By this time one of the rollers would come out behind, and Marco would take it up and carry it round forward, and place it under the bow, and Forester would then say, "_Ahead with her!_" again, and the boat would immediately advance again up the acclivity.
[Illustration: THE PORTAGE.] In a very few minutes the boat was thus rolled up into a sort of a road, where the way was level.

Here it went very easily.

Presently it began to descend, and soon the boys saw that Forester was taking a sort of path which led by a gentle slope down to the water immediately below the mill.

They were very much pleased at this, for, as they had had a great many excursions already on the mill-pond, they had become familiar with it in all its parts, and they were much animated at the idea of exploring new regions.

In going down to the water on the lower side of the mill, they had, of course, no exertion to make to draw the boat, as its own weight was more than sufficient to carry it down upon the rollers.
