In winter time the nobles repair to Moscow, from all parts of the empire, bringing with them a large train of attendants. Great numbers of the common people, who were engaged during the summer in agricultural labour, return to this great city in the winter, to gain subsistence by different employments. This conflux of people makes the town so full, from the month of December to March, that the population, at this season, amounts, according to some computations, to two hundred and fifty thousand; according to others, to three hundred thousand. In the month of March, people begin to go into the country again; hence, during the summer, the number of inhabitants is, at least, one-fourth less than in winter. In 1771 the fear of catching the plague had caused a much greater number to leave the city; so that I do not think that, in the month of August, there were more than one hundred and fifty thousand remaining in the place. An idea may be formed of the destructive nature of this disorder, and the terrible activity of its poison, by reflecting, that of these one hundred and fifty thousand inhabitants, twelve hundred were daily carried off by it, (in the month of September!) The number of deaths kept at this rate for some days, and then diminished to one thousand. As the populace, during the riots, had re-established all the religious ceremonies customary on burying the dead, almost all their priests, deacons, and other ecclesiastics, fell victims to the contagion.

The people, brought to a sense of their duty, partly by the rigorous measures employed against them, and partly by seeing that the public calamity had been aggravated by their disorderly proceedings, now began to implore our assistance. The monasteries and other pest-houses were full; the sick were no longer carried thither; the contagion had spread every where; insomuch that the city itself might be considered as one entire hospital. All, therefore, we could now do, was to exhort every individual to take care of himself; to warn all those who were yet free from the contagion, to avoid, as much as possible, touching with their bare hands any infected person; to direct them to burn the clothes, and every thing else that had been used by those who had been ill of the plague; and, lastly, to keep their rooms clean and well aired.

At this time Count Gregory Orlow[22] arrived at Moscow, invested with full powers by the empress. I received an order, in common with the other physicians, to deliver, in writing, my private sentiments on the subject; we were required to turn our attention principally to the most proper measures for destroying the contagion[23]. Having taken the necessary steps to prevent all further popular commotions, the Count selected, from all our papers, what appeared of most moment, and drew up a set of regulations, as well for the treatment of the sick, as for the keeping of those who were yet well, free from infection. He also ordered new hospitals to be immediately built for the reception of the poor seized with the plague[24].

Some months had elapsed since the plague had been carried to many of the villages, as well in the vicinity as at a distance from Moscow. Persons who fled from this city had also carried it with them to Kalomna (Kaluga, according to Orræus), Yaroslaw, and Tula. Inspectors of health, attended by physicians and surgeons, were sent to these infected towns and villages.

A Council of Health was formed, composed of General Yeropkin (who was president), of some counsellors of state, and of three physicians, and one surgeon. This council received daily reports from the physicians and police-officers, and took cognizance of every thing which related to the health of the inhabitants. Two physicians, Drs. Pogaretzky and Meltzer, being offered a reward of one thousand roubles, undertook, each of them, the care of a pest-hospital; and went thither accordingly.

On the 10th of October the frost set in; from that day the disorder was less fatal, and the contagion became more fixed. The number of sick and dead gradually diminished; and the disorder, which a short time before had terminated on the second or third day, now kept on to the fifth or sixth. Neither those large purple spots, which we have before described, nor carbuncles, were by any means so frequent as they had been; buboes were now almost the only tumours found upon the infected.

The hard frost[25] which prevailed during the two last months of the year, weakened the pestilential virus to such a degree, that those who attended the sick and buried the dead were in much less danger of being infected; and when they were infected, the symptoms were much milder; so that at this period, several persons who had the plague were but slightly indisposed, and walked about though they had buboes upon them.

At the close of the year 1771, this dreadful scourge ceased, by the blessing of God, at Moscow, and in every other part of the Russian empire. Besides the three towns before-mentioned, upwards of four hundred villages had been infected.

The weather was intensely cold during the whole of the winter. In order to destroy all remains of the contagion, the doors and windows of the rooms in which there had been any persons ill of the plague, were broken and the rooms were fumigated with the antipestilential powder[26]; the old wooden houses were entirely demolished. The effects of the plague were traced in every part of the city. Even as late as the month of February, 1772, upwards of four hundred dead bodies were discovered, which had been secretly buried the year before in private houses. So powerful is cold in destroying the contagion, that not one of those who were employed in digging up these bodies, and carrying them to the public burying-grounds, became infected[27].
