40 ANIMAL LIFE AND SOCIAL GROWTH 



location of these sample quadrats in a community 

 one knows as well as he does his own place of 

 business, the more I am impressed with the care 

 needed in the location of such areas for the study 

 of non-human animal life and for the use of data 

 so collected in making generalizations. Is a foot- 

 ball field characteristic? Certainly a survey 

 which omitted this locality would be incomplete 

 but its significance would be missed if the col- 

 lections failed to catch the crowds present for a 

 few hours on a few days in the autumn. Are 

 deans' offices typical, or students' lounging rooms, 

 or fraternity houses.'^ Shall a quadrat include the 

 university chapel or the cashier's office .^^ Which 

 laboratory shall we select, if any.^ Shall dormi- 

 tories, dining halls and libraries be represented.'^ 

 If so and if we find ourselves pressed for time in 

 making careful quadrat counts, which shall be 

 neglected or eliminated.^ By the location of a 

 sufficient number of quadrats and by the study 

 of the specimens to be found there during the 

 entire twenty-four hours of the day and for all 

 the seasons of the year, we can learn much of the 

 organization of a human community such as we 

 are considering. 



Having selected the quadrats with all the skill 

 and knowledge available, we must next decide 

 how we are going to study them. We may visit
