We shall assume that the latter offsets the former. The state of Rhode Island has an area of 1,250 square miles. If this state were wholly planted in grass and yielded as much hay per acre as the average meadow, enough food would be pro- duced in the course of a summer to sup- port a maximum of about 2,150 of these great whales for a year; the District of Columbia could sup- port less than 125.

Yet whales are abundant in certain regions. I have my- self seen on the Pa- cific more than a hundred atone time, though these were of a kind much smaller than the Blue whale. At the height of the whale fishery at Spitzbergen the catch averaged slightly over a thou- sand whales a year, all large ones. The food of those that were killed, not considering those left alive, would represent the grass crop from an area eight times the size of the District of Figs. 415-419.
