These leaders, including the teachers of boys' classes, should come together for conference and study at least once a month. The Y.M.C.A. will be the most likely meeting-place, and its boys' secretary the logical supervisor of inter-church activities. Wherever there is no such clearing-house, the ministers' meeting or the inter-church federation may bring the boys' leaders together for co-operation on a community-wide scale. The multiplication of clubs is to be desired, both for the extension of boys' work throughout all the churches, and for the development of such inter-church activities among boys as will make for mutual esteem and for the growing unity of the church of God.
