Morrison fell ill and returned to Macau on 1 June 1808. Fortunately he had mastered Mandarin and Cantonese during this period. Morrison was miserably housed at Macau. It was with difficulty he induced anyone to take him in. He paid an exorbitant price for a miserable top-floor room, and had not been long in it before the roof fell in with a crash. Even then he would have stayed on, when some sort of covering had been patched up, but his landlord raised his rent by one-third, and he was forced to go out again into the streets. Still he struggled on, laboring at his Chinese dictionary, and even in his private prayers pouring out his soul to God in broken Chinese, that he might master the native tongue. So much of a recluse had he become, through fear of being ordered away by the authorities, that his health greatly suffered, and he could only walk across his narrow room with difficulty. But he toiled on.
