Added to these and other perplexities was the ever-present question of finance. The rapid growth of the movement caused a requirement of funds far beyond the revenue of the Association. Its income came mainly from the gate-fees, to which was added a small tax upon each lot, and the concessions to store-keepers; for the prices obtained by the leasing of new lots must be held as a sinking fund to pay off the mortgages incurred in their purchase. There came also an imperative demand for a water-supply through an aqueduct, a sewer-system, and other sanitary arrangements made absolutely necessary by the increase of population. In those years Mr. Miller's purse was constantly opened to meet pressing needs, and his credit enabled the trustees to obtain loans and mortgages. But despite his multitudinous cares and burdens, no one ever saw Mr. Miller harassed or nervous. He was always unruffled, always pleasant, even smiling under the most trying conditions. His head was always clear, his insight into the needs not only of the time but of the future also was always sure, and his spinal column was strong enough to stand firm against the heaviest pressure. He knew instinctively when it was wise to conciliate, and when it was essential to be positive. The present generation of Chautauquans can never realize how great is their debt of gratitude to Lewis Miller. The inventor and manufacturer of harvesting machines at Akron and Canton, Ohio, busy at his desk for eleven months, found the Swiss Cottage beside Chautauqua Lake by no means a place of rest during his brief vacation. Nor were the burdens upon the other Founder lighter than those of his associate. The two men talked and corresponded during the year regarding the coming program, but the selection, engagement, and arrangement of the speakers was mainly Dr. Vincent's part. At the same hour, often half a dozen meetings would be held, and care must be taken not to have them in conflict in their location and their speakers. Changes in the program must often be made suddenly after a telegram from some lecturer that he could not arrive on the morrow. New features must be introduced as the demand and the opportunity arose,--the Baptists, or Methodists, or Congregationalists, or Disciples desired a meeting, for which an hour and a place must be found. The only one who kept the list of the diversified assemblages was Dr. Vincent. He had no secretary in those days to sit at a desk in an office and represent the Superintendent of Instruction. His tent at the foot of the grounds was a stage whereon entrances and exits were constant. Moreover, the audience was apt to measure the importance of a lecture by the presence of Dr. Vincent as presiding officer or a substitute in his place introducing the speaker. The Vincent temperament was less even and placid than the Miller; and the Assembly of those early years generally closed with its Superintendent in a worn-out physical condition.
