24 Mr. William Phillips's description 



the south of the west, at a certain point, whence they run together 

 for about fifty fathoms. The united lode is about twelve feet wide, 

 and takes a direction nearly east. The underlay* of these lodes is 

 north ; the Great Gossan Lode about two feet, the Muttrell Lode 

 one foot ten inches, and the united lode one foot nine inches, in the 

 fathom. The two lodes are about thirty-seven fathoms apart at fifty 

 fathoms west of the point where they meet ; from which place they 

 have been worked, respectively, the Great Gossan Lode about two 

 hundred and thirty fathoms, and the Muttrell Lode seventy fathoms, 

 at the adit level. f They afterwards run on together about forty 

 fathoms in Huel Gorland mine, and further east form a valuable part 

 of the rich and extensive mine called Huel Unity. Huel Gorland is 

 in granite. 



In that part of the mine where the two lodes are separate, the adit 

 is fifty fathoms from the surface, but after they have run together 

 some distance, it is only forty fathoms, the descent of the hill being 

 towards the east. The adit being nearer on a level than the surface 

 of the country, it is, therefore, in noticing the depths of different 

 parts of a mine, most correct to date from the adit level, as is the 

 practice of miners. The depths hereafter given are so dated. 



In the two lodes, the red oxyd of copper was found under very 

 different circumstances. In the Great Gossan Lode it occurred 



* The generality of the lodes in Cornwall run nearly east and west; their downward 

 direction is not quite perpendicular, but generally more or less inclining to the north or 

 south. This inclination is called the underlay of the lode. 



+ It is the first object of a miner, in the working of a mine, to drive a passage or adit 

 from the nearest low ground or valley to meet the shaft, for the purpose of conveying oflf 

 the water, which is raised to the adit level by the means of the steam engine. It will 

 therefore be obvious that the depth of the adit from the surface of the mine, must depend 

 on the height of the ground iu which the mine is, and the depth of the neighbouring 

 Tallcy.
