 cleared the way for others to follow, in a field where the difficulties are 

 undeniably great, but where the rewards to an earnest seeker 

 Tlie after Nature's secret ways are abundant. They are had not only

 ness of having added to human knowledge and enjoyment, but 

 in the higher satisfaction of having contributed somewhat to man's knowl- 

 edge of the works of his Creator. 



The author would count himself faithless to truth as well as to duty 



were he not to add that the last named consideration has been to him a 



continuous stimulus and support. He believes thoroughly in 



Author's j.} mt v i ew O f Divine Providence taught him by beloved parents 



M ^ in his childhood which makes it to be God's " most wise and 



powerful preserving and governing all His creatures and all 



their actions." The smallest creatures and the lowliest adventures of their 



humble lives are within the care of the Good Father of all, the Lord of 



spiders as well as the God of men. To bring all knowledge uncovered 



from the secret places of the natural world, and lay it devoutly before the 



world's Creator as a tribute of worship and a token of spiritual fellowship, 



has been the chief motive which has urged the author to, has guided him 



1 through, and sustained him in, this work of twenty years, now happily 



ended.
