came over to General Arnold and agreed with him to a cartel by which certain prisoners were exchanged. The American prisoners were returned in a destitute and forlorn condition. The pitiful sight deeply excited the generous sympathies of the kind-hearted Joseph, who did what he could to comfort them by dividing his own supplies with them. General Arnold now returned with his troops to Montreal, exercising great vigilance to avoid further surprise. He then crossed the St. Lawrence and encamped at St. Johns. Here the small-pox appeared in camp. In order to avoid the severity of the disease, Joseph procured the necessary virus and inoculated himself with the point of a needle, which produced the desired effect. Two days after the disease had appeared in camp, the troops were ordered to Chambly. The British hove in sight and began to land on the opposite side of the bay. The invalids were numerous and continued to increase. They were directed to march back to St. Johns,--a distance of twelve miles. Most of them could hardly carry gun, cartridge-box, and blanket, and were often obliged to sit down and rest by the wayside, Joseph among the rest. In the course of a few days the sick were transported to Isle aux Noix, at which place all the shattered army were collected under command of General Heath. From this place the troops, including the sick, proceeded amid sundry embarrassments to Crown Point, where they encamped. Here the small-pox spread among the men, and in its most aggravated form, with fearful rapidity. The scene in camp soon became appalling. The groans and cries of the sick and dying were heard night and day without cessation. As it happened, the surgeons, for want of medicines and hospital stores, could render but little aid. In some instances as many as thirty patients died in a day, and were buried in a single vault or pit, for the reason that there were not well men enough to bury them in separate graves. The humane and philanthropic Joseph, who had previously inoculated himself with success, and thus avoided further danger from the contagion, now devoted himself to nursing and caring for his sick companions-in-arms with unwearied assiduity. As soon as the contagion began to abate, the sick were transferred in boats to Fort George, while the men fit for service were ordered to Mount Independence, opposite Ticonderoga, to erect works of defence. The mount was covered with forest trees, loose rocks, and dens infested with rattlesnakes, which often crept into camp and were killed.
