GEOLOGY OF MOOSE RIVER GOLD DISTRICT WOODMAN. 79 



for crusbinor. There are said to be tbree leads between the 

 Copper and No. 7 ; but I have never seen them, as they were 

 met only in an old cross-cut, long since abandoned. Somewhat 

 more slate is found in the country rock to the Little North. 

 This again is really a belt of two leads, with two feet between 

 them, in which some whin occurs with the slate. Altogether 

 there are about four inches of quartz, rolling west at a very 

 low dip. Some little whin is to be found between the Little 

 North and Big North ; but the rock is chiefly slate, with many 

 veinlets of quartz interstratihed. The Big North (pi. 14) is in 

 a belt, with a whin hanging wall. The main lead lies on this 

 wall, and averages four inches thick ; is very curly, and has 

 west-dipping rolls. The Serpent is perhaps the most irregular 

 lead in the district, in places as low as two inches or somewhat 

 less, in others as high as eighteen. It is extremely well corru- 

 gated, but unevenly, the thickest parts giving the largest and 

 roundest curves (pis. 15, 16). It is remarkable for the clearness 

 with which the relation between the crenulation, cleavage and 

 jointing are shown in the sediments. This lead, better than any 

 other, brings out the manner of breaking of the vein parallel 

 with the laminae of the slate. 



Division ii : coinparison with " West Mine." — It may be 

 well to turn aside here, although not in the geographical order 

 o£ treatment,- to describe the leads at West Mine ; for they 

 are stated by their prospectors to be equivalent, in part at least 

 to leads just described in the main settlement. At the head of 

 the north trench (pi. 1, tig. b) is a four-inch lead. In the four- 

 teen-foot belt a few feet south of it is a ten-inch vein on the 

 foot-wall, and many stringers north of ii through the slate to 

 the limit of the belt. This is tiiought to be No. 7. The lead 

 in the east-west trench, with a steep rolling north dip, is 

 regarded as the Copper. The shaft south of this cut is over 

 the Little North belt, eight feet wide with three leads — one on 

 each wall and one in the belt. Southeast of this shaft is the vein 

 thought to be the Bis: North. Here is a six-foot belt with a
