Trip of July 12 to Surebridge Swamp, Interstate Park 



Surebridge Swamp, a high, cold, forested swamp, at an alti- 

 tude of about 1,000 feet, in the western part of the Harriman 

 Section of the Palisades Interstate Park, was visited on July 12. 

 A new station was found in the depths of the swamp, unusually 

 penetrable owing to dry weather, for the Virginia Chain 

 fern, Woodwardia virginica. The red fruited sorediate lichen, 

 Chidonia incrassata, not common in the Hudson Highlands, was 

 rather extensive here about bases of red maple trees. On the 

 "Lichen Trail," climbing the ledges of Hogencamp Mountain, 

 the only really ample station in the Hudson Highlands, of the 

 Iceland Moss lichen, Cetraria islandica, was noted, other lichens 

 on the glaciated ledges and boulders lying on them were 

 Stereocaidon paschale, Rinodina oreina, and Lecanoras . Cladonia 

 rangijerina, the Reindeer Moss, C. sylvatica, C. chlorophaea, and 

 C. strepsilis occur along the edges of the open ledges. 



A sally off the trails into a gully leading off the west side 

 of Hogencamp Mountain, disclosed some very clear slicken- 

 sides, another evidence of the great over-thrusting which oc- 

 curred on the west side of the Highlands of the Hudson in the 

 Taconic Revolution. Swamps traversed on the way out to the 

 Crooked Road past Island Pond, disclosed many robust mosses, 

 especially large Mniums, and the hepatic, Bazzania trilohata, 

 was common.

Trip of August 9 to Gardiner's Island 



The train and boat trip to Gardiner's Island, at the east end 

 of Long Island, one of the most interesting events of the field 

 schedule, turned out this year to be a veritable armada, with 

 two boats required to carry the 48 members and guests from 

 other groups. The trip was made possible by the kindness of 

 Mr. Clarence H. MacKay, lessee of the island. 



When the boats landed, after the eight mile sail across 

 Gardiner's Bay, the party broke up into groups interested in 

 plants, birds, or geology. All saw the old Gardiner burying 

 ground, with stones dating from the middle of the seventeenth 

 century, all but the very newest decorated with young to very 

 ancient colonies of the lichen, Rinodina oreina, derived, evi- 

 dently, from a red granite boulder transported from somewhere
