Read the excerpt from Immigrant Kids by Russell Freedman. Now the examinations began. First the immigrants were examined by two doctors of the United States Health Service. One doctor looked for physical and mental abnormalities. When a case aroused suspicion, the immigrant received a chalk mark on the right shoulder for further inspection: L for lameness, H for heart, X for mental defects, and so on. The second doctor watched for contagious and infectious diseases. He looked especially for infections of the scalp and at the eyelids for symptoms of trachoma, a blinding disease. Since trachoma caused more than half of all medical detentions, the doctor was greatly feared. He stood directly in the immigrant’s path. With a swift movement, he would grab the immigrant’s eyelid, pull it up, and peer beneath it. If all was well, the immigrant was passed on.
