THE STORY OF THE GIRLS' BRIGADE INTERNATIONAL   The story of the Girls' Brigade begins with an experience on a chilly Saturday afternoon in the year 1893.   The girls of Sandymount Presbyterian Church, Dublin, had met as usual for their singing practice. Miss Margaret Lyttle was their conductor. The day of the annual Sabbath School Meeting was approaching; there were songs to be learnt and words as well as music to be rehearsed.   Somehow, on this occasion, the singers seemed to be feeling the cold. Perhaps the wind blowing in from Dublin Bay nearby was harsher than usual that day. At any rate, Miss Lyttle thought some physical drill would warm up the members of the group. The effect was immediate. The idea caught on. The girls were delighted and soon began to ask that this drill should in future be a regular part of their Saturday program.   Apparently, some of the girls told their brothers in the Boys' Brigade about this drill and on an afternoon in early October, one girl suggested that the singers should call themselves "The Girls' Brigade".   In this spontaneous way, the name of a great worldwide organization arose. Miss Lyttle could scarcely have imagined that the Girls' Brigade would, in years to come, be represented in each of the five continents by flourishing companies of girls from many nations.   The Girls' Brigade as we know it today, is a combination of three much older organizations for girls which were joined together in July 1965.   These were: The Girls' Brigade formed in Dublin in 1893 The Girls' Guildry formed in Scotland in 1900 The Girls' Life Brigade formed in England in 1902   The Girls' Brigade is an International, Inter-church and uniformed organization. A company may be formed at the request of any Protestant church, recommended by the National Brigade Council of that particular country and approved by the International Headquarters.   Brigade is now operating in 61 countries with a membership of 128,383 as at 1998's statistic. Although we may differ in race and color, language and programs, we have the same AIM, CREST, MOTTO and PRINCIPLES.
