We have thus given a memoir of Mr. Ballou's life up to the period of his settlement in Boston, where he was destined to operate upon a more extended field of action,--where his mental and physical powers, thoroughly trained and tested as they had been, were to be taxed more heavily still; and where he was destined to build for himself a name that will live in the grateful memory of future generations, and to erect for himself a monument that points further heavenward than eastern pyramids,--the savor of a truly Christian life. Immediately on his becoming settled in Boston, in addition to the duties of his pastoral charge, and that of writing for two or three religious periodicals, Mr. Ballou was obliged to answer the frequent demands that poured in upon him, from every quarter, to lecture and to preach in the numerous towns within ten, twenty, and often fifty miles of the city, at a time when the means of communication were, at best, but very indifferent,--rendering it necessary for him to drive his own vehicle, in order to reach the desired point without loss of time. So frequent and urgent were these demands for his services, in towns and villages of New England, that week-days, as well as Sundays, were occupied in holding forth to the people, who came from far and near to hear him. Not unfrequently were several consecutive days thus employed; portions of the night even being improved in travelling between the several places when at a great distance apart, and sleep, or rest of any sort, being but sparingly indulged in. But so zealous was he in the glorious cause that filled his whole soul,--so thoughtless of self, and so wedded to his Master's business,--that his own labors seemed to him as nothing; and neither his energies nor his spirits were wearied for a single moment. The bow of his mind and body both seemed ever strung and bent, yet never to lose their elasticity. The amount of actual physical labor which he thus performed can hardly be estimated; but certain it is that he must have been almost miraculously sustained, to have endured so much fatigue without most serious injury.
