SCHOOLS AID IN CONSUMPTION FIOHT.

Children Are Taught How to Prevent Disease.

New York, Dec. 3.�As a result of the great campaign against

tuberculosis now being carried on throughout the world, many of the

public schools in the United States are taking a new departure in

teaching to the children the nature, causes, dangers and preventionof consumption. A text-book entitled "Simple Lessons on Tuberculosisor Consumption" has just been placed in the seventh and eighth gradesof the District of Columbia. The Massachusetts educational authori-

ties, acting under a law of the Legislature of 1908, are establishing

courses of instruction on tuberculosis in all of the schools of thestate. In addition to these public movements many of the privateorganizations throughout the country have established, and are es-tablishing, open-air schools for consumptive children, it being estimatedthat about two per cent of the pupils in the larger city schools havetuberculosis.The first public school for consumptive and pro-consumptive children

to be established in the United States was opened in Providence, R. I.,last January. The sessions were held entirely in the open, and thebenefits of the fresh-air treatment were combined with the teachingand training of the public schools.This experiment led to other movements, both public and private,

The Brookline Anti-Tuberculosis Society opened a school for tuber-culous children in July which is still successfully conducted. InBoston a school for consumptives was opened under private auspicesin July, it being the intention to keep it open for the summer months

only, but so successful were the results of this work that the city

school authorities recently decided to take over the work and setaside a permanent building for this purpose. In Pittsburg a similarschool was opened in September, and the marked benefits which thechildren have already received from this training have led to itsenlargement. The Board of Education of New York City has justgranted a teacher to the Bellevue Hospital Day Camp for the purposeof conducting a school there, and a consumptive teacher has been se-cured to teach the consumptive children. This school will be con-ducted on the deck of an old ferry-boat. In all of these schoolsthe children are kept in the open air all day long. Most’ of thebuildings used are opened on three sides and are so constructed as- tofurnish unlimited supplies of fresh air without draughts. Desks,blackboards, and other paraphernalia are provided in these schoolsjust the same as in the regular institutions. The children study andrecite in the open air, even during the coldest weather, and’ thepercentage of colds among them is far smaller than children in theordinary public schools. In most of these fresh-air schools soapstonesare provided for keeping the feet warm in cold weather.In addition to these specially constructed schools several of the

States have required that the important facts about tuberculosis betaught in the lower grades of the public institutions. Michigan wasthe first State to adopt measures of this kind. By an act of 1895,the public schools are required to give instruction on the nature oftuberculosis and other infectious diseases. In New Jersey progressivesteps are being taken by teaching the children in the schools a setof aphorisms on consumption. In Massachusetts a section on thenature, dangers and prevention of consumption is being inserted inall of the physiologies. In the District of Columbia a special text-book has been provided in which instruction is given concerningsleeping in the open air, the dangers of spitting, the way to preventconsumption, and other kindred topics. Dallas, Tex., is the latest cityto adopt the method of teaching children about consumption in theschools, and within a few days a "Tuberculosis Primer" will be inthe hands of every pupil in the public schools. In North Carolina aseparate section on tuberculosis, placed in all the physiologies, istaught to all of the children. In Baltimore steps are being taken tocarry on a systematic campaign of education among the school childrenby means of lectures and circulars. Many other cities of the countryare following this plan. A petition has been sent to the Governor ofSouth Carolina requesting that a text-book on tuberculosis, similar tothat. used in Washington, be placed in the public schools. Several ofthe other States are also taking steps along similar lines.This movement for the popular education of school children on thp

causes and dangers of consumption is receiving a great impetus, andexperts on this subject conclude that within five years the majorityof children in the United States will be’taught concerning the evilsand dangers of tuberculosis before they leave the lower grades of thepublic schools.
