The coal enveloping these fragments must have been softened sufficiently to allow them to penetrate it, but it has more numerous and less regular divisional planes than in the central parts of the mass, and has probably been shifted or crushed somewhat, either when it re- ceived the included fragments or subsequently. Both at the roof and floor, the coal shows distinct evidence of a former pasty or fluid condition, in having injected a pure coaly substance into the most minute fissures of the containing rocks. On both roof and floor also, but espe- cially the latter, there are ubumhuit evidences of shifting and disturbances in the slickenside surfaces with which they abound. All these appearances I have endcavotnxd to represent in Fig. Gf), which agrees in the essential points with a similar figure given by Professor Taylor, who does not, however, repre- .sent the contorted state of the beds and the crushing of the lower side of the coal. " The levels of the mine extend on both sides of the shaft along the course of the coal. On the south-west they extend about 170 feet, when the coal narrows to a thickness of one foot. In this direction, however, I had not time to examine them. In proceeding to tlic , the coal has a general course of N. 50° E., bending gradually to N. fi5° E., and everywhere presenting the appearances already noticed, though attain
