The year 1907 and the initials RFJ (for Gamble's caretaker, Rollie F. Johnson) are inscribed on two brick artesian wells located on the property. It can be surmised, therefore, that by that date Gamble had completed construction of a Cracker-style bungalow retreat and refurbished the old shack for use as a citrus packing barn. He named his backwoods getaway Egwanulti, a Native-American word meaning "by the water."
For years Egwanulti served as Gamble's country retreat; however, visits were usually limited to day trips rather than overnight stays. He would often invite important businessmen and dignitaries from his home state of Ohio including President William H. Taft, H.J. Heintz, and J.D. Rockefeller who would be entertained by colorful caretaker and outdoor guide, Rollie Johnson. The visitors would hunt and fish during the day and play cards in the evening before returning to their Daytona Beach lodgings.
