The volleys from the Mexicans ceased, and silence came again in the woods.  Wisps of smoke floated here and there among the trees, but a light wind soon caught them and carried them away.  Ned and Obed, rolling into easier positions, talked cheerfully.

“I don’t think they’ll try to rush us,” said Obed.  “The Mexicans are not afraid to charge breastworks, but they’ll hardly think we two are worth the price they would have to pay.  Perhaps they’ll try to starve us out.”

“And that they can’t do because we have provisions for several days.”

“But they don’t know it.  Nor do we want to stay here for several days, Ned.  Texas is calling to us, and we should be traveling northward instead of lying under a rock besieged by Mexicans.”

But they were compelled anew to make heavy drafts upon their patience.  The Mexicans kept quiet a long time.  Finally a shot fired from some high point grazed Ned’s cap, and flattened against the rock behind him.  The boy involuntarily ducked against the earth.  Obed also lay lower.

“Some Mexican must have climbed a tree,” said the Maine man.  “He’s where he can look over our fortifications and that gives him an advantage.  It also gives him a disadvantage because it will be harder for him to come down out of that tree unaided than it was for him to go up in it.  We’ll stick as close as we can under the log, until he sends in the second shot.”

They waited about ten minutes until the Mexican fired again.  He was in the boughs of a great oak about fifty yards away, and following the flash of his weapon they saw his chest and shoulders as he leaned forward to take aim and pull the trigger.  Obed fired and the soldier dropped to the ground.  There was a noise in the underbrush, as if his comrades were dragging him away and then the great silence came again.  As Obed reloaded he said grimly: 

“I think we’re done with the tree-climbers.  Evil to him who evil does.  They’re cured of that habit.”

It was now mid-afternoon and the sun was blazing down over the cliffs and forest.  It grew very hot in the alcove.  No breath of wind reached them there, and they began to pant for air.

“I hope night will come soon,” said Ned.

“It will be here before long,” said Obed, “but something else will arrive first.”

“What is that?”

“Look, there to the right over the trees.  See the dark spot in the sky.  Ned, my boy, a storm is coming and it is for you and me to say ’let it come.’”

“What will it do for us?”

“Break up the siege, or at least I think so.  Unless it drives directly in our faces we will be sheltered out here, but the Mexicans will have no such protection.  And, Ned, if you will listen to one who knows, you will understand that storms down here can be terrific.”

“Then the more terrific it is the better for us.”

“Just so.  See, Ned, how that black spot grows!  It is a cloud of quite respectable size.  Before long it will cover all the skies, and you notice too that there is absolutely no wind.”
