"Is the glass falling? I am ashamed to say I have not looked at it for the past twenty-four hours. It has stuck so long at the same point that I have quite ceased to look at it two or three times a day as I usually do."

"It has not fallen much, but it is sinking."

The captain got up from the table, and went to look at the glass.

"You are right, it has fallen a good eighth; but that may mean a change of wind. Did you notice any change, Mr. Prendergast?"

"No, I can't say that I did. I looked up, as a sailor always does, when I was on deck this morning, but it was clear enough then, and I have not noticed it particularly since."

But when they went up on deck half an hour later both agreed that the mate was right. The change overhead was slight, but away to the west a dull reddish mist seemed to obscure the horizon.

"We will get the upper sails off at once, Mr. Johnson. These storms come so suddenly off the coast that it is as well to lose no time in shortening sail when one sees any indication of such a change."

The mate at once gave the necessary orders. The sailors started up with looks of surprise.

"Look sharp, men!" the mate said. "We shall have wind, and plenty of it. It will be here before long."

The men, who were by no means sorry for a spell of work after going so long without shifting sail or tack, worked hard, and the white sheets of canvas were soon snugly furled. By this time all the sailors who had been to sea for any time recognized the utility of their work. The low bank had risen and extended the whole width of the western horizon.
