4 CATERPILLARS AND THEIR MOTHS 



the birth of many a rare caterpillar and its career to 

 the "perfect insect" or to an untimely and much-la- 

 mented death. It has witnessed our struggles, in the 

 beginning of our work, for a knowledge which no book 

 gave us, our experiments in ways of caring for our 

 crawlers, our discoveries with regard to their structure 

 and habits, our successes and our failures. It has 

 heard — if "walls have ears" — our desperate declara- 

 tions that when we wrote a book about moths and 

 caterpillars it should contain every detail of which we 

 had felt the need and which we had had to learn by 

 years of observation, experiment, study, and repeated 

 failure. 



The Crawlery is a most convenient and pleasant room, 

 with a north window for our microscope and a west 

 window in front of which is a wide shelf, used as a 

 table when we work over our caterpillars and holding 

 our scissors, forceps, magnifiers, and cleaning-brushes, 

 with an empty tin or two. 



Opposite are our book-shelves, which hold our work-
