"It's rather steep," said Elsie, giving Andrew a sympathetic glance. "Here's a nice flat stone; we'll rest for a few minutes."
She sat down on a slab of lichened granite, and Dick found a place beside her.
"I wonder why Andrew loaded himself up with that heavy ruck-sack on a day like this?" he said. "I suppose there's a pair of marine glasses and a chart, and a parallel rule and compass, inside of it. Andrew thinks he'd get lost if he didn't carry the lot about when he risks himself ashore."
"They're all there," Andrew replied somewhat grimly. "Still, it wasn't the bag that stopped me."
"I'm sorry we forced the pace," Elsie said. "You were going well at the bottom."
"I felt all right; but that's just when my weakness finds me out. Sometimes it's the damp that brings it on and sometimes the heat; but one oughtn't to grumble about not being able to climb a hill as fast as usual." He broke off and resumed after a twinge of pain: "It's thinking of our boys being rolled back on Cambrai while I loaf about the Solway shore, that worries me."
When they had rested a while they climbed up the steep face of a pointed knoll, and then followed a long ridge to the massive cairn on the top of the hill, where shallow pools gleamed among the green moss of a bog. Andrew sat down on a stone, but Whitney stood on the highest hillock, his eyes wandering across the wide landscape that rolled away beneath him.
To the south the sea glittered like silver, and a bright arm wound inland up a valley. To the west and north a few lemon-yellow harvest fields and strips of green pasture checkered the red heath, and the smoke of a little town hung about a hollow; but the picture's dominant tone was wild solitude. The plain rose in step-like ridges, the hillsides that bordered it were washed with shades of delicate gray, and in the distance lofty rounded summits cut against the sky.
"It looks as lonely as our Western deserts," Whitney remarked.
Andrew was busy with his chart. He had spread it on a flat stone; then, putting a compass on the middle of it, he moved a notched brass ring round the instrument. The tide was about half ebb and broad belts of sand rose among the glistering channels in the firth. Andrew took sights across them, then penciled notes on the margin of the chart, but at times he lay still for a minute or two with the marine glasses at his eyes. The others left him alone until he rolled up the chart and lighted his pipe.
