Minerals Occurring in the Neighbor-

During the past summer and autumn 

 Mr. G. F. R. Tackson and I took a 



LLMONITE AFTER PYRITE ALBEMARLE 

 COUNTY, VIRGINIA 



good many tramps in Albemarle Co., 

 Ya., with the three-fold object of en- 

 joying the fresh air and exercise, ob- 

 serving and discussing the rather com- 



plex ( ieology of the region, and collect- 

 ing all the different species of minerals 

 and rocks that could be brought to 

 light. When the desire to make a 

 mineral collection first took hold of 

 me, I naturally asked the question; 

 What minerals (in a state approach- 

 ing purity) could be found in and 

 around my home. The answer as it 

 came from others was not encouraging, 

 and indeed my first searches were al- 

 most fruitless. Air. Jackson and I, how- 

 ever, determined to investigate 

 thoroughly, and were rather agreeably 

 surprised to find about a dozen speci- 

 mens, which I consider not contempt- 

 ible illustrations of the varieties they 

 represent. The purposes of this little 

 article are two: viz., to encourage the 

 study of Mineralogy, especially by the 

 method of seeking the earth's constit- 

 uents where they have been differ- 

 entiated and lie hid in their rocky or 

 earthy homes, and to give to those 

 locally interested and to those inter- 

 ested in the geographical occurrence of 

 minerals generally some little account 

 of what is available. A brief des- 

 cription of each specimen and its mode 

 of occurrence follows.
