"So, if the lightning strikes the tent, we'll all be blown up!" exclaimed Harry. "This is getting more and more pleasant."

The boys were not yet at the end of their troubles. The rain had loosened the earth, and the tent-pins, of which only four had been used, could no longer hold the tent. So, while they were talking about the powder, the tent suddenly blew down, upsetting the boys as it fell, and burying them under the wet canvas.

"Lie still, fellows," said Tom, as the other boys tried to wriggle out from under the tent. "We've got to get wet now, anyway; but perhaps, if we stay as we are, we can manage to keep the blankets dry."

The wet tent felt miserably cold as it clung to their heads and shoulders, but the boys kept under it, and held their blankets and spare shirts wrapped tightly in their arms. Luckily the storm was nearly at an end when the tent blew down, and a few moments later the rain ceased, and the crew of the Whitewing, in a very damp condition, crept out and congratulated themselves that they had escaped with no worse injury than a wet skin.

"Where are the rubber blankets?" asked Harry.

"Rolled up with the other blankets," answered everybody.

"It won't do to tell when we get home," remarked Harry, "that instead of using the water-proof blankets to keep ourselves dry, we used ourselves to keep the water-proofs dry. It's the most stupid thing we've done yet; and I'm as bad as anybody else."

"It was a good deal worse to pitch a tent without digging a trench around it," said Tom. "If I'd dug a trench two inches deep just back of that tent, not a drop of water would have run into it."

"And I don't think much of the plan of using only four pins to hold a tent down when a hurricane is coming on," said Joe.
