The first structure to be built on this uninhabited oceanfront was the Biscayne House of Refuge, constructed in 1876 by the United States Life-Saving Service through an executive order issued by President Ulysses S. Grant, at approximately 72nd Street. Its purpose was to provide food, water, and a return to civilization for people who were shipwrecked. The structure, which had fallen into disuse by the time the Life-Saving Service became the U.S. Coast Guard in 1915, was destroyed in the 1926 Miami Hurricane and never rebuilt. The next step in the development of the future Miami Beach was the planting of a coconut plantation along the shore in the 1880s by New Jersey entrepreneurs Ezra Osborn and Elnathan T. Field, but this was a failed venture. One of the investors in the project was agriculturist John S. Collins, who achieved success by buying out other partners and planting different crops, notably avocados, on the land that would later become Miami Beach. In fact, the pine trees on today's Pinetree Drive served as an erosion buffer for Collins' plantations. Meanwhile, across Biscayne Bay, the City of Miami was established in 1896 with the arrival of the railroad and developed further as a port when the shipping channel of Government Cut was created in 1905, cutting off Fisher Island from the south end of the Miami Beach peninsula. Collins' family members saw the potential in developing the beach as a resort. This effort got underway in the early years of the 20th century by the Collins/Pancoast family, the Lummus brothers (bankers from Miami) and Indianapolis entrepreneur Carl G. Fisher. Until then, the beach here was only the destination for day-trips by ferry from Miami, across the bay. By 1912, Collins and Pancoast were working together to clear the land, plant crops, supervise the construction of canals to get their avocado crop to market and set up the Miami Beach Improvement Company. There were bathhouses and food stands, but no hotel until Brown's Hotel was built in 1915 (still standing, at 112 Ocean Drive). Much of the interior landmass at that time was a tangled jungle of mangroves. Clearing it, deepening the channels and water bodies, and eliminating native growth almost everywhere in favor of landfill for development, was expensive. Once a 1600-acre, jungle-matted sand bar three miles out in the Atlantic, it grew to 2,800 acres when dredging and filling operations were
