oven. Herbarium specimens were thus obtained which have 
not since lost their leaves. 
The banks of the Hawksbill were blue with Lupatorium 
celestinum, L.. Among introduced plants along the roadsides 
grew Xanthium spinosum, L., and Filago Germanica, L.; and 
everywhere growing as weeds, were seen Solanum Carolinense, 
L., with white and blue flowers, and Szda spinosa, L. The most 
abundant Conifer was Pzuus mitis, Michx., on whose leaves the 
stomata were conspicuous with a pocket lens, arranged in longi- 
tudinal rows on both sides. Pinus inops, Aiton, is very abun- 
dant elsewhere in the valley, but was not noted at Luray. The 
only form of vegetation seen in the famous caverns was the 
mycelium of a fungus growing on wet planks. 
The list of plants noted at the Natural Bridge of Virginia is 
much too long for insertion here, but the following warrant men-

the Bridge, grew Heuchera villosa, Michx.; Draba ramosissima, 
Desv.; Samolus Valerandi, L.,; var. Americanus, Gray; Sedum 
ternatum, Michx.; Rhus aromatica, Ait.; Feffersonia diphylla, 
Pers.; Hydrophyllum Canadense, L., and H. Virginicum, L.;

Willd.; Astmina triloba, Dunal; Pellea atropurpurea, Link; 
Asplenium Ruta-muraria, L.; Cystopteris bulbifera, Bern.; and

Hloustonia purpurea, 1., var. longifolia, Gray; Calamintha 
Wepeta, Link; Asclepias verticillata, L.; Polygala ambigua, 
Nutt. ; Linum sulcatum, Riddell, with showy yellow flowers— 
which dropped off when touched—and Salvia lyrata, L. The 
large trees of Arbor Vitae along the walk leading under the 
Bridge were remarkably fine; one of them measured fourteen 
and one-half feet in cies: 
At Balcony Falls, where the James river cuts through the 
Blue Ridge, we collected Campanula divaricata, Michx. ; Dicen- 
tra eximia, DC., in full bloom on September 5. Coreopsis sent- 
Jolia, Michx., andC. verticillata, L., were showy along the railroad — 2 
track. Paronychia argyrocoma, Nutt.,and Hypericum prolificum, L.,
