Returning down the river, a site was chosen for a station at Puriri. The spot lay amongst flax swamps on a tributary of the Thames. It was somewhat damp and unhealthy, but it was centrally situated as regards the tribes of the neighbourhood. Before the end of the year it was occupied by Morgan, Preece, and Wilson, who found raupo houses already erected for them by the Maoris.

The Thames expedition had proved beyond a doubt that the land lay open to mission enterprise. But the surprises which it offered were not always pleasant ones. Early in the year 1836 Brown and Hamlin, with some Maori converts, started overland to explore the Waikato. The Kaipara and Tamaki districts were waste and uninhabited, nor were any human beings seen, till they struck the great river itself. In the absence of canoes they essayed to cross it on mokis or bundles of flax-stalks. These rafts were so satisfactory that they paddled down the stream for some distance, when they were met by a boat containing an Englishman and a younger brother of Te Wherowhero—afterwards well known as the Maori King, Potatau. The strangers were friendly, but their remarks were uncomfortably direct. "Why did you not come before?" they asked. "You have stayed so long in the Bay of Islands that surely your children are old enough to be missionaries. If you had come among us some time ago, the Taranakis would have been alive, but now we have cut them nearly all off."

The opening thus indicated could no longer be neglected. A few months later a second expedition was directed towards the same quarter, though by a different route. It consisted of Messrs. W. Williams, Brown, and Morgan, and they had with them the speaker of the sharp rebuke above mentioned. Approaching from the side of the Thames Valley they reached Ngaruawahia, at the confluence of the Waikato and Waipa rivers. Boating up the Waipa until they could pull no longer, they landed at Mangapouri near Pirongia. So pleased were they with the place that they decided to fix a station there. The local chief at once offered land, and set men at work to clear it, though a few months necessarily elapsed before it could be actually occupied.

Mr. Williams and his colleagues meanwhile journeyed back into the Thames Valley, and, after promising Waharoa to send him a teacher as soon as possible, passed on to the Bay of Plenty. At Tauranga a large gathering of the inhabitants was held. They had evidently not forgotten the efforts which had been made four years before by Henry Williams to save their settlement from the wrath of the Ngapuhi. They had come to realise that the missionaries actually cared for other tribes as well as for the favoured Ngapuhi; they felt that a mission station would help in the preservation of peace; and they undertook to build houses in readiness for the teachers who should come.

The year 1835 saw the opening of the four new stations. Hamlin and Stack settled at Mangapouri; Brown and Morgan at Matamata; Wilson at Tauranga; and Chapman near Ohinemutu, amidst the hot springs and geysers of Rotorua. It will be noticed that these frontier posts were occupied mainly by the new men who had not acquired much knowledge of the language or of the customs of the Maori. Some misunderstandings were bound to arise from this cause, and Wilson nearly lost his life at Puriri, but soon a more peaceful state of things ensued. Everything seemed bright and hopeful when, on Christmas Day, a horrible murder occurred at Rotorua, which kindled a fresh war, and threw the work into confusion for several years.

