Ten years passed, Carey continued to watch and to extend his agri-horticultural experiments in his own garden, and to correspond with botanists in all parts of the world, but still nothing was done publicly in India. At last, on 15th April 1820, when "the advantages arising from a number of persons uniting themselves as a Society for the purpose of carrying forward any undertaking" were generally acknowledged, the shoemaker and preacher who had a generation before tested these advantages in the formation of the first Foreign Mission Society, issued a Prospectus of an Agricultural and Horticultural Society in India, from the "Mission House, Serampore." The prospectus thus concluded:--"Both in forming such a Society and in subsequently promoting its objects, important to the happiness of the country as they regard them, the writer and his colleagues will be happy in doing all their other avocations will permit." Native as well as European gentlemen were particularly invited to co-operate. "It is peculiarly desirable that native gentlemen should be eligible as members of the Society, because one of its chief objects will be the improvement of their estates and of the peasantry which reside thereon. They should therefore not only be eligible as members but also as officers of the Society in precisely the same manner as Europeans." At the first meeting in the Town Hall of Calcutta, Carey and Marshman found only three Europeans beside themselves. They resolved to proceed, and in two months they secured more than fifty members, several of whom were natives. The first formal meeting was held on 14th September, when the constitution was drawn up on the lines laid down in the prospectus, it being specially provided "that gentlemen of every nation be eligible as members."
