"I very much fear that many of those who preach the gospel in this country will blush when the Saviour calls them to give an account of their labors in His cause, and tells them, 'I commanded you to go into all the world, and preach the gospel to every creature.'" And with the most forcible emphasis he exclaimed, "The Saviour may ask, 'Where have you been? What have you been doing? Have you endeavored to the utmost of your ability to fulfil the commands I gave you? or have you sought your own gratification and your own ease, regardless of my commands?'" In his new home, his intellectual ability, firmness of purpose, unbending integrity, correct judgment, and disinterested benevolence, caused him to be beloved and respected, and gave him great influence: and he soon rose to honorable distinction. The interests of the colony, and the cause of his countrymen, in both Africa and America, were very near to his heart. For them he was willing to toil, and to make almost any sacrifice; and he frequently declared that no possessions in America could induce him to return. He possessed a constitution peculiarily fitted for toil and exposure, and he felt the effects of the climate perhaps less than any other individual in the colony. During the sickly season of the year, he was usually wholly employed in attending the sick; and for more than a year, they had no other physician among them. The little medical information he had obtained from Dr. Ayres and others on the coast, together with several years' experience, enabled him successfully to contend with the peculiar fevers of the climate. Under date of March 12th, 1824, shortly after the arrival of the Cyrus with 105 emigrants, he wrote: "The fever began about the 24th ult., and on the 28th we had thirty-eight cases; and by the 2d inst. we had sixty-six under the operation of medicine; and at present, I have about a hundred cases of fever to contend with; but we have been very much favored, for they all appear to be on the recovery, and we have lost none, saving three children. I have very little time to write to you, myself being the only man that will venture to act in the capacity of a physician." The managers of the American Colonization Society, in 1825, invited Carey to visit the United States, in the expectation that his intelligent and candid statements, concerning the condition and prospects of the colony and the moral wants of Africa, would exert a beneficial influence on the opinions of the people of color, and recommend the cause of the society to the public regard. In the month of April, 1826, he made arrangements to embark in the Indian Chief, on her return from taking a large number of emigrants to the colony, and received from Ashmun testimonials of his worth and services. The following is an extract from a letter from Ashmun to the managers of the Colonization Society:
