Dr. Barton W. Brush is engaged in reconstruction work in Serbia, under the Serbia Relief Committee of New York. He went there in July, promising to serve fifteen months, and taking with him twenty physicians and nurses. He is at the head of the medical staff. He has started several dispensaries in various towns, and is now located on a mountain side in a small town where he has established a hospital of thirty beds, a dispensary, and a health center, where he teaches sanitation and nursing to Serbian women. He is the only medical man for many miles around, and ministers to a population of 32,000 souls. He has just finished with an epidemic of scarlet fever with 300 cases, and is now fighting typhus.
