186 TRAP-BOOR SPIDERS. 



and what do they fear ? we should have advanced a 

 long way towards resolving the larger problem as to 

 the causes which limit particular species to certain 

 districts. 



I greatly envy those who are able to travel, and 

 who have it in their power to investigate the habits 

 of these creatures at several widely sej)arated points ; 

 for there seems every probability that other new types 

 of nest remain to be detected in warm climates, some 

 of which may perhaps exceed those we have been 

 here studying in beauty of workmanship and adapta- 

 tion ; it is at least certain that an abundant harvest of 

 interesting facts in the life history of trap-door spiders 

 remains yet to be gathered in. 



Indeed it appears to me that we are only on the 

 threshold of discoveries of this kind, and that the 

 materials brought together in tlie preceding pages 

 may be considered as but a small sample of what may 

 be collected on the outermost edge of this great 

 domain. 



I shall be satisfied if I have been able in the present 

 little work, to hold the door sufficiently ajar to permit 

 those who love nature and her ways to catch a glimpse 

 of the wonders and beauties of the untrodden land 

 that lies beyond.
