_February 15._--I have been much exercised yesterday and to-day--walking in darkness, without light--and I feel the truth of this Scripture: 'Your sins have separated between you and your God.' I have betrayed a most unbecoming impatience and warmth of temper. My dear absent friend, too, has been much in my mind. How many times have I endured the pain of bidding him farewell! I would not dare repine. I doubt not for a moment the necessity of its being as it is, but the feelings of my mind at particular seasons overwhelm me. My refuge is to consider it is the will of God. Thy will, my God, be done. Henry Martyn did not lose a day in discharging his mission to the residents and slaves of that part of the coast of Brazil, in the great commercial city and seat of the metropolitan. His was the first voice to proclaim the pure Gospel in South America since, three hundred years before, Coligny's and Calvin's missionaries had been there silenced by Villegagnon, and put to death. Martyn was frequently ashore, almost fascinated by the tropical glories of the coast and the interior, and keenly interested in the Portuguese dons, the Franciscan friars, and the negro slaves. After his first walk through the town to the suburbs, he was looking for a wood in which he might rest, when he found himself at a magnificent porch leading to a noble avenue and house. There he was received with exuberant hospitality by the Corrè family, especially by the young Señor Antonio, who had received a University training in Portugal, and soon learned to enjoy the society of the Cambridge clergyman. In his visits of days to this family, his exploration of the immediate interior and the plantations of tapioca and pepper, introduced from Batavia, and his discussions with its members and the priests on Roman Catholicism, all conducted in French and Latin, a fortnight passed rapidly. He was ever about his Master's business, able in speaking His message to men and in prayer and meditation. 'In a cool and shady part of the garden, near some water, I sat and sang, O'er the gloomy hills of darkness. I could read and pray aloud, as there was no fear of anyone understanding me. Reading the eighty-fourth Psalm, O how amiable are Thy tabernacles, this morning in the shade, the day when I read it last under the trees with Lydia was brought forcibly to my remembrance, and produced some degree of melancholy.' Refreshed by the hospitality of San Salvador, he resumed the voyage with new zeal for his Lord and for his study of such authorities as Orme's _Indostan_ and Scott's _Dekkan_, and thus taking himself to task: 'I wish I had a deeper conviction of the sinfulness of sloth.'
