one t)f the northern tier counties of I'ennsylvania. 'l"he entrance 

 to the park is ahout ten miles from the town of Wellshorcj. Most 

 of the i)arty arrived hri(la\- evening. Some stayed at a cahin camp 

 near the park and others in Wellshoro. 



The so-called canyon has been formed by Pine Creek. For 

 miles it has cut through the mountains. It is about 1,000 feet from 

 the rim to the level of the stream. After the group assembled for 

 the morning trip a little time was provided to take in the extensive 

 view of the canyon country from the park look-outs and to listen 

 to brief explanations of the geological and floral features. 



The Saturday morning route circled over the wooded hillsides 

 at the higher altitudes and included one minor ravine. Species 

 which attracted most attention were Pinus rcsinosa, Dirca paliistris, 

 and Rubus triflorns. Dirca is not a common plant of the region. 

 It was possible to locate other plants easily after the first one was 

 found as practically every leaf had one or more yellow spots 

 caused by Accidium hydnoidciim. This was the first collection of 

 the rust in Pennsylvania. The alternate stage which is on Carex 

 pcniisylvanica was not found. Other interesting species noted were 

 Conuis circinata. Solidago squarrosa, Louiccra canadensis. Micro- 

 sfylis unifolia, and Bctida alba. There was some discussion as to 

 identity of the varieties of the northern white birch. The white 

 pine blister rust, Cronartiuui ribicola. was found in the form 

 of old cankers on Pinus Strobus and in uredinial stage on Ribes 

 cynosbati. 



In the afternoon the trail to the canyon was followed. It is a 

 steep descent into the narrow valley of the creek — so steep in 

 places that steps were provided. Dry w^eather for several pre- 

 vious weeks had reduced the water-falls in this tributary gorge so 

 as to rob it of much of its usual charm. On an island in the valley 

 was an unusually fine stand of Onoclea Strnthioptcris. Here also 

 were found Botrychium virginiannm, B. mafricariacfoliuni, and 

 B. lanceolafuin var. angustiscguicntiini in surprising abundance. 

 The red-berried elder. Sambuciis racemosa. attracted some atten- 

 tion. 



A trip to a sphagnum bog on Armenia Mountain near Sylvania 

 was planned for Sunday morning. This meant going by automobiles 

 along U. S. Route 6 to a point about thirty miles east of Wells- 

 boro and then following a dirt road for several miles southward.