The details of the war lie, of course, outside our subject: it will suffice to notice those points at which it touched the missionary band. The Rotorua station was naturally the first to feel its effects. Mr. Chapman did his utmost to check the outbreak of hostilities, and having secured the head of the murdered man he had it conveyed to the relatives. But the victim was a chief of high rank and nearly related to Waharoa. It was incumbent therefore upon that redoubtable warrior to obtain utu for the slaughter of his relative. He was still a heathen, and was deaf to the exhortations of the Christians. "How sweet," he said, "will taste the flesh of the Rotoruas along with their new kumeras!" It was not long before he was able to gratify this wolfish taste, and in the confusion which followed the assault upon the Ohinemutu pa the missionary premises were looted. They were at the time in charge of two young assistants, Knight and Pilley—the former being a nephew of Marsden. Both were felled to the ground, wounded and stripped of their clothes. Chapman and his wife were fortunately absent. Mrs. Chapman after many dangers reached Matamata, but the tide of war rolled thither also, and the mission ladies were hurried through the swamps to the river bank. Here they were met unexpectedly by Fairburn and Wilson, who had been rowing up the Waihou for the last two days in the endeavour to bring help to their colleagues at Rotorua. Wilson in his journal thus describes the meeting: "River covered by a thick fog, everything dripping wet. After rowing a few miles in the early morning we came to a small sandy landing place. Here, under some canvas thrown over the shrubs, we found Mr. Morgan and three missionaries' wives—Mesdames Brown, Chapman, and Morgan—and with them two or three native girls (bearers of their luggage from Matamata). These poor ladies had all the appearance of fugitives, and such they really were. They had slept in their clothes on the wet ground, and their chief comfort was a little fire struggling for existence with wet green wood. On hearing the noise of our boat landing, I saw from under the canvas a weary pale face, nearly on a level with the wet earth, looking to see what it was. How glad they were to see us! What a change in their countenances from sorrow to gladness! Now—for a time at least—their troubles were over. In a few minutes we had them packed and arranged in our little boat, and sent them down the Waihou on their way to the Puriri."

Though the ladies had escaped unharmed, their belongings had not. The Matamata station was no safe place for anything, on account of the marauding bands who infested the country. As soon as possible therefore the most valuable articles were packed and sent off towards the river. News soon arrived that the convoy had been plundered. Morgan and Knight set out in pursuit and encountered a band of armed men, whose grotesque appearance brought a laugh to the missionaries' faces in spite of the danger of the situation. Most of the party were dressed in white shirts, and "one man was marching before the rest, with the utmost consequence, his head and olive-coloured face being enveloped in a black silk bonnet belonging to Mrs. Chapman, while a strip of cotton print, tied round his neck, formed the remainder of his apparel—he having left his own clothes at home, in order to his being lighter for fighting or anything else he might have to do."

The humour of the moment was not lessened when it was found that the strangely clad procession consisted not of the actual robbers, but of a friendly party who had robbed them in turn. The hero of the bonnet episode was, in fact, a son of Waharoa, who shortly afterwards embraced Christianity, and under the new name of Wiremu Tamihana (William Thomson) witnessed a good confession in the midst of his savage compatriots, and actually built a new pa, in which he allowed no one to live who did not join with him and his followers in worshipping God and in keeping the elementary rules of morality.

Troubles continued to thicken, but the missionaries clung to their posts as long as they could. Wilson went to the help of Chapman at Rotorua, and together they retired across the lake to the island which has become famous through the legend of Hinemoa. The beauty of its traditions could hardly be appreciated by the fugitive missionaries: "The hut in which we live," they wrote, "is small and damp, has neither chimney nor window, and on rainy days, which confine us inside, we construct a lamp with lard and cotton to read by, as best we can." But Chapman, like his wife, never complained. Without a word of reproach or repining, he took his friend over the ruins of the old station, which he had made the most beautiful of all the mission properties. His one desire was to make peace among his people, and for this purpose he sent once and again to Henry Williams for his help. But even Wiremu, with all his efforts, could not soften the heart of Waharoa nor of the Rotorua leaders. The war accordingly went on, though now in desultory fashion. The Matamata station was finally stripped, and its occupants driven to the north. The Committee now withdrew Chapman to Tauranga, and finally with Wilson to the Bay of Islands. They arrived there at about the same time as did the refugees from the Thames.

The forward movement appeared thus to issue in failure. But the abandonment was not for long, nor had the work already done been in vain. Waharoa died a heathen, but he complained before his death that his sons, under mission influence, were becoming too mild and forgiving. The case of one of these—Tamihana—has already been noticed. Still more remarkable is that of his warlike nephew, Ngakuku, whose name brings us to one of the most touching incidents in the history of Maori Christianity.
