The sun was setting when Bobby, now well in the lead, halted his team at Abel Zachariah's old fishing place on Itigailit Island to await Skipper Ed and Jimmy. The sea, far out in the direction in which Abel had found Bobby in the drifting boat that August morning, was frozen, and a little way out from Itigailit Island the smooth ice gave place to mountainous ridges and hummocks where, earlier in the season, rough seas had piled massive blocks one upon another and left them there to freeze and catch the drifting snow. Far out beyond the pressure ridges Bobby could see a dark line which marked the edge of the sea ice and the place where open water began. That was the _sena_ for which they were bound.
