"How long will it be before we have water enough to cross the Spit?"
Lionel asked as they laid in the oars.
"Well nigh four hours, Master Lionel. Then, even if it keeps a stark calm like this, we shall be able to get across the sands and a mile or two up the channel before we meet the tide. There we must anchor again till the first strength is past, and then if the wind springs up we can work along at the edge of the sands against it. There is no tide close in to the sands after the first two hours. But I still think this is going to turn into wind presently; and if it does it will be sharp and heavy, I warrant. It's either that or rain."
The sky grew darker and darker until the water looked almost black under a leaden canopy.
"I wish we were back into Bricklesey," Joe Chambers said. "I have been well-nigh fifteen years going backwards and forwards here, and I do not know that ever I saw an awkwarder look about the sky. It reminds me of what I have heard men who have sailed to the Indies say they have seen there before a hurricane breaks. If it was not that we saw the clouds flying fast overhead when we started, I should have said it was a thick sea fog that had rolled in upon us. Ah, there is the first drop. I don't care how hard it comes down so that there is not wind at the tail of it. A squall of wind before rain is soon over; but when it follows rain you will soon have your sails close-reefed. You had best go below or you will be wet through in a minute."
The great drops were pattering down on the deck and causing splashes as of ink on the surface of the oily-looking water. Another half minute it was pouring with such a mighty roar on the deck that the boys below needed to shout to make each other heard. It lasted but five minutes, and then stopped as suddenly as it began. The lads at once returned to the deck.
"So it is all over, Master Chambers."
"Well the first part is over, but that is only a sort of a beginning. Look at that light under the clouds away to the south of east. That is where it is coming from, unless I am mistaken. Turn to and get the mainsail down, lads," for although after dropping anchor the head sails had been lowered, the main and mizzen were still on her.
The men set to work, and the boys helped to stow the sail and fasten it with the tiers. Suddenly there was a sharp puff of wind. It lasted a few seconds only, then Joe Chambers pointed towards the spot whence a hazy light seemed to come.
"Here it comes," he said. "Do you see that line of white water. That is a squall and no mistake. I am glad we are not under sail."
There was a sharp, hissing sound as the line of white water approached them, and then the squall struck them with such force and fury that the lads instinctively grasped at the shrouds. The mizzen had brought the craft in a moment head-to-wind, and Joe Chambers and the two sailors at once lowered it and stowed it away.
