1 1 . The Preliminary Survey a Practical Exercise. This 

 can be arranged to best advantage by dividing the class 

 into small groups of three or four students. These 

 groups should go out in different directions, the routes 

 being so arranged that all the most fruitful local regions 

 shall be visited by some of the parties. 



Every student should observe and make notes of all 

 the types of animal life that he finds, together with a 

 description of the natural conditions under which they 

 are found. 



Gardens,* orchards, and fields with growing crops should

 pests. 



The purpose of this exercise is to make the class appre-

 to take the best advantage of them. For this reason 

 the students should keep in mind the question as to 

 what implements and receptacles they will need when 

 they actually start out on their second and formal collect-

A comparison and full discussion of observations, 

 methods, and conclusions should be had in class. 



12. The Collecting Excursion a Practical Exercise. 

 Each student should select for careful study one or two of 

 of the localities found most fruitful and interesting in the 

 preliminary survey. Let it be understood that the purpose
