The voyage lasted long enough to improve them in English, for they did not cast anchor at Tranquebar till the 8th of October.
At this considerable Danish factory, they were received into the mission- house of the Danes, and there remained while studying the language, in which Schwartz made so much progress that he preached his first Tamul sermon only four months after his arrival, and by the spring was able to catechize the children who attended the school.

This station at Tranquebar formed the home of seven or eight missionaries, who lived together, attended to the services and schools, prepared candidates for baptism, and made excursions by ones and twos into the villages that stood thickly on the coast, where they talked and argued with the natives, hoping to incite them to inquire further.

The two greatest obstacles they met with here were the evil example of Europeans and the difficulty of maintenance for a convert.

One poor dancing girl said, on hearing that no unholy person could enter into the kingdom of heaven, "Ah! sir, then no European will;" but, on the whole, they must have met with good success, for in 1752 there were three large classes of catechumens prepared and baptized at the station.

In the district around there were several villages, where congregations of Christians existed, and, of all those south of the river Caveri, Schwartz was after two more years made the superintendent.
The simple habits of these German and Danish clergy eminently fitted them for such journeys; they set out in pairs on foot, after a farewell of united prayer from their brethren, carrying with them their Hebrew Bibles, and attended by a few Christian servants and coolies; they proceeded from village to village, sometimes sleeping in the house of a Hindoo merchant, sometimes at that of one the brother ministers they had come to see, and at every halt conversing and arguing with Hindoo or Mahometan, or sometimes with the remnants of the Christians converted by the Portuguese, who had been so long neglected that they had little knowledge of any faith.
The character of Christian Schwartz was one to influence all around him.
He seems to have had all the quiet German patience and endurance of hardship, without much excitability, and with a steadiness of judgment and intense honesty and integrity, that disposed every one to lean on him and rely on him for their temporal as well as their spiritual matters--great charity and warmth of heart, and a shrewdness of perception that made him excellent in argument.
