We started again, at dark, and before long came to a railway, which, according to our map, was the line which runs parallel to the river Ems.  We knew we were coming near the Ems, and at the thought of it, drew a long breath.  It seemed a long time since we had stood on its bank before and heard the sounds from across the Holland border.  We kept going all night, avoiding the roads, and about three o’clock reached the river.  There it was!—­a much smaller river than when we had last seen it, but plenty large enough yet to fill us with apprehension.  We found a good hiding-place before daylight, and then went back to a potato-field we had passed, and put about a pailful in our sacks before settling down for the day in the wood.

Just before dawn we made our fire and roasted the potatoes.  They tasted fine, and as the day was warm and bright, we began to feel more cheerful.  That day we heard the deep-booming whistles of steamboats, and the shriller notes of the canal-boats.  Although we knew the river boats were passing up and down just below us, we restrained our curiosity and stayed closely hidden.

Just before it got dark we crept to the edge of the high ground overlooking the river.  The other side of the river was flat, and seemed to be settled.  I knew from a map I had seen that there was a canal a short distance beyond the river, and that it, too, would have to be crossed.

Looking down to the water’s edge, we saw a fence enclosing some pasture land, and were glad to see another gate, for we wanted a raft for our clothes, and we thought this would do.  It was a heavy brute of a gate.  We could hardly launch it.  Perhaps we were getting weaker—­that may have been the reason it seemed so heavy.  Anyway, when we got it to the water’s edge, we had to rest before undertaking to swim the river.  The current was not so strong as we had feared, and we reached the other side in safety.

We did not pull up the gate, but let it go drifting down the stream.  Perhaps this also is accounted for by the fact that we were getting weaker:  also, we considered that we were harder pressed for time than the German farmer—­he could make another gate.

After we had dressed and had walked for about an hour, we came to the canal.  Unfortunately for our purpose, the night was clear and the stars were out in thousands, and, to make matters worse, the young moon, just a crescent, but still capable of giving some light, came out.  We had been longer than we expected on our journey, and now, at the most critical time of it, when there was the greatest need of caution, we had moonlight nights to face!  Still, every night was getting worse than the last, so we must go forward with all speed.

The canal was about sixty feet wide, and I felt certain it would be guarded, for it was so near the border.  We went to the edge, and looked across—­and then up and down—­to see if we could find any trace of a guard; everything was quiet.
