors in the sick room.  It used to be said amongst her friends that when she was laid aside they always expected a new book from her.

In 1805 she published Hints towards forming the Character of a Young Princess.  It was undertaken, at the request of a bishop, with reference to the education of the Princess Charlotte.

In 1809 her religious novel, Coelebs in Search of a Wife, issued anonymously, roused universal attention.  In twelve months as many editions came out; and during the author’s lifetime thirty editions of a thousand copies each were printed in America.  This was followed shortly by Practical Piety, which soon ran to the tenth edition, and which brought the author to the end of her life numerous gratifying testimonies of its results.  As a sequel to this work, Christian Morals was published in 1812, and was also widely circulated.  Three years later, when the author had entered her seventieth year, she wrote an Essay on the Character and Writings of St. Paul, in two volumes, which, notwithstanding absorbing political events, was received with the same eagerness which greeted her former works. Moral Sketches of Prevailing Opinions and Manners, Foreign and Domestic, was published in 1819, being chiefly directed against the rage for copying French customs and manners.  At the age of eighty-two she collected from her later works her Thoughts on Prayer and re-issued them in a little volume, with a short preface.  This was her last literary effort.  She said to a friend that the only remarkable thing which belonged to her as an author was that she had written eleven volumes after the age of sixty.
