WEYER’S CAYE. 
As stated by Mr. Hovey, the caves of the Shenandoah Valley are smaller than those of Ken¬ 
tucky and Indiana, owing to the fact thatthe 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 u the eastern side of a ridge running parallel to the Blue Ridge, 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 MARKET 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 6 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.
