We would refer to the effort made in the national exhibitions of the various countries, where the societies of the Red Cross have displayed their practical improvements and inventions in competitive fields, taxing to the utmost human ingenuity and skill. Some countries have taken grand prizes. An exposition at The Hague was held in 1867 exclusively for the work of the Red Cross. Permanent museums have been established where all sorts of sanitary material for relief are exhibited, as may be seen in Stockholm, Carlsruhe, St. Petersburg, Moscow and Paris. The museum of Paris is the most important of all, and is international, other countries having participated in its foundation. Another method is the publication of works bearing upon this subject, some of which are scientific and very valuable. Not less important is the sanitary personnel. Of all aid, efficient nurses are the most difficult to obtain. There are numbers of men and women who have the will and devotion necessary to lead them into hospitals or to battlefields, but very few of them are capable of performing well the duties of nurses. Therefore, but a small portion of the volunteers are available. The relief societies soon found that women were by nature much better fitted for this duty than men can be, and to enable them to fulfill to the best advantage the mission for which they are so well adapted, it was decided to afford them the best possible professional instruction. For this purpose, during peace training schools were established from which were graduated great numbers of women who are ready at a moment's notice to go upon the battlefield or into hospitals. These professional nurses find no difficulty during times of peace in securing remunerative employment. Indeed, they are eagerly sought for by the community to take positions at the bedside of the sick, with the proviso that they are to be allowed to obey the pledge of their society at the first tocsin of war. There are schools for this purpose in England, Germany, Sweden, Holland, Russia and other European countries, and nothing has been neglected to make them thorough and to place them on a strong and solid basis.
