The constant increase in the number of visitors, the inadequacy of accommodation in the city, and the difficulty of finding provisions for consultants, led to his introducing what he called night oracles. He received the packets, slept upon them, in his own phrase, and gave answers which the God was supposed to send him in dreams. These were generally not lucid, but ambiguous and confused, especially when he came to packets sealed with exceptional care. He did not risk tampering with these, but wrote down any words that came into his head, the results obtained corresponding well enough to his conception of the oracular. There were regular interpreters in attendance, who made considerable sums out of the recipients by expounding and unriddling these oracles. This office contributed to his revenue, the interpreters paying him £250 each.
