From the fourteenth level, 100 feet in the south drift: 



(1) Trap. (54267.) 



(2) Barren aniyjrflaloid. (.')4an:l.) 



From the first level, 50 feet south of No. 3 shaft: 



(1) Trap rock, showing sheet copper at the contact between the two beds. 

 (54308.) 



(2) Foot wall, containing many small amygdnles, .some of them filled with reddish 

 laumontite. (54298.) 



From the eleventh level south of the shaft a specimen is shown which 

 is apparently a conglomerate of amygdaloid rock. (54209.) 



From the twelfth level, 400 feet north of the shaft, in a stope 30 feet 

 high, where the vein is 8 feet wide : 



(1) Trap, adjoining the hanging wall. (54254.) 



(2) Barren vein rock, showing small amygdules of calcite, (54255.) 



From the twelfth level, north of the shaft, three samples of crystal- 

 lized copper are shown. (54289.) 



From the thirteenth level, at the north end of the drift, where the 

 vein is 8 feet wide, and where there is a chute 15 feet broad : 



(1) Richepidote rock, containing ninch free copper. (54256.) 



(2) Barren vein rock, 7 feet from hanging wall. (542.57.) 



From the bottom of the shaft at the fourteenth level, directly on the 

 contact : 



(1) Trap rock. (54258.) 



(2) Ore, amygdaloid containing much free copper. (54307.) 



From the fourth shaft, second level, 100 feet south of shaft: 



(1) Trap, slightly amygdaloidal, from hanging wall. (54320.) 



(2) Ore, amygdaloid with free copper. (54302.) 



From the fifth level south stope : 



(1) Free copper, iu sheets, taken from the contact between the bed and hanging 

 wall. (.5429L) 



(2) Ore, amygdaloid, with free copper in small amygdnles, and also in sheets ; sam- 

 ple taken next to the hanging wall. (54282.) 



(3) Ore, amygdaloid with free copper; characteristic sample. (54249.) 



(4) Barren vein rock, trap with small amygdnles. (.54272.) 



From the seventh level at the end of the drift, G50 feet south from 

 the shaft : 



(1) Trap rock. (54250.) 



(2) Barren vein rock, amygdaloid with amygdnles filled with calcite and reddish 

 laumontite. (54277. ) 



From the ninth level, 50 feet south of shaft : 



(1) Trap rock. (54251.) 



(2) Parting from contact. (54294.) 



(3) Ore, epidote rock with much free copper, 5 feet from hanging wall. (54314.) 



From the tenth level, 300 feet from the shaft : 



(1) Barren vein rock, amygdaloid with small-sized amygdules filled with calcite. 

 Characteristic sample of a 250-foot streak of hard ground without copper, taken 2 

 feet from hanging wall. (.54253.)
