"I would just as soon try to walk through a field covered with cactus plants," he said.

"So would I," laughed Sumner, "if I had to walk as you do. In a pineapple patch you must never lift your feet, but always shuffle along. In that way you force the prickly leaves before you, and move with their grain instead of against it."

Although the crop would not be ready for cutting much before May, they found here and there a lusciously ripe yellow "pine," and after eating one of these, Worth declared that he had never before known what a pineapple was. He did not wonder that they tasted so different here and in New York, when he learned that for shipment north they must be cut at least two weeks before they are ripe, while they are hard and comparatively juiceless.

At the end of three days an outgoing tide, rushing like a mill-race, swept the canoes through the green expanse of "The Grasses," that looked like a vast submerged meadow, and into the open waters of the Bahia Honda, or, as the reef-men say, the "Bay o' Hundy." Here they first saw spongers at work, and devoted an entire day to studying their operations.

Worth had always supposed that sponges were dived for, but now he learned his mistake. He found that in those waters they are torn from the bottom and drawn to the surface by iron rakes with long curved teeth attached to slender handles from twenty to thirty feet in length. The sponging craft are small sloops or schooners, each of which tows from two to six boats behind it. When a sponge bed is discovered, two men go out in each of these boats. One of them sculls it gently along, while the other leans over the gunwale with a water-glass in his hands, and carefully examines the bottom as he is moved slowly over it. The water-glass is a common wooden bucket having a glass bottom. This is held over the side of the boat so that its bottom is a few inches below the surface of the water, or beyond the disturbing influence of ripples. With his head in this bucket, the sponger gazes intently down until he sees the round black object that he wants. Then he calls out to the sculler to stop the boat, and with the long-handled rake that lies by his side secures the prize. It is black and slimy, and full of animal matter that quickly dies, and decomposes with a most disgusting odor. To this the spongers become so accustomed that they do not mind it in the least, and fail to understand why all strangers take such pains to sail to windward of their boats.

When the deck of a sponge boat is piled high with this unsavory spoil of the sea, she is headed towards the nearest key on which her crew have established a crawl,[B] and her cargo is tossed into it. The crawl is a square pen of stakes built in the shallow water of some sheltered bay, and in it the sponges lie until their animal matter is so decomposed that it will readily separate from them. Then they are stirred with poles or trodden by the feet of the spongers until they are free from it, when they are taken from the crawl, and spread on a beach to dry and whiten in the sun. When a full cargo has been obtained, they are strung in bunches, and taken to Key West to be sold by the pound at auction. There they are trimmed, bleached again, pressed into bales, and finally shipped to New York.

Sponges are of many grades, of which the sheep's wool is the finest, and the great loggerheads the most worthless. As spongers can only work in water that is smooth, or nearly so, half their time is spent in idleness; and though they receive large prices for what they catch, the average of their wages is low.

One hot afternoon at the end of a week found our canoemates half-way up the reef, and approaching a key called Lignum Vitæ, which is for several reasons one of the most remarkable of all the keys. It is a large island lifted higher above the surface of the water than any of the other keys, and it contains in its centre a small fresh-water lake. It is covered with an almost impenetrable forest growth, and concealed by this are ancient stone walls, of which no one knows the origin or date.

Sumner had told Worth so much concerning this key as to arouse his curiosity, and they both looked forward with interest to reaching it. All day they had seen it looming before them, and when they finally dropped sail close beside it, Worth proposed that they take advantage of the remaining daylight to make a short exploration before unloading their canoes and pitching camp. To this Sumner agreed, and as they could not drag the laden boats up over the rocky beach, they decided to anchor them out and wade ashore. So the Psyche's anchor was flung out into the channel, the Cupid was made fast to her, and a light line from its stern was carried ashore and tied to a tree. Then, taking their guns with them, the boys plunged into the forest.
