Under the leadership of Mary Creswell and J. Phil Campbell, Georgia 4-H Clubs grew from 350 members in 1910 to 27,000 in 1920. It wasn't until 1924 when club work acquired the name of 4-H and the 4-H emblem was patented. In 1927, state 4-H leaders adopted the national 4-H pledge and the 4-H motto at the first National 4-H Club Camp. In 1933, Georgia started the first Wildlife Conservation Camp. P. H. Stone became the first Negro state 4-H leader in Georgia in 1924. By 1937, Georgia has county agents working in every county and 4-H enrollment had grown to 82,962. Land was acquired in 1939 in Dublin, Georgia, to build the Negro 4-H Center. The center had 150 meetings for 5,000 people annually. The headquarters for black Extension work was at Savannah State College until 1967.
