I found this gull abundant about the large pond behind the town 

 at Petropaulski, and it was occasionally seen about the inner harbor.

 Just as we were entering the Seymour Narrows we saw a large flock

 following the ship all the time until we reached the vicinity of the 

 Columbia River, where they disappeared. We met them again about 

 half an hour after Leaving the channel between Vancouver Island 

 and the mainland. Here they were very common, becoming more
