A large tract of new territory was now open to outside influences. Who was to be the first to settle in it--official, trader, or missionary? Mary studied the situation again in the light of the new conditions, obtaining information first-hand from officials and natives. There were two stations on the west of the Cross River--Ikorofiong, which, however, was really an Efik trading town, and higher up, Unwana, which was a back-water and unfit for a base for inland work. Tentative efforts had been made from time to time to secure a footing elsewhere, but had come to nothing, and the policy of the Mission had been to continue up-river as being the line of least resistance. Her conviction was that extension, for the present at least, should take place not up the river, where the stations were cut off from the base during the dry season, but laterally across the country between the Cross River and the Niger. There were, she saw, three strategetic factors which dominated the situation--the Enyong Creek giving admission to the new territory, Itu at its mouth, and Arochuku, the religious and political centre of the Ibos. The central position of Itu impressed her; it commanded the three contiguous regions and peoples--the Ibo, Ibibio, and Efik, and her plan was to seize and hold it as a base, then one of the towns of Arochuku as the threshold of Iboland, and, if possible, Bende. Her views did not commend themselves to all her colleagues in Calabar, but how wise, how far-seeing, how statesmanlike was her policy the later history of the Mission proves.
She felt she could do nothing until help was obtained for Akpap. Fortunately there was one lady missionary in Calabar who had the courage to prefer Okoyong to quieter stations-Miss Wright of the Girls' Institute, who asked the local Committee to send her there as assistant to Miss Slessor; and although the Committee approved, the matter was referred to the Women's Committee at home. As there seemed no prospect of anything being done, she began to move quietly along her own lines. Her school lads were now old enough and educated enough to be used as advance agents, and her hope lay in these. In January 1903 she left Akpap with two boys, Esien and Effiom, and one of her girls, Mana, and canoed to Itu, and planted them there to teach school and hold services. Esien took the chief part in the latter, whilst Effiom led the singing. Mana's work was the teaching of the girls. A few weeks later she found that the results had exceeded all her dreams. The chief said he was too old to change his ways, but the younger ones could learn the new ideas--anyway God had made him, and so was bound to look after him whatever sins he committed. But the children were eager to learn, and made apt scholars, and the people crowded to the services until there was no more room for them. She went up again and selected a site on the top of the hill with a magnificent view and built a school, speeding the work with her own hands, and set the willing people to construct a church, with two rooms for herself at the end. When one of her fellow-missionaries, Dr. Rattray, heard of this he wrote: "Bravo! Uganda was evangelised by this means, and the teachers there could only read the gospels and could not write or count; the Mission understood its business to be to spread the Gospel, and all who could read taught others and spread the news. Perhaps we educate the people too much, and make them think that education is religion."
