GEOLOGY OF MOOSE RIVER GOLD DISTRICT — WOODMAN. 47 



at the level of the fulcrum and near the axis, increasing 

 outward and above and below it. Such evidence as we have 

 indicates that the south dips of the north anticline were not 

 steepened appreciably in the change from 60° to 70° axial dip ; 

 hence if (1) is to be accepted, the direct sliding must have been 

 nearl}^ the distance of the offset of the north axis, or about ten 

 feet, the axis steepening 10° about a fulcrum placed close to the 

 present surface of the ground. Of the southern part of the sec- 

 tion, all that can be said is that in addition to the ten feet 

 absolute movement north, there was a farther one caused by- 

 compression, less northward and greater southward, amounting 

 at the southern axis to 37.5 feet at the most. This appears, of 

 the two, the more plausible explanation. In the course of 

 compression, the south anticlinal axis was decreased in dip 

 from 85° S. to 82° S. 



Middle fault : course and attitude. — The evidence as to the 

 functions of this fault are far clearer than of the one just 

 described. Its direction throughout its observed length is N. 

 19° E. At the north end it has been met in working the Cop- 

 per and Little North on the west, and these and the Little South 

 on the east. The last has not been opened west of the break 

 because, such is the lack of system in the development of these 

 districts, no cross-cut has ever been made for it. The workings 

 on these leads were abandoned in 1897 or 1898, and I have seen 

 the fault below ground but once. There it appeared as a zone 

 of fractured material, with a breadth not measurable at the time, 

 and dipping east at a very slight angle from the vertical. In- 

 deed, experience seems to show that most of the north-south 

 faults in this series, where their dip is measurable, incline east 



Middle fault : displacements. — If the Copper and Little North 

 had kept their strike eastward to this fault, their horizontal dis- 

 placement would be 95 feet. But instead, t\\&y turn strongly 

 northeast. In other parts of the district, some turn thus in the 

 direction of motion, and some do not. The former cases are 

 probably in the nature of a drag, except where the axis of the
