crinites, &c. Concluding that they must have come from a source 

 higher up the stream, I retraced my steps a few rods, where I ob- 

 served a ravine in which ran a small stream of water, over the rocks 

 which appear to constitute the ridge of hills upon the eastern side of 

 the valley. I had walked but a short distance up this ravine or run 

 of water, before I discovered, in place, the specimens which I send 

 you marked E. From these indications, and from information sub- 

 sequently obtained, there is reason to believe that at the base of this 

 ridge, and on or near the margin of the rivulet in its course to the 

 Potomac river, there are strata or deposits of organic remains ; as I 

 was informed that at the foot of a mill dam situated lower down 

 upon the same rivulet and nearer the Potomac, a variety of speci- 

 mens of organic remains are to be found. I have also received in- 

 formation, from a source that I believe may be relied on, that the Tri- 

 lobites, in fine preservation, have been and are still to be found higher 

 up the rivulet or south of the springs, and which, probably, have been 

 washed out of the same ridge j of this part, however, I was not 

 aware when at the springs. 



I have been thus, perhaps unnecessarily, particular that those who 

 may hereafter visit this district, and who feel a pleasure in investiga- 

 ting subjects of a nature and character so interesting, may be led to 

 the respective localities with the least trouble or fatigue. 



Remark by the Editor. 



The organic remains mentioned by Dr. Hayden, are such as be- 

 long to the ancient secondary or transition. The specimens having 

 been accidentally misplaced, I am not able to describe them more 

 particularly, as requested by Dr. Hayden : I recollect, however, that 

 several of them belonged to the ancient coralline and encrinital 



families ; the petrified butterflies of the common people, it is well 

 known, are trilohitRs. a« Dr tt<^,A nn u nr , :„„*l. :„j: .~j
