462 THE ANIMALS AND MAN 



Each pupil should keep a field note-book, recording 

 from day to day, under exact date, any observations he may 

 make. Let the most trivial things be noted; when referred 

 to later in connection with other notes they may not seem 

 so trivial. The field note-book should be smaller than the 

 laboratory note- and drawing-book, small enough to be 

 carried in the pocket. Notes should be made on the spot 

 of observation; do not wait to get home. Sketches, even 

 rough ones, may be advantageously put into the book. 

 Students with photographic cameras can do some very 

 interesting and valuable field-work in making photographs 

 of animals, their nests and favorite haunts. Such photo- 

 graphic work is very effectively used now in the illustration 

 of books about animals and plants (see the reproductions 

 of photographs in this book). If the class is making a 

 collection the collecting notes or data made in the field- 

 books of the different pupil collectors should all be trans- 

 ferred to a common "Notes on Collections" book kept by 

 the whole class. 



Equipment of schoolroom.- -The equipment of the 

 classroom or laboratory will, of necessity, depend upon the 

 opportunities afforded the teacher by the school officers to 

 provide such facilities as instruments, books, and charts. 

 If dissections are to be seriously and properly made, how- 

 ever, some equipment is indispensable. Flat-topped tables, 

 not over 30 inches high, a few compound microscopes (one 

 is much better than none), as many simple lenses, or, far 

 better, simple dissecting-microscopes, as there are students, 

 dissecting-dishes, a pair of bone-clippers, one injecting- 

 syringe, a bunch of bristles, water, a few simple reagents 

 and some inexpensive glassware, as slides, cover-glasses, 

 watch-crystals, and fruit- or battery- jars for live cages and 

 aquaria, make up a sufficient equipment for good work. 

 Much can be done with less, and perhaps a little more with 

 some additional facilities. 



The dissecting-pans should be of galvanized iron or tin, 

 oblong, about 6x8 inches by 2 inches deep, with slightly 

 flaring sides. If an iron wire be run around the margin,
