specimens in the State Ilerhariumj ; and Sc[jt. 24, 1913. I am 

 sure it appeared in 1914; but have no record. In 1915 fine (!) 

 specimens were developinj^; on this trunk: but the cattle in the 

 pasture somehow got to them and practically destroyed the lot. 

 This butternut trunk is yearly becoming more and more decayed. 



White Ash {Fraxinus americana L.). On a stump, in an open 

 grove, about one mile southeast of the butternut, July 6, 1907. 

 This was a poor deformed specimen, as I remember: and is 

 deposited in the State Herbarium. I have not found it since at 

 this station. 



Black Ash {Fraxinus nigra Marsh.). On a stump, lower falls 

 of North Beaver creek, Sept. 2, 191 2. On a log, some time 

 fallen but quite sound, July 24, 1915. During June, 1915, the 

 fine (!) specimens were discovered developing on this log: but 

 in spite of the fact the log lay under prickly ash bushes; the 

 herd of cattle pastured in the field, broke ofT most of the plants 

 and partly destroyed the punks, before the specimens were 

 collected. 



Black Willow (Salix nigra Marsh.). Ver}^ old weathered 

 plants were found on a much broken willow trunk, Nov. 12, 

 1 913, on the north bank of the Halfway brook, east of the 

 village of Tripoli. 



Glaucous Willow {Salix discolor Muhl.). A small specimen 

 found on a fallen trunk of this willow, Aug. 14, 1915, in Vaughns 

 schoolhouse woods. 



White Elm {Ulniiis americana L.). On the crossing log, over 

 Halfway brook, by the "electric power lines," east of Tripoli, 

 Oct. 4, 1914. Also found here on an elm log, July 25, 1915. 

 This station is about one mile north of the black ash station, 

 with several hills and valleys between. 



Sugar Maple {Acer Sacchariim Marsh.). On a stump in open 

 woods, several rods to the northeast of the butternut locality, 

 across an open pasture, Aug. 19, 191 5. A portion of the collec- 

 tions from black ash and sugar maple have been deposited in the 

 Herbarium of the New York Botanical Garden. 



Whether the plants at these different stations sprang originally 

 from one source is difificult to say. It is quite possible that the
