what they love to call the " filices." The thirst for 

 knowledge, however, was on me, and when, a few 

 years later, on these Berkshire roadsides I found the 

 ferns more luxuriant than ever, and in larger variety, 

 the determination seized me to know something about 

 them, and, on the foundation laid for me by the wise

 of those who still stand outside this delightful cir-

 introduction, that I record this personal experience, 

 and some suggestions for the benefit of those who 

 love the ferns, but know them not. 



They are not hard to become acquainted with. If

 the common ferns. A good magnifying-glass is all 

 the equipment which is absolutely necessary ; and 

 Gray's Manual is a good enough guide to start

 mature into the true seeds of the plant ; and the ferns 

 are classified according to the shape of these " sori,"

 of the frond distinguish the varieties from one
