Premise: If you do n't believe me , just look in it , '' retorted Blacky .<br>At once they all began to fly over the top of the tree where they could look down into the nest and there , sure enough , was Mrs. Hooty , her great , round , yellow eyes glaring up at them angrily .<br>Such a racket !<br>Right away Hooty was forgotten , and the whole crowd at once began to torment Mrs. Hooty .<br>Only Blacky sat watchful and silent , waiting for Mrs. Hooty to lose her temper and try to catch one of her tormentors .<br>He had hope , a great hope , that he would get one of those eggs .
Hypothesis: Mrs. Hooty's nest was not visible by flying over the tree.
