it has a remarkably high percentage of chlorine, leading one to sus- 

 pect the presence of scapolite, as was suggested by Dr Hillebrand. 

 A trace of carbon was found in this sample recalling the results 

 just stated under the Lincoln Pond pit. 



The Oak Hill pit is a small one, in gabbro like the others.

In the quantitative system this ore has the same series of names 

 as the one last mentioned from Lincoln pond. 



Titaniferous ores in Moriah. The presence of a titaniferous 

 body near Cook shaft, north of Mineville, but actually in Elizabeth- 

 town has been earlier remarked. The possibility of the presence 

 of titanium in the Craig harbor bed has also been suggested. Be- 

 sides these, however, several occurrences have been mentioned to 

 the writer by Mr S. Lefevre, chief engineer of Witherbee, Sher- 

 man & Co. Specimens have been brought in from time to time to 

 Witherbee, Sherman & Co., for analysis, but the writer has not 

 seen the occurrences in the field. Little if any work had been 

 done upon them, so far as known, and while in the field, they were 

 not noted. The bodies are liable to appear in any of the gabbro 

 areas. 



West of Mineville is Mt Tom on whose western side is a high- 

 way which is prolonged in a trail to Newport pond. An occurrence 

 is reported somewhere near this trail. 



Another occurrence has been reported about a half mile due north 

 of Feeder pond, in the southwestern shoulder of the hill reaching 

 ]640 feet. 



About 2^ miles west of Moriah Corners (or Moriah on the 

 map), a highway turns due south, and at ^ of a mile bends sharply
