"It becomes every man who purposes to give himself to the care of others, seriously to consider the four following things: _First_, That he must one day give an account to the Supreme Judge of all the lives intrusted to his care. _Secondly_, That all his skill and knowledge and energy, as they have been given him by God, so they should be exercised for his glory and the good of mankind, and not for mere gain or ambition. _Thirdly_, and not more beautifully than truly, Let him reflect that he has undertaken the care of no mean creature, for, in order that we may estimate the value, the greatness of the human race, the only begotten Son of God became himself a man, and thus ennobled it with his divine dignity, and, far more than this, died to redeem it; and _Fourthly_, That the Doctor, being himself a mortal man, should be diligent and tender in relieving his suffering patients, inasmuch as he himself must one day be a like sufferer." I shall never forget a proof I myself got twenty years ago, how serious a thing it is to be a doctor, and how terribly in earnest people are when they want him. It was when cholera first came here in 1832. I was in England at Chatham, which you all know is a great place for ships and sailors. This fell disease comes on generally in the night; as the Bible says, "it walks in darkness," and many a morning was I roused at two o'clock to go and see its sudden victims, for then is its hour and power. One morning a sailor came to say I must go three miles down the river to a village where it had broken out with great fury. Off I set. We rowed in silence down the dark river, passing the huge hulks, and hearing the restless convicts turning in their beds in their chains. The men rowed with all their might: they had too many dying or dead at home to have the heart to speak to me. We got near the place; it was very dark, but I saw a crowd of men and women on the shore, at the landing-place. They were all shouting for the Doctor; the shrill cries of the women, and the deep voices of the men coming across the water to me. We were near the shore, when I saw a big old man, his hat off, his hair gray, his head bald; he said nothing, but turning them all off with his arm, he plunged into the sea, and before I knew where I was, he had me in his arms. I was helpless as an infant. He waded out with me, carrying me high up in his left arm, and with his right levelling every man or woman who stood in his way. It was Big Joe carrying me to see his grandson, little Joe; and he bore me off to the poor convulsed boy, and dared me to leave him till he was better. He did get better, but Big Joe was dead that night. He had the disease on him when he carried me away from the boat, but his heart was set upon his boy. I never can forget that night, and how important a thing it was to be able to relieve suffering, and how much Old Joe was in earnest about having the Doctor.
