But there was a duty to the living as well as to the dead. What was to be done for Mr. Grace? The clergy gathered at Bishopscourt asked the question sadly and hopelessly. Even Selwyn was at a loss. At last, Wilson urged that application should be made for the help of the H.M.S. _Eclipse_, then in the harbour. The application was granted, and Captain Fremantle was soon taking the bishop on an errand of rescue. But where was the prisoner to be found? Report said that he had been carried off to Poverty Bay by the Hauhaus, who intended to attack Bishop Williams at Waerenga-a-hika. To Poverty Bay, accordingly, the warship was directed, and there too a critical situation was found. Patara and Kereopa, with their band of fanatics, had just arrived (though not with Mr. Grace) within a few miles of the bishop's residence. A small army of 400 Maoris was drawn up in battle array to defend the bishop, but their minds were divided, and their hearts were faint. Selwyn's exhortations had little effect, but he obtained the help of two loyal Maoris, who undertook to assist in Mr. Grace's rescue. [Illustration: ALL SAINTS' CHURCH, PALMERSTON NORTH.] The _Eclipse_ sailed back to the Bay of Plenty, and anchored outside the bar at Opotiki. It was the sixteenth day of Grace's captivity, and the Hauhaus had agreed to exchange him for a Maori prisoner who was being kept at Tauranga. His treatment lately had been not unkind, but now that the man-of-war appeared, such excitement arose in the _pa_ that his former fears revived. However, the landing of the two messengers from Poverty Bay diverted the attention of the Maoris from their prisoner, who succeeded in getting on board the schooner's boat, and then, by lying down underneath the thwarts, passed down the river unnoticed, and gained the warship outside. Meanwhile the position of the bishop of Waiapu and his family grew daily worse. By the beginning of April all the converts in his immediate neighbourhood had succumbed to the mesmerism of the Hauhaus, and to the effects of a great _tangi_ which they held over the desolation of their country. Accordingly, the bishop, with his family and other members of the mission, left the station on the third of the month and took their way northwards. They soon found a temporary home in the old Paihia buildings at the Bay of Islands, and there the bishop strove to carry on his school, while helping his brother, Archdeacon Henry, in his Sunday duties. The bishop's son, Archdeacon Leonard Williams, remained at Poverty Bay to combat the Hauhau influence, and to shepherd the remnant of faithful Maoris.
