These numbers correspond with those in Kirkman's British Birds (Jack), the 

 most excellent pocket-book on the subject published. The intention is that the 

 young reader should carry one of these about with him on his rambles. Indeed, 

 I most strongly advise him to get a copy, and interleave it with blank pages on 

 which he can make notes. I can scarcely over-emphasize the value of the 

 pocket-book thus made, if the young student will add his own original notes 

 to the admirable descriptions given by the author. It is the sort of book which 

 should accompany him on every bird-observing expedition. Another most 

 valuable exercise is to colour the plates of birds from direct observation.
