After continuing in the practice a few years, and his health seeming to be restored, he ventured to return again to the work dearer to him than any other—that of teaching. But his labors seemed again to be slowly undermining his health, and, fearful of a relapse of the pulmonary tendencies, he abandoned for a time all hope of teaching permanently.
The following year, he became connected with Rev. William C. Woodbridge, and continued to labor in the cause of education for several successive years.
In Jan. 1833, he removed to Boston, and during the winter had a severe attack of bleeding at the lungs, and other dangerous symptoms. These, however, passed away; and the great change which, in 1830, had been made in his physical habits, seemed to be working one equally great in his constitutional tendencies. For while his labors were constant and often severe, there was a steady gain in health. The strength and elasticity of youth returned, and, to use his own words it was with him, now, "morning all day." The effects of an unfavorable climate, which he had feared, were apparently held in check, and he sometimes said that "Obedience gave him command over climate, in a great degree." Yet, during all these years when his health was apparently most firm, it was kept in this condition only by a rigid obedience to the laws of life and health, as he understood and expounded them. His precepts and practice were in harmony.
In the spring of 1848, owing to some unusual exposure, a return of the cough and other symptoms of his old disease made their appearance.[N] But, with care, and light labor in the garden, they gradually passed away, and his usual measure of health returned, and continued, with slight interruptions, till 1855. During this year he was confined to his room several months with a broken limb. The change, at his age, from exercise daily in the open air, to confinement without exercise nearly all winter, was very unfavorable, in its results, to his general health. The lungs, doubtless, suffered greatly, and were never able to resist, as before, the effects of exposure to sudden changes of temperature.
Still he labored on from year to year, untiringly as ever, writing, lecturing, visiting schools, etc. During the last winter, his time was employed more exclusively in reading and writing, and he went out less than usual. His lungs were weak and very easily affected. A difficulty of breathing after much exertion was frequent. His feet and ankles were often much swollen, and there was a loss of strength and general debility quite new to him.
These indications were not to be mistaken, and in the retirement of his own home he often spoke of the possibility and even probability, that his earthly labors were drawing to a close.
On the 18th of March, he left home to be absent a few days, partly with the hope that being more in the open air might prove beneficial. On Friday of the following week, though scarcely able to be moved, he was brought home, having been prostrated by what appeared to be a violent attack of pleurisy, which terminated his earthly existence, on Tuesday, March 28, 1859.
In many minds the question will naturally arise: What should induce such an apparently violent disease, in a person who so rigidly obeyed the laws of health? A satisfactory answer to this can be given only by supposing the acute disease to have been merely a finishing up or termination of that disease which for years had been held in check. His own views on the subject were in accordance with this conclusion, and the condition of the lungs, as shown by a post mortem examination, served to confirm it. The amount of disease found in the lungs was so great that the examination could not be as careful and satisfactory as would have been desirable.
The hand that wrote this volume, and that would have drawn important lessons from this page of life, now moulders in the dust. To the reader it is left to gather from it instruction and motive and courage, for a like battle against evil, for a like victory over self, until he, too, shall accomplish his mission upon earth.
