The lode a is thrown upwards 25 fathoms ; but between b' and 

 b" the slide is divided, and between its branches a' was found, 

 so nearly resembling the lode in composition that it is con- 

 sidered as a portion of the same." 



" A very complicated example of throws^ occurring in Huel 

 Peever mine, has been recorded by Mr. John Williams *, in 

 which one lode throws another, and are both in turn thrown 

 by a slide. The tin lode aaa a, and John's gossan-lode b b, 

 bear about 10 S. of W. ; the dip of the former is about 

 70 S., and of the latter about 55 N. : the slides c c and dd 

 run nearly parallel with the lodes ; they are composed prin- 

 cipally of clay, with a little friable quartz. The mine was 

 worked in slate, near Redruth.
