Mr, S. Van Pelt presided over this last meeting, which prac- 

 tically ended the Symposium. 



Some of the members had left already and others intended to 

 leave on the following day. Several stayed over until Monday 

 and a few stayed several days longer. Those who remained ex- 

 plored the region about Newton more fully. Among the inter- 

 esting finds not previously noted are these : Androvieda Polifolia 

 L. and Carex liniosa L. found by Mr. Van Pelt, Rhaviniis alni- 

 folia L'Her. by Mr. Long, Triglochin maritivia L. by Dr. Elsie 

 Kupfer, Trollins laxiis Salisb. by Prof C. S. Williamson, Dryop- 

 tcris Boottii (Tuckerm.) Underw., D. cristaia x viargiitalis Dav. , 

 and Filix Indbifera (L.) Underw. by the writer. 



A great many interesting finds are yet in store for the botanist 

 who has the opportunity of spending more time about Newton, 

 where nature is still quite undisturbed in many places. This 

 applies perhaps as well in the case of the zoologist, as the many 

 fearless chipmunks and numerous birds and other wild animals 

 testify. Most of us were too much intent upon noting the plants 

 to make records of the wild animals seen, except in the case of 

 the birds. These were noted by Mrs. H. A. DeCoster, who 

 made a list of them. 



It is expected that the next Symposium will be held at Town- 

 send, Delaware, or somewhere on the Delaware peninsula.
