SCIENTIFIC SURVEY. 329 



ous belt in this vicinity. First, there is the great Oriskany sand- 

 stone belt, known to extend from Aroostook river to Parlin pond, 

 which is better developed at its most south-western limit known 

 to us than elsewhere in its course. This must extend further than 

 Parlin pond in this direction. Second, we find boulders of a pe- 

 culiar fossiliferous rock in Phillips, different from anything yet 

 seen by us in the State, which must have come from this vicinity, 

 or from the Kennebago region, judging from the common course of 

 the drift striae in the vicinity. These boulders were sent to us 

 by Seward Dill of Phillips. Third, a gentleman residing in New 

 Hampshire and employed in the topographical survey, informs us 

 of the discovery of fossils in situ near Umbagog lake. We give 

 here extracts from his letter : 



"I was at work with a party of our topographical engineers in 

 that region all last summer, from the Umbagog up the Megalloway 

 to its source, thence to the ' Crown monument,' and spent the 

 summer in that vicinity." " Since Dr. Jackson made his geologi- 

 cal survey of New Hampshire nothing has been done in that line, 

 and so while prosecuting the work on the topographical survey, I 

 have also given much time to the geology, and more particularly 

 to the mineralogy of our State." " While at work on the line of 

 Maine and New Hampshire, I have frequently made trips into 

 Maii'ie, until I feel very much interested in the geology and miner- 

 alogy of your State." " I am glad to know that you have discov- 

 ered a fossiliferous region in Maine. We put to rest forever, last 

 summer, the theory of many eminent savans that ' no fossil ever 

 existed in New Hampshire.' We have made important discoveries 

 in that direction, and have sent away many excellent fossils ob- 

 tained last summer, and got orders for more which we cannot 



fill," etc.

This is an important discovery, and we shall hope to hear further 

 from Mr. Mason on the subject. It will be remembered by scien- 

 tific men, that in Vol. I, (N. S.) of Silliman's Journal of Science, 

 Professors H. D. and W. B. Rogers gave some account of sup- 

 posed fossils discovered near the Notch, referring them to the 

 Clinton group of the Upper Silurian. Some of the supposed genera 

 were Agnostis, Cytherina, Atrypa and Lingula, besides fish scales.
