No birds were counted which were able to scramble into the water and swim off: only those which were dead or too sick to travel were enumerated. Two men generally conducted the count,---one to call off the names of the birds, the other to tabulate them. Of course it was impossible to estimate the number of dead birds on the lake from the numbers on the levees alone, because, in the first place, more birds died on the levees than elsewhere, the sick and well both making an effort to attain these resting places during the day; and, secondly, the strong north winds blew the carcasses of those dying on the water southward against the levees. In near- ly every case there were more dead birds on the north and west sides of the levees
