The extensive and splendid missions of this board originated with the Rev. David Bogue, while on a visit to London. From his suggestions, the society was formed, in 1795, by several ministers of various denominations.

SOUTH SEA ISLANDS. -- The society commenced their labors among these isles by sending out thirty-six missionaries, in 1796, who arrived safely, and commenced their duties at Otaheite, Tongataboo, and St. Christina, in March, 1797. Subsequently, they spread their influence over nearly all the islands of the Pacific Ocean. These missions have been eminently successful.

NEW SOUTH WALES. -- This mission was begun by the labors of Mr. Threlkeld, in 1826, in Bahtabee, on Lake Macquaire.

SOUTH AFRICAN MISSIONS. -- The success of the missions in the islands of the Pacific and South Seas, turned their attention to this dark land. Dr. Vanderkemp, who was their first laborer, began his labors on the River Keis Kamma, in Caffraria, in 1799. In 1801, he removed to Graff Reinet, and preached to the Hottentots in that vicinity. These missions afterwards spread very widely among the Caffres and Hottentots.

EAST INDIAN MISSIONS. -- The society's missions in this most interesting quarter of the globe were commenced at Calcutta and Chinsura, by the Rev. Mr. Forsyth, in 1798. Subsequently, their stations spread over Northern and Peninsular India, India beyond the Ganges, into China, Siam, and some of the Asiatic Isles.

GUIANA AND WEST INDIES. -- At the request of a pious Dutch planter, Mr. Wray was sent to Demerara, in Guiana, in 1807. This was the beginning of the society's operations in South America.

OTHER MISSIONS. -- Beside these, are the European and Mediterranean islands missions, which, though of recent date, are promising in their aspects.

EDUCATION. -- This society has several presses distributed over the vast field occupied by their agents, by means of which millions of pages are annually scattered among the people. They publish tracts parts of the Scriptures, &c. &c. They have also upwards of four hundred native assistants, which are not mentioned in the following summary.

Summary.

From the best accounts we can obtain, this society had, in 1840, in Asia, the South Sea Islands, Africa, Guiana, and in Europe, about five hundred and fifty missionary stations and out-stations, one hundred and sixty-four missionaries, five thousand communicants, and about twenty-five thousand scholars.
