BEAVER CREEK. 



West Kootenai district, British Columbia. 



Latitude, 51 10" N.; longitude, 117 30 7 W. 



Stone. Crystalline spherical chondrite (Cck) of Brezina; Sigenite (type 35) of Meunier. 



Fell between 3 and 4 p. m., May 26, 1893; described 1893. 



Weight, 14 kgs. (31 Ibs.) 



A detailed description of this meteorite was given by Howell,* Hillebrand, 4 and Merrill s 

 as follows: 



In the number of "Science " dated July 21, 1893, I (Howell)gave a brief history of this meteorite as then known, 

 and proposed the above name from the stream near which it fell. 



The accompanying cut gives a fair idea of the stone as first seen by me. It measured 6 by 7 by 9.5 inches and 

 weighed 22.5 pounds. About 3 or 4 pounds had been broken from the bottom as shown in the cut. The original weight 

 must have been approximately 26 pounds and the length 12 inches. 



After repeated efforts and much correspondence I have been unable to secure any more of the fall. The reports 

 at first stated that two smaller pieces of a few pounds each were seen to fall. This, however, seems to have been a 

 mistake, as only one other piece of 4 or 5 pounds, so far as I can learn, was seen. A portion at least of this smaller 

 piece was broken into fragments and distributed the same as the most of that which was broken from the larger mass 

 before it came into my possession, July 6, 1893, by purchase from Mr. James Hislop, a civil engineer, who found and 

 dug it up the morning after it fell and brought it to Washington. It buried itself in the earth about 3 feet 2 feet in 

 soil and 1 foot in hardpan. 



The direction of the hole was south 60 east, true meridian, and at an angle of 58 with the horizon. Fresh earth 

 was scattered about the hole in all directions, but farthest (10 feet) in the direction from which the stone came. 



It fell between the hours of 3 and 4 p. m. May 26, 1893, near Beaver Creek, West Kootenai district, British 

 Columbia, a few miles north of the United States boundary and about 10 miles above where the creek joins the. Columbia 

 River. 



The report was heard by persons within a radius of nearly 25 miles, and it was believed by many who heard it 

 that larger pieces must have fallen than those secured. The stone is a typical aerolite of very pronounced chondritic 

 structure, has the usual fused black crust, but has one feature unlike any other meteorite with which I am familiar. 

 Beneath the crust there is a slight oxidation for a distance of from one-half to three-quarters of an inch which seemingly 

 must have occurred before it struck the earth, and for which thus far no satisfactory explanation is suggested. 



There is no occasion to further describe the character of this stone as that part will be found fully discussed in the 

 accompanying paper by Doctors Hillebrand, of the U. S. Geological Survey, and Merrill, of the U. S. National 



Museum. 



CHEMICAL DISCUSSION BY DR. W. F. HILLEBKAXD. 



The material received for chemical examination was in a crushed state, much of it in fine powder, being the waste 

 resulting from cutting the rocky mass. There was scattered throughout it some organic matter derived from a burnish- 

 ing brush, which, though insignificant as regards weight, rendered useless any attempt to look for organic matter proper 

 to the meteorite itself. 



Of this mass, 26.1892 grams, after repeated separation under alcohol by an electro-magnet, yielded 5.0710 grams of 

 magnetic material which still contained over 10 per cent of unmagnetic substance, as shown by the following analysis:
