Professor Richardson, in his Elements of Geology, supposes acase, vrhere aland owner, aware that coal exists on an adjacent estate, isdesirous of ascertaining whether it may also be found on his own, andwhether an attempt to discover it might be instituted with probabilities ofsuccess. In this case the dip is almost the sole reliance. If the dip of thestrata in the vicinity be towards the land where the trial is to be made, itis highly probable that the coal may be found under it at a certain depth,which can be readily calculated ; but if it is in a contrary direction, thesearch ought not to be undertaken, (unless, on examination, the veinsshould prove to be broken and have a backward pitch, which sometimes happens.)
