SECTION VII. Historical view of pestilential epidemics from the year 1701 to 1788.
THE year 1701 appears to have been excessively dry in America. Dr. Rush relates that during the dry summer of 1782, a rock in the Skuylkill appeared above the surface of the water, on which were engraven the figures 1701. How little do men suspect the value of this inscription! To this alone I am indebted for the fact of extreme drouth in that year—and the fact is among the proofs of an extraordinary evaporation, before dis|charges of fire and lava from volcanoes. In 1701 was an erup|tion of Vesuvius; in 1702 of Etna. It will hereafter appear that a similar dry season in 1782 preceded the great eruption of Heckla in 1783. Indeed it is a general fact, and as far as I can learn, such seasons seldom occur, except during the approach of comets, or antecedent to volcanic eruptions.
This was a pestilential period. In 1701 Toulon lost two thirds of its inhabitants by the plague, and the Levant was se|verely affected about the same time. See the bills of mortality for Augsburg, Dresden and Boston.
In 1702 appeared a comet; Etna discharged its fires, and in Boston raged a malignant small-pox, attended, in many cases, with a scarlet eruption, which was mistaken for the scarlet fever. It appears from Fairfield's diary that this disease appeared in June and was at first mild, not fatal to any of the patients. In August died one patient—in September it became very mortal, and in this month was attended with a "sort of fever called scarlet fever." In October, many died of the "fever and the small-pox, and it was a time of sore distress," on which account the general court sat at Cambridge. In December "the fever
