"It is our impression," said Dr. T.L. White, assistant to the State Board of Health, this morning, "that there is going to be great sickness here within the next week. Five cases of malignant diphtheria were located this morning on Bedford street, and as they were in different houses they mean five starting points for disease. All this talk about the dangers of epidemic is not exaggerated, as many suppose, but is founded upon all experience. There will be plenty of typhoid fever and kindred diseases here within a week or ten days in my opinion. The only thing that has saved us thus far has been the cool weather. That has now given place to summer weather, and no one knows what the next few days may bring forth." Fresh Meat and Vegetables Wanted. Even among the workmen there is already discernible a tendency to diarrhoea and dysentery. The men are living principally upon salt meat, and there is a lack of vegetables. I have been here since Sunday and have tasted fresh meat but once since that time. I am only one of the many. Of course the worst has passed for the physicians, as our arrangements are now perfected and each corps will be relieved from time to time. Twenty more physicians arrived from Pittsburgh this morning and many of us will be relieved to-day. But the opinion is general among the medical men that there will be more need for doctors in a week hence than there is now. Sanitary Work. Dr. R.L. Sibbel, of the State Board of Health, is in charge of Sanitary Headquarters. "We are using every precaution known to science," said he this morning, "to prevent the possibility of epidemic. Our labors here have not been confined to any particular channel, but have been extended in various directions. Disinfectants, of course, are first in importance, and they have been used with no sparing hand. The prompt cremation of dead animals as fast as discovered is another thing we have insisted upon. The immediate erection of water-closets throughout the ruins for the workmen was another work of the greatest sanitary importance that has been attended to. They, too, are being disinfected at frequent intervals. We have a committee, too, that superintends the burial of the victims at the cemeteries. It is of the utmost importance in this wholesale interment that the corpses should be interred a safe distance beneath the surface in order that their poisonous emanations may not find exit through the crevices of the earth. "Another committee is making a house-to-house inspection throughout the stricken city to ascertain the number of inhabitants in each standing house, the number of the sick, and to order the latter to the hospital whenever necessary. One great danger is the overcrowding of houses and hovels, and that is being prevented as much as possible by the free use of tents upon the mountain side. So far there is but little contagious disease, and we hope by diligent and systematic efforts to prevent any dangerous outbreak."
