the cave is a beautiful illustration of cave formation. When a freshet 

 or rain storm is in progress in the far-off mountains this stream is sure 

 to be affected. Residents say that the water comes out with such 

 force sometimes that one can hear it for miles. This then to me is 

 the secret of the whole thing. The mountain has been burst asunder 

 by the continued force of water. The Adianttun Capilhts-Veneris has 

 certainly an affinity for this geological formation. The carbonate of 

 lime and the water is its very life. There it grows, in its own selected 

 home, as it never grew before ; and it is to be hoped no hand of van- 

 dalism will ever destroy it. This scene is now a perfect gem of Na- 

 ture's handiwork, in every sense. 



I impressed Major Wallace, a gentleman who has some influence 

 in this quarter, with the importance of having this spot protected. 

 Next year there will be a great rush of visitors to this place, and, with- 

 out some restriction, they will soon uproot every frond. The fern is 

 found plentiful about two miles further up the river ; and those desiring 

 specimens can get them there. I may state I found this fern only 

 in places surrounded by such conditions as have already been men- 

 tioned.

73. Asplemum ebenoides, R. R. Scott, in New York State. — I 



send, herewith, a frond of Asplemum ebenoides^ R. R. Scott, which I 

 found yesterday (Aug. 6th), on limestone rocks about four miles S. 

 E. of Poughkeepsie. There were but three plants, and I secured but 

 three fronds. I will give the locality a more thorough looking over, 

 later on, and hope to find some more. Asple^iium ebejieimi, Ait., and 

 Camptosorus were, as usually the case, growing with it — all three 

 within a space of about a foot square. In these plants the veins anasto- 

 mose quite frequently — about 24 times in the frond that I have. Prof. 

 Eaton describes the venation in his specimens as everywhere free. 

 I have never seen this fern mentioned as having been found in New 

 York before; but, whether it has, or has not been, it certainly is very 

 scarce, and worthy of being recorded in the Bulletin.

74. Fendler's Trinidad Ferns.— The sets of the second, or sup- 

 plementary distribution, of this fine collection are now at Prof. Eaton's 

 Herbarium. Several sets (including the first distribution) are still 

 unsold. 



75. Dr. Garber's Porto Rico Plants are also for sale by Prof. 



Eaton. The sets run from 96 to 17 species, and are mostly interest- 

 ing plants. That most delicate of all itvn%,Truhoma?ies trichoideu??t, 

 is in all the sets. 



76. Notes from Syracuse.— P/^/?/,/^^^ /^/^^/t?, L., has been found 



in the streets. It resembles P. major.hwl has soft downy leaves and 

 sliorter petioles which^are not grooved; the spikes of flowers are 

 shorter, but the stamens are longer and brilliantly colored- Muhlen- 

 berg found it in Pennsylvania (Cat. 1813), but Dr. Gray says it is
