"If we're going to do that, we must be quick about it, for it's going to rain in a very few minutes," said Charley. "I guess it's the best thing we can do, though this isn't the best anchorage in the world. Come, Joe, you and I will roll up the sails, while the other fellows rig up the canvas. We've got to make things pretty snug, for it may blow hard."

The sails were quickly furled, and Tom and Harry had the canvas cabin ready just as the first drops of rain began to fall. The boys crept under the canvas, congratulating themselves that they had a secure shelter, and that they had noticed the approach of the shower in time to prepare for it.

The wind blew very hard, and the Ghost began to pitch uneasily.

"It's a good job we've got such a lot of cable," said Charley. "When I saw that the Ghost had fifty feet of inch rope coiled up on her deck, I couldn't help laughing, and wondering if Harry expected to anchor in fifty feet of water; but, after all, a long cable is a handy thing to have, and we needn't have the least fear that we shall drag our anchor or part our cable."

"This canvas cabin works splendidly," remarked Harry. "Tom, you deserve all our thanks for inventing it. Why, it's fairly dry on the inside." So saying, Harry put the palm of his hand against the canvas over his head, and rubbed it to see if it was wet.

"Now you've done it," cried Tom. "Don't you know how a tent will leak if you touch it when it is wet? You'll have a stream of water running in here presently."

Tom was right. In a few minutes the water began to drip steadily on the unfortunate Harry, who was forced to sit with a tin pail in his lap to catch the stream that he had introduced into the cabin.

The rain was now pouring down in a perfect cataract, and the gusts of wind were trying their best to tear the canvas away. Tom felt a strong desire to look out and see how things were getting on. Accordingly, without saying anything to anybody, he quietly unfastened the opening in the after-end of the cabin, and put his head out into the rain. No sooner did the wind find an entrance into the cabin through the opening Tom had made than the canvas gave a tremendous flap, which broke the cords that held it in place; and had not Harry caught hold of it, and dragged it inside the cockpit; it would have been overboard in a second.

"Well, I never in all my life!" began the astonished Tom.

"I told you we were going to get wet," said Joe. "We always do. We got wet about three times every day in the Whitewing."
