Not the least important item in the organization of lay activity is the marvelously rapid growth of the "Young People's Society of Christian Endeavor." In February, 1881, a pastor in Portland, Me., the Rev. Francis E. Clark, organized into an association within his church a number of young people pledged to certain rules of regular attendance and participation in the association meetings and of cooeperation in useful service. There seems to have been no particular originality in the plan, but through some felicity in arrangement and opportuneness in the time it caught like a forest fire, and in an amazingly short time ran through the country and around the world. One wise precaution was taken in the basis of the organization: it was provided that it should not interfere with any member's fidelity to his church or his sect, but rather promote it. Doubtless jealousy of its influence was thus in some measure forestalled and averted. But in the rapid spread of the Society those who were on guard for the interests of the several sects recognized a danger in too free affiliations outside of sectarian lines, and soon there were instituted, in like forms of rule, "Epworth Leagues" for Methodists, "Westminster Leagues" for Presbyterians, "Luther Leagues" for Lutherans, "St. Andrew's Brotherhoods" for Episcopalians, "The Baptist Young People's Union," and yet others for yet other sects. According to the latest reports, the total pledged membership of this order of associated young disciples, in these various ramifications, is about 4,500,000[369:1]--this in the United States alone. Of the Christian Endeavor Societies still adhering to the old name and constitution, there are in all the world 47,009, of which 11,119 are "Junior Endeavor Societies." The total membership is 2,820,540.[369:2]
