New York City. There is no record concerning the collestor or 

 the date when collected. 



The meteorite is about 10 inches by 12 inches by 24 inches and is 

 composed chiefly of iron. The constituents are given as foUowes : 

 Iron 89.17 percentt, Nickel 9.72 percent, Cobalt 0.67. The weight 

 is 355 pounds. 



On freshly cut faces which have been etched particularly good 

 widmannsttatian figures. There have been several reported occur- 

 rences of meteorites in Oklahoma. Some material recently exainin- 

 ed from northern McCurtain County indicate that the material is a 

 part of a meteorite. 



The toughness of the iron meteorites is dv:e to the presence of 

 nickel and the fact that they were so difficult to cut is said to 

 have led to the adoption of an alloy of nickel and iron in making- 

 armor plate for battleships. 



It should be a matter of interest to be on the lookout for 

 meteorites over the State as well as to observe the "shooting stars" 

 in the sky. 



PRESENT STATUS OF COPPER MINING IN 

 GARFIELD COUNTY 



A. F. Reiter, 1920. 



At this time three shafts are being sunk for copper. One, a 

 mile and a half east of Hillsdale on the Taylor farm, is at this 

 time 20 feet deep with only slight indications of copper. The sec- 

 ond, a half mile west of Hillsdale, has reached a depth of 62 feet 

 with a slight trace of copper. This shaft is on the Laming farm. 

 The third is a mile and a half southwest of Hillsdale on the Barnes 

 farm and has reached a depth of 72 feet. Operations here have 

 been interrupted by water which now stands 40 feet deep in the 

 shaft. Agood vein of copper was found in his shaft at a depth of 

 32 feett and a second one at 70 feet. Copper occrfrs here in the 

 free form principally interspersed between layers of crystalline 

 gypsum or between layers of gypsum and red sandstone. There is 

 considerable copper in soil also not in the free form. 



Selected samples from this mine gave a milling test of 40 per 

 cent copper. The shaft run would probably not be over 5 per cent 

 for depths of about 5 feet in each copper bearing stratum.
