"I am driven in spite of myself, to do more than I know I can well stand . . . If I could multiply myself into a hundred bodies, each with the strength of a Hercules, and the mental and moral energy of a Paul, I could not overtake the calls and demands made on me here, and from many other quarters since my arrival . . . All very delightful, if I had the needful strength. But no strength of any man that ever lived would stand out all this . . . As regards this place I have abundant satisfaction in already knowing that I have not come here in vain." No, indeed, Dr. Duff had not come to the West in vain, his labours bore rich and varied fruit. When he embarked again for home, a letter was put into his hand containing £3000, or at least 30,000 rupees for the missionary cause from New York and Philadelphia. Canada also gave her cheerful aid, and this though Dr. Duff "had nowhere pleaded for money," and had only spoken of his own special work in India when pressed to do so at social meetings. Nor were large subscriptions from various quarters all the results of that memorable visit; American love for missions had been stirred up to a blaze which has never since died out. The United States still give some of their noblest sons and daughters to work for the Lord in India, side by side with their brethren and sisters from England and Scotland. On the morning of his embarkation, Dr. Duff preached for the last time in America to multitudes assembled to see him depart. With a loving grateful heart he gave the people his solemn blessing, and all the congregation rose to receive it. Then leaving the pulpit, and making his way through crowds who pressed forward to have one more grasp of his hand, the Missionary passed on to the steamer. "There," wrote an eye-witness, "the scene defied description. The wharf and the noble 'Pacific' were crowded with Christians assembled to bid him farewell. Many could only take him by the hand, weep and pass on. Never did any man leave our shores so encompassed with Christian sympathy and affection." Dr. Duff's visit to America had been a glorious success, but a heavy price was to be paid for it by the exhausted Missionary. After his return home, Dr. Duff became fearfully ill. Congestion of the brain, followed by utter prostration of the over-worked mind, made the once powerful and talented man helpless as a little child. It was a cause of deep thankfulness, after a long space of time had elapsed, to find that the grand mind was not permanently impaired, that the brain was recovering its power. ———————— CHAPTER XIII. IN INDIA AGAIN. Long as it was before the invalid regained the power to work, with that power came the renewed desire to labour in India. Dr. Duff never forgot that beloved land. How the Missionary felt may be shown by part of a letter written in 1853, before his last severe illness, to one of the Indian converts.
