When they were rested, they visited a copper-mine by the side of the head, and filled their pockets with bits of bright quartz or red shining spar, which they found in plenty among the rocks.
In the afternoon they strolled towards home, determining to stop a little at the Stack on their way.

The Stack formed one of the extremities of Ellan Bay, and was a huge mass of isolated schist, accessible at low water, but entirely surrounded at high tide.

It was a very favorite resort of Eric's, as the coast all about it was bold and romantic; and he often went there with Russell on a Sunday evening to watch the long line of golden radiance slanting to them over the water from the setting sun--a sight which they often agreed to consider one of the most peaceful and mysteriously beautiful in nature.
They reached the Stack, and began to climb to its summit.

The sun was just preparing to set, and the west was gorgeous with red and gold.
"We shan't see the line on the waters this evening," said Eric; "there's too much of a breeze.

But look, what a glorious sunset!" "Yes; it'll be stormy tomorrow," answered Russell, "but come along, let's get to the top; the wind's rising, and the waves will be rather grand." "Ay, we'll sit and watch them; and let's finish our grub; I've got several eggs left, and I want to get them out of my pocket." They devoured the eggs, and then stood enjoying the sight of the waves, which sometimes climbed up the rock almost to their feet, and then fell back, hissing and discomfited.
