PREPARATION FOR A COLLECTING TRIP. 



humanely as possible, and will not destroy more than 

 we need for our work. 



The objects of this lesson are two : first, the 

 suggesting of a proper spirit in which to take up 

 this work ; and, second, the getting ready for our first 

 field trip, so that when the time comes to start there 

 will be no delay. 



The most important thing to carry with you into 

 the field is a good pair of eyes. Without these but 

 little will be accomplished. 



Of the various kinds of collecting apparatus the 

 most important is a cyanide bottle. Each pupil, if 

 possible, should have one of these. On page 286 will 

 be found directions for making them. 



In addition to a cyanide bottle it will be well if 

 each one has an insect net, although much can be 

 done without a net. See page 285 for a description 

 of an insect net. 



No other apparatus is needed for the first field 

 trip, but it will be well if some provision be made at 

 once for preserving the insects that you are going to 

 collect. The following are the more important 

 things needed for this : 



1. An insect case or empty cigar-boxes. Read 

 what is said on pages 306 to 310 regarding these, and 

 note especially what is said on page 310 regarding 

 the use of corn pith for lining cigar-boxes. 



2. A supply of insect pins or, if these can not be 

 obtained, a paper of ordinary pins. Read what is 

 said on this subject on pages 295 to 299.
