In 1845 Miss Dix reported that in three years she had travelled ten thousand miles, visited eighteen state penitentiaries, three hundred jails and houses of correction, and five hundred almshouses and other institutions, secured the establishment or enlargement of six hospitals for the insane, several county poorhouses, and several jails on a reformed plan. She visited every state east of the Rocky Mountains, and also the British Provinces, to secure legislation in behalf of the insane. She secured the erection of hospitals or other reformatory action in Rhode Island, New Jersey, Pennsylvania, Indiana, Illinois, Kentucky, Tennessee, Missouri, Mississippi, Louisiana, Alabama, South Carolina, Nova Scotia, and Newfoundland. Her labors also secured the establishment of a hospital for the insane of the army and navy, near Washington. All this was the work of nine years. In 1853 Miss Dix gave her attention to providing an adequate life-saving equipment for Sable Island, one of we most dangerous places to seamen on the Atlantic coast; and this became the means of saving many lives. In 1854 she went to England for needed rest; but almost at once she took up her humanitarian work, this time in Scotland, where she secured a commission of inquiry, which in 1857 resulted in reformatory legislation on the part of Parliament. In 1855 she visited the island of Jersey, and secured great improvements in the care of the insane. Later in that year she visited Switzerland for rest, but in a few weeks was studying the charities of Paris and then those of Italy. In Rome she had two interviews with the pope, and the erection of a new hospital for the insane on modern principles resulted. Speaking only English, and without letters of introduction, she visited the insane hospitals and the prisons of Greece, Turkey, Austria, Sclavonia, Russia, Germany, Sweden, Norway, Denmark, Holland, and Belgium. "Day by day she patiently explored the asylums, prisons, and poor-houses of every place in which she set her foot, glad to her heart's core when she found anything to commend and learn a lesson from, and patiently striving, where she struck the traces of ignorance, neglect, or wrong, to right the evil by direct appeal to the highest authorities." On her return home, in September, 1856, she was met by many urgent appeals for help in enlarging hospitals and erecting new ones; and she devoted her time until the outbreak of the civil war in work for the insane in the southern and middle north-western states. As soon as the troops were ordered to Washington, she went there and offered her services as a nurse, and was at once appointed superintendent of women nurses for the whole army. She carried through the tasks of this office with energy and devotion. In 1866 she secured the erection of a monument to the fallen soldiers in the National Cemetery, at Hampton.
