Some Recent Experiments with Dynamite on an Ocean Bar
During the months of July and August, 1891, some experiments were made by a committee of the Board of Trade of Brunswick, Ga., with a view to temporarily increasing the depth of water over the ocean bar at the entrance to that harbor. The inner harbor, with depths in 1880 of only 9 feet at mean low water, has been improved under the direction of the United States Engineer Department until there now exists a minimum low-water channel depth of 15 feet. The outer harbor, which comprises the anchorages in Brunswick River and St. Simon's Sound, has ample depths for all classes of vessels. The entrance to the harbor is, however, obstructed by the ocean bar, which extends in a horse-shoe shape from St. Simon's Island on the north to Jekyl Island on the south. The bar has not changed much in location or in general direction within the last thirty-five years or since the date of the earliest authentic survey, but the channel across it has shoaled during that period. The mean low-water channel depth, which, in 1856, was 15 feet, was found by the survey of 1890-91 to be, in places, not more than 13.2 feet.
