The .'ulvanta^es which Professor Herrick's method of bird study offers are obvious. It would have been ahnost impossible for a class of students to become as intimate with Cedarbirds as we became by any other method; every characteristic action, every posture, almost, is impressed on our minds. My experience with the Chebcc, however, forces me to the conviction that the method of controlling the nestinjj-site, of moving); it, in other words, for the purpose of study and of photography from the position which the bird has selected, is one which may, in careless hands, be productive of a great amount of injury. I believe that only a trained naturalist should use the method. Even he will probably have to buy a little costly experience, but if he is animated by genuine love for the indi- vidual bird, he will learn to guard against the dangers from heat, rain, and desertion. It is emphatically not a method to be recommended to the general public.
