tana and others species characteristic of the Adirondack region. 

 With a steep descent into the valley of the Little Hoosick River 

 we turned northward to Petersburg and then up the long wind- 

 ing "Mohawk trail" to the Petersburg Pass summit on the 

 Massachusetts line. The elevation here is about 2000 feet. Tliere 

 is a good lunch room here and an observation tower and park- 

 ing place for many cars. Our route took us northward along the 

 ridge trail through dense growths of low blueberries, Potenlilla 

 tridentata, Rhinanthus crista-galli, and many species of grasses 

 and sedges. 



In some places plants of Microstylis ophioglossoides were 

 observed along the trail, and near the end of this walk about a 

 mile north of the pass Dr. House pointed out two interesting 

 ferns, Botrychium obliquum (and its variety dissectiim), and B. 

 multifidum, closely resembling each other but different in tex- 

 ture, the latter having fleshy, evergreen fronds and the other of 

 much thinner texture as well as having longer and more pointed 

 segments than B. multifidum. There were fifteen members and 

 friends present on this week-end trip.

Trip of September 10 Along the Long Island 

 Terminal Moraine North of Hollis 



Twelve members and the leader took the walk Saturday, 

 September 10, along the Long Island terminal moraine, begin- 

 ning at 188th Street, Queens, just north of the Grand Central 

 Parkway. The walk led through what is now called Cunning- 

 ham Park, a wooded area showing on every hand a morainal 

 configuration — large and small kettle holes, irregular topog- 

 raphy, and boulders heterogeneous as to shape, size, and con- 

 stitution, hailing from somewhere to the northward. This long 

 ridge, extending through a large part of Long Island, is of ex- 

 treme interest, geologically, and it is indeed fortunate that at 

 least part of it has been preserved by the creation of Cunning- 

 ham Park. We hope that it will be allowed to remain in as 

 nearly its natural formation as possible. Botanically, the flora 

 of the kettle holes is of the greatest interest. In one, in which 

 water stands, evidently permanently, we found an almost 

 exclusive population of what appears to be Polygonum muhlen- 

 hergii (Meisn.) Wats, which agrees closely with P. emersum,
