I. The Florida Sponge Fishery .—History of the Fishery. Kinds of sponges taken. Relative value of sponges. Methods of procuring sponges. Curing the sponges. Sponge grounds reduced in value through over—fishing.

Sponge Culture Experiments.—historical.

Experiments of Buccicli. —Description of apparatus used, and manner in which the experiments were conducted. Buccich concluded that sponge cuttings would grow to marketable size in seven years.

Experiments in Florida.—Sponge cuttings said to grow more rapidly, increasing to from four to six times their original size in six months, when placed under favourable conditions.

Memorandum by Mr. Benedict, of U.S. National Museum,.—Sponge culture experiments do not appear to have been tried to any great extent. Fishermen opposed to anything of the kind as likely to lead to monopoly, and the cutting off their means of subsistence.

Would Sponge—Culture By Cuttings Be Profitable—Marenzeller points out that this would depend on whether pieces of a sponge would in a given time together attain a greater weight than the original sponge would have reached if left undisturbed.

Suggested Experiments.—Suggestions by Mr. Bidder {see below). Fishing by means of divers, or dredging, should be tried in deeper water.
