Look at that mallard as he floats on the lake; see his elevated head glittering with emerald green, his amber eyes glancing in the light! Even at this distance, he has marked you, and suspects that you bear no goodwill towards him, for he sees that you have a gun, and he has many a time been frightened by its report, or that of some other. The wary bird draws his feet under his body, springs upon then, opens his wings, and with loud quacks bids you farewell.
