"It seems to me that this is enough for one day. Before going back, however, let us look all around this place. You know the Professor will be sure to want to know everything about it."
Directly west of the knoll, on which the huts were situated, was a slight declivity. "Let us go down the hill for several hundred feet," said George, as he led the way through the tangled brush.
Within a hundred feet of the hut was a little brook, with the clearest cold water. "I can see why the huts were placed there. Look at that spring."
Within fifty feet of their position was a slightly shelving rock, and below it a bubbling spring flowing upwardly into a semicircular basin formed in the rock.
George ran forward and made a quick survey. "Here is a metal drinking cup, just as they left it. My, but it's heavy!"
"I wonder what it is made of? Here, rub it."
Only a few passes were made over it, when he held it up in astonishment. "Why, it looks like silver."
"So it does," broke in Harry. "But what is this on the side? See those initials: 'A.W.'"
"I must have a drink before I leave this," and Harry removed the little copper cup which he always carried. "What a peculiar water this is! It must be a kind of mineral water."
"Yes," responded George; "that is sulphur water, or it has considerable sulphur in it."
