More directly in the central line of advance, and certainly not less romantic in its beginnings, was the extension of the faith to the shores of Cook Strait. Reference has already been made to the evangelising expedition from Tauranga into this country. But before it could have reached its destination, a still more humble agent had been at work, whose position, like that of Taumatakura, was that of a liberated slave, and whose story, like his, begins at the Bay of Islands. It must have been in the year 1836, or somewhat earlier, that the little cemetery at Paihia became the receptacle of the headless body of a Maori who had been killed in a quarrel. With the body came a slave who was now left without an owner. The missionaries took him into house and school, and were pleased with his behaviour. Ripahau showed no signs, however, of becoming a Christian, and after a time asked leave to join a fighting party which was leaving the Bay for Rotorua. He seems to have become known there to Mr. Chapman, but he soon disappeared, and for two years nothing was heard of him. At last, Chapman received from him a letter asking for books. The letter came from Cook Strait, and explained that the people of that neighbourhood were eager to receive instruction. Shortly afterwards two young chiefs from the same quarter presented themselves at the Bay of Islands with a story which thrilled the hearers with wonder and gratitude. To understand its purport it is necessary to cast a backward glance over the years since the early days of the mission, when the Ngapuhi were procuring firearms from traders and missionaries. Hongi was not the only man in those days who foresaw the power which the musket would give. Rauparaha, the young chief of a small tribe living round the harbour of Kawhia on the West Coast, realised that his Waikato neighbours must from their geographical position acquire the precious weapons before his own tribe could do so. The outlook was desperate, and the remedy must be of an heroic nature.
