At this time Joseph suffered for want of the clothes he had lost in the retreat from Canada, and had, in fact, worn the only shirt he had for six weeks, and was so incommoded with vermin that he was compelled to take off his shirt, wash it without soap, wring it out, and put it on wet. He was also scourged with an irritating cutaneous disease, which induced him to retire some distance from camp, fire a log-heap, and roast himself, after anointing with a mixture of grease and brimstone. The camp was destitute of indispensable conveniences, and the hospital in which lay the sick had not a dish of any kind in which could be administered a sup of gruel, broth, or a drink of water. Resort was had to wooden troughs, or dishes, cut out with a hatchet or penknife. The colonel, in passing through the hospital, said, "I wish there was a man to be found here who can turn wooden dishes." Joseph, who understood the art, replied, "Furnish me the tools and I will do it." The tools were furnished, and Joseph soon turned from the aspen poplar an ample supply of wooden cups and trenchers. He was also often employed in making bread, and in fact was a sort of universal genius and could do almost anything. At the instance of General Washington he was also employed at times to aid in negotiating treaties of friendship with the Indians. But after being transferred several times from one military point to another, and suffering more or less from hardships, his health became so impaired that the principal surgeon gave him a discharge, and he returned to his home in Massachusetts. He soon afterward so far recovered that he re-enlisted and served as an orderly sergeant in defence of the seaport towns till the 1st of January, 1778, when his time expired, and he returned to his father's house once more, having been in the service a little more than three years. He received, on retiring from the army, about two hundred dollars in paper currency, which was so depreciated that he could not purchase with the whole of it a decent coat. He then (for the next six months) engaged in the business of weaving on shares, and during that time wove sixteen hundred yards of plain cloth. This enabled him to clothe himself decently, and to spend the ensuing winter in improving his education. At this time, as he said, he "had no Christian hope," but continued to labor and study during the year 1779, when a religious revival occurred, and he acquired a Christian hope, with a determination to fit himself for the ministry. Encouraged by his friend, Rev. Mr. Day, he prosecuted the requisite preliminary studies, and at the same time taught a family school in order to meet his expenses. He entered college in 1781, and graduated in 1785. He then studied theology, and was licensed to preach in 1786. He soon received a call and was ordained as pastor of the church at Blandford, Mass. He had previously married Miss Lois Noble, who was a young lady of refinement and exemplary piety.
