WEYEE'S CAVE. 



As stated by Mr. Hovey, the caves of the Shenandoah Valley are smaller tban those of Ken- 

 tucky and Indiana, owing to the fact that the Lower Silurian (probably Trenton) limestones out of 

 which they are excavated are much thinner than the subcarboniferous rocks westward. 



Weyer's Cave is situated in Augusta county, Virginia, 17 miles north of Staunton, and its 

 entrance is on "• the eastern side of a ridge running parallel to the Blue Eidge, from which it is 

 distant 4 miles." The cave is said to be 1,650 feet in length. It is a wet cave, the water 

 percolating from the red sandstone above, forming pools with muddy edges, but containing 

 no Crustacea or Planarians. According to Hovey the temperature is uniformly 54° Fahr. 

 (The temperature of the water and air taken by us were 55° and 56° Fahr.) An adjoining cave 

 situated farther on from the hotel is called by the proprietor " Cave of Fountains." This is 

 probably Madison's Cave, first described by President Jefferson, and we will consider the one we 

 entered as that. Within the entrance, near the steps, were detected two species of flies, and a few 

 Helices occurred, but no cave crickets or beetles.

THE NEW MAEKET CAVES. 



These caverns are situated about 6 miles southeast from the railroad station of New Market. 

 Zirkle's Cave is about a mile in extent. It contains a flowing stream G feet wide, besides pools and 

 miniature cataracts. We visited this cave in 1879 on our way to Luray Cave. The temperature 

 of the cave is said to be 56° Fahr.
