“At that time,” says the medical officer of the city, “I felt assured that the poison which produced cholera pervaded the city; that it was brooding over us; that we were already under its influence, and I anticipated momentarily an outbreak of the epidemic. In about two weeks, however, from the commencement of this diarrhœa, and the prevalence of the uneasy sensation which accompanied it, these symptoms began to subside, and in a short time they wholly disappeared. Simultaneously with their disappearance, cholera broke out at Richmond, and other towns south of Baltimore. I then felt assured that the fuel necessary to co-operate with this poison did not exist in our city: that the cloud had passed over us and left us unharmed.” No case of cholera was reported to the Board of Health or other authorities of the town as having occurred during this time; but on close examination, it was ascertained that four deaths had taken place from the disease in its most virulent form. That the cholera poison had really pervaded the city, was appallingly evinced by an event which occurred in its immediate vicinity. The Baltimore almshouse is situated about two miles from the city, on sloping ground, remarkable for its beauty and salubrity, in immediate contiguity with the country-seats of several of the wealthy families of the town. It is surrounded by a farm of upwards of 200 acres, belonging to the establishment, for the most part under cultivation. The building is capable of accommodating between 600 and 700 inmates. An enclosure of about five acres, surrounded by a wall, adjoins the main building upon its north side. In the rear of this north wall is a ravine, which at one point approaches the wall to within about nine feet. This ravine is the outlet for all the filth of the establishment. It is dry in summer, but retentive of wet after rain. The space between the wall and the bed of the ravine is not under tillage, but is overgrown with a rank, weedy vegetation, common in rich waste soils. The physician of the establishment, under the same apprehension of an outbreak of cholera as had prevailed in Baltimore, had taken the same precautions against the disease, and had placed the establishment itself in a state of scrupulous cleanliness. On the first of July cholera attacked one of the inmates. On the seventh a second attack occurred. This was followed in rapid succession by other seizures, and within the space of one month 99 inmates of the establishment had perished by cholera.
