Discussions of this nature were calculated to deepen thought and to promote heart-searching on the part of the Christian worker. They also illustrate some of the special difficulties which missionaries in China and India have to meet. With an elaborate religious ritual and literature, both Buddhist and Hindu can often, and do often, object against Christianity many of those, sometimes obvious, sometimes subtle, difficulties which the Gospel of Jesus Christ alone can remove, and which it removes by sanctifying and dominating the heart. In February 1873 Gilmour visited Tientsin for the first time since he passed through it on his arrival in China. Here he took part in several readings, temperance meetings, and religious services. At one of the readings:-- 'One joke happened. I was asked to give a recitation at a penny reading for sailors. The piece was "The Execution of Montrose." I got up in tragic style, said, "Come hither, Evan Cameron," with the appropriate beckoning action, when a sailor in the middle of the audience responded to the call, pressed his way out of the passage, and was making for the platform. I could not stand this, so I uttered a yell, and rushed off to hide myself, and it was some time before the audience and speaker could compose themselves for a fresh start Next day we were told that the unfortunate sailor was beckoned to come hither from all parts of the ship.' CHAPTER IV THE FIRST CAMPAIGN IN MONGOLIA In 1873 Gilmour resumed his visits to the Plain and on March 15 he was at Kalgan, writing, 'No appearance of getting away to the north. I promenade daily the streets and accost Mongols, but with no success as to getting camels, or even a horse to hire as far as Mahabul's. A day or two later Mahabul arrived in Kalgan on his way to Peking, and by his aid Gilmour secured two camels, and on March 24 he started north, reaching Mahabul's tent on the 28th. He at once endeavoured to secure the services of a Mongol named Lojing, and the usual series of delays and vexations occurred.
