74 THE PLANT WORLD. 



wealth of spring and summer lead up to the Composltm and the 

 autumn abundance. The UnibeJUfeixe, the LaljiatcB are here repre- 

 sented, and many other families; in a word, it is a treasure spot to the 

 botanist. 



Doubtless each locality has had such a spot until eradicated by en- 

 croaching civilization. 



But already the work of destruction goes on. There was a time 

 when the ginseng, cimcif uga, spikenard, &c. , flourished, but these have 

 been appropriated by the "herb doctor." ' 



Do we not owe a duty to posterity in making an attempt to save 

 a tract like this intact for future students in the neighborhood of each 

 city, town or college? If the government purchases and preserves the 

 birth place of a great man, the field of a celebrated battle, why not a 

 strip of mother earth, rich with indigenous vegetation? 



A little Nature Park, hedged in from the thoughtless maraerdu, 

 but open to the student and lover of nature. Can anj^ acquisition 

 be worth more to a Natural History Club or Scientific association? 



Ladies' clubs might well consider this in connection with their 

 interest in ornithology. In a Nature Park the birds flourished undis- 

 turbed; left to the precarious shelter of cultivated grounds, only the 

 tamer species will be likely to remain.
