" the crane so addressed was of extraordinary size , and had arrived at a great old age , and , as might be expected , he sat , when first descried by the two sons , in a state of profound thought , revolving his long experience of life there in the midst of the most violent eddies . when he heard himself appealed to , the crane stretched forth his neck with great deliberation , and lifting himself slowly by his wings , he flew across to their assistance .

"
