On we went, till we saw before us what we had so long been looking for,--a gentle slope which it would be easy to descend, while on the opposite side the ground was equally favourable for again ascending to the same elevation as before.  Putting the drag on the wheel, we commenced the undertaking; and though I more than once feared that the waggon would be upset, we reached the bottom in safety.  Then, immediately unyoking the tired oxen, we hurried to the fountain-head to obtain water, while they rushed to a pool close below it, where they could more easily drink.  Near at hand was an abundance of fresh grass, with which they quickly recruited their strength.
