Journey

Roberts sailed away from England in September 1887 on the s.s. Glenshiel. He was accompanied by several veteran missionaries on the ship, and he used his time at sea to study the Bible and Chinese. His ship arrived in Shanghai, China, where he and the other missionaries assigned to Tientsin rested for several days. From Shanghai, Roberts' group traveled north by land to the London Missionary Society settlement in Tientsin.^[2]

Tientsin

In Tientsin, Roberts resided with the London Missionary Society medical missionary stationed there, John Kenneth Mackenzie. Working alongside Dr. Mackenzie at the Tientsin Mission Hospital and Dispensary (later Mackenzie Memorial Hospital), he gained experience speaking Chinese, working in a Chinese hospital, and evangelizing with patients and medical students.^[5][6] He also taught in the medical school established by Dr. Mackenzie, which was the first medical school in China to teach Western medicine.^[7] When Dr. Mackenzie left the mission to treat patients in the countryside for several weeks, Roberts was put in charge of teaching surgery to the Chinese medical students. In March 1888, Mackenzie decided that Roberts was ready to help Gilmour in Mongolia.^[2]

Mongolia

Roberts made the journey to Mongolia with only a servant and a mule-drawn cart.^[8] His arrival was highly anticipated by Gilmour, who had no formal medical training. Roberts and Gilmour traveled between the London Missionary Society's three missions in the Mongolian countryside, remaining at each one for a few days. Roberts was involved with both medical work and sharing Christianity among the people. He also set aside time each morning to study Chinese.^[2]

Return to Tientsin

A few weeks into his service with Gilmour, Roberts was informed that Dr. Mackenzie had fallen ill and died. Roberts was then asked by the London Missionary Society to return to Tientsin to take over operations of the mission hospital.^[8] He was conflicted over leaving Gilmour alone, but he believed it was God's will for him to accept the position. Roberts did not further delay his return to Tientsin, making most of the journey by sea.

Following Mackenzie's death, Viceroy Li withdrew government support of the Tientsin hospital, which led to many of the workers leaving. This left Roberts without qualified assistants, so he did all the medical work in the hospital on his own. Aversion to mattresses and eating while sick, unsanitary conditions in Tientsin, and an initial sentiment of only utilizing foreign doctors as a last resort were other obstacles that Roberts had to contend with in Tientsin.

Roberts incorporated Christianity into the care of all of his patients, suggesting that they pray or give thanks to God. He often lamented that he could not spend more time evangelizing due to his heavy patient load. Seeking to increase missionary work among the local women, he wrote to his sister Mary asking her to join him.^[2] She arrived in Tientsin in November 1888.^[3]

By the end of 1888, Roberts had treated over 11,000 patients and 400 outpatients. These numbers increased to 18,000 and 900 in 1890 and continued to increase as his fame spread throughout Northern China. Most of his initial patients were poor, but wealthy patients started coming to his hospital after hearing about his excellent care. Some patients would travel 200 miles to receive care under Dr. Roberts. The hospital was then constantly filled to capacity.

All of Roberts' medical services were free of charge, and he would use his salary from the London Missionary Society to support the hospital's expenses. Cataracts, cholera, and dysentery were the most common conditions he treated.^[2] In addition to his treatment and evangelism efforts, Roberts also collected data on dysentery for a thesis he was preparing and was active in the Medical Missionary Association of China.^[9]

Dr. G.P. Smith, who Roberts had met at Edinburgh, was appointed to assist him in 1892.^[1] Having another doctor in Tientsin allowed Roberts to dedicate more time to the evangelism of the people of Tientsin.^[8]

Rural Work and Famine Relief

Following floods in 1890 and 1893, many of the Chinese living in the Northern China countryside lost their homes and sources of food. Roberts recognized that little of the funds distributed by the Chinese Government for relief made it to the suffering people. To help remedy this, he and fellow missionary Rev. Thomas Bryson traveled to affected villages after the floods to provide the people with money to sustain themselves through the cold season.

After the arrival of Dr. Smith in 1892, Roberts and his sister travelled 100 miles southwest to the villages of the Yen Shan district to provide medical care and evangelize among the people. Crowds flocked to Roberts for medical care, and he was constantly invited into people's homes. His days in the countryside typically involved seeing patients all day and then sharing Christianity in the evenings. Roberts treated 1,500 patients and performed 20 operations while in Yen Shan.

Roberts traveled back to Yen Shan with his sister in 1894 on a similar mission.^[2]

Death

When Roberts returned from his second Yen-Shan circuit in the spring of 1894, Dr. Smith was recovering from influenza. Roberts sent Smith away from Tientsin so that he could regain his strength before the summer began.^[2] In May 1894 Roberts caught a sudden fever and died a few days later.^[3] It is believed he was weakened by the burden of having to manage the hospital on his own.^[2]
